Details

Bugfix #1863: Report correct number of directories processed by backup

The directory statistics calculation was fixed to report the actual number of processed directories instead of always zero.

https://github.com/restic/restic/issues/1863
Bugfix #2254: Fix tar issues when dumping /

We've fixed an issue with dumping either / or files on the first sublevel e.g. /foo to tar. This also fixes tar dumping issues on Windows where this issue could also happen.

https://github.com/restic/restic/issues/2254 https://github.com/restic/restic/issues/2357 https://github.com/restic/restic/pull/2255
Bugfix #2281: Handle format verbs like '%' properly in find output

The JSON or "normal" output of the find command can now deal with file names that contain substrings which the Golang fmt package considers "format verbs" like %s.

https://github.com/restic/restic/issues/2281
Bugfix #2298: Do not hang when run as a background job

Restic did hang on exit while restoring the terminal configuration when it was started as a background job, for example using restic ... &. This has been fixed by only restoring the terminal configuration when restic is interrupted while reading a password from the terminal.

https://github.com/restic/restic/issues/2298
Bugfix #2389: Fix mangled json output of backup command

We've fixed a race condition in the json output of the backup command that could cause multiple lines to get mixed up. We've also ensured that the backup summary is printed last.

https://github.com/restic/restic/issues/2389 https://github.com/restic/restic/pull/2545
Bugfix #2390: Refresh lock timestamp

Long-running operations did not refresh lock timestamp, resulting in locks becoming stale. This is now fixed.

https://github.com/restic/restic/issues/2390
Bugfix #2429: Backup --json reports total_bytes_processed as 0

We've fixed the json output of total_bytes_processed. The non-json output was already fixed with pull request #2138 but left the json output untouched.

https://github.com/restic/restic/issues/2429
Bugfix #2469: Fix incorrect bytes stats in diff command

In some cases, the wrong number of bytes (e.g. 16777215.998 TiB) were reported by the diff command. This is now fixed.

https://github.com/restic/restic/issues/2469
Bugfix #2518: Do not crash with Synology NAS sftp server

It was found that when restic is used to store data on an sftp server on a Synology NAS with a relative path (one which does not start with a slash), it may go into an endless loop trying to create directories on the server. We've fixed this bug by using a function in the sftp library instead of our own implementation.

The bug was discovered because the Synology sftp server behaves erratic with non-absolute path (e.g. home/restic-repo). This can be resolved by just using an absolute path instead (/home/restic-repo). We've also added a paragraph in the FAQ.

https://github.com/restic/restic/issues/2518 https://github.com/restic/restic/issues/2363 https://github.com/restic/restic/pull/2530
Bugfix #2531: Fix incorrect size calculation in stats --mode restore-size

The restore-size mode of stats was counting hard-linked files as if they were independent.

https://github.com/restic/restic/issues/2531
Bugfix #2537: Fix incorrect file counts in stats --mode restore-size

The restore-size mode of stats was failing to count empty directories and some files with hard links.

https://github.com/restic/restic/issues/2537
Bugfix #2592: SFTP backend supports IPv6 addresses

The SFTP backend now supports IPv6 addresses natively, without relying on aliases in the external SSH configuration.

https://github.com/restic/restic/pull/2592
Bugfix #2607: Honor RESTIC_CACHE_DIR environment variable on Mac and Windows

On Mac and Windows, the RESTIC_CACHE_DIR environment variable was ignored. This variable can now be used on all platforms to set the directory where restic stores caches.

https://github.com/restic/restic/pull/2607
Bugfix #2668: Don't abort the stats command when data blobs are missing

Runing the stats command in the blobs-per-file mode on a repository with missing data blobs previously resulted in a crash.

https://github.com/restic/restic/pull/2668
Bugfix #2674: Add stricter prune error checks

Additional checks were added to the prune command in order to improve resiliency to backend, hardware and/or networking issues. The checks now detect a few more cases where such outside factors could potentially cause data loss.

https://github.com/restic/restic/pull/2674
Bugfix #2899: Fix possible crash in the progress bar of check --read-data

We've fixed a possible crash while displaying the progress bar for the check --read-data command. The crash occurred when the length of the progress bar status exceeded the terminal width, which only happened for very narrow terminal windows.

https://github.com/restic/restic/pull/2899 https://forum.restic.net/t/restic-rclone-pcloud-connection-issues/2963/15
Change #2482: Remove vendored dependencies

We've removed the vendored dependencies (in the subdir vendor/). When building restic, the Go compiler automatically fetches the dependencies. It will also cryptographically verify that the correct code has been fetched by using the hashes in go.sum (see the link to the documentation below).

https://github.com/restic/restic/issues/2482 https://golang.org/cmd/go/#hdr-Module_downloading_and_verification
Change #2546: Return exit code 3 when failing to backup all source data

The backup command used to return a zero exit code as long as a snapshot could be created successfully, even if some of the source files could not be read (in which case the snapshot would contain the rest of the files).

This made it hard for automation/scripts to detect failures/incomplete backups by looking at the exit code. Restic now returns the following exit codes for the backup command:
- 0 when the command was successful - 1 when there was a fatal error (no snapshot created) - 3 when some source data could not be read (incomplete snapshot created)
https://github.com/restic/restic/issues/956 https://github.com/restic/restic/issues/2064 https://github.com/restic/restic/issues/2526 https://github.com/restic/restic/issues/2364 https://github.com/restic/restic/pull/2546
Change #2600: Update dependencies, require Go >= 1.13

Restic now requires Go to be at least 1.13. This allows simplifications in the build process and removing workarounds.

This is also probably the last version of restic still supporting mounting repositories via fuse on macOS. The library we're using for fuse does not support macOS any more and osxfuse is not open source any more.

https://github.com/bazil/fuse/issues/224 https://github.com/osxfuse/osxfuse/issues/590 https://github.com/restic/restic/pull/2600 https://github.com/restic/restic/pull/2852 https://github.com/restic/restic/pull/2927
Change #1597: Honor the --no-lock flag in the mount command

The mount command now does not lock the repository if given the --no-lock flag. This allows to mount repositories which are archived on a read only backend/filesystem.

https://github.com/restic/restic/issues/1597 https://github.com/restic/restic/pull/2821
Enhancement #1570: Support specifying multiple host flags for various commands

Previously commands didn't take more than one --host or -H argument into account, which could be limiting with e.g. the forget command.

The dump, find, forget, ls, mount, restore, snapshots, stats and tag commands will now take into account multiple --host and -H flags.

https://github.com/restic/restic/issues/1570
Enhancement #1680: Optimize restic mount

We've optimized the FUSE implementation used within restic. restic mount is now more responsive and uses less memory.

https://github.com/restic/restic/issues/1680 https://github.com/restic/restic/pull/2587 https://github.com/restic/restic/pull/2787
Enhancement #2072: Display snapshot date when using restic find

Added the respective snapshot date to the output of restic find.

https://github.com/restic/restic/issues/2072
Enhancement #2175: Allow specifying user and host when creating keys

When adding a new key to the repository, the username and hostname for the new key can be specified on the command line. This allows overriding the defaults, for example if you would prefer to use the FQDN to identify the host or if you want to add keys for several different hosts without having to run the key add command on those hosts.

https://github.com/restic/restic/issues/2175
Enhancement #2277: Add support for ppc64le

Adds support for ppc64le, the processor architecture from IBM.

https://github.com/restic/restic/issues/2277
Enhancement #2395: Ignore sync errors when operation not supported by local filesystem

The local backend has been modified to work with filesystems which doesn't support the sync operation. This operation is normally used by restic to ensure that data files are fully written to disk before continuing.

For these limited filesystems, saving a file in the backend would previously fail with an "operation not supported" error. This error is now ignored, which means that e.g. an SMB mount on macOS can now be used as storage location for a repository.

https://github.com/restic/restic/issues/2395 https://forum.restic.net/t/sync-errors-on-mac-over-smb/1859
Enhancement #2427: Add flag --iexclude-file to backup command

The backup command now supports the flag --iexclude-file which is a case-insensitive version of --exclude-file.

https://github.com/restic/restic/issues/2427 https://github.com/restic/restic/pull/2898
Enhancement #2569: Support excluding files by their size

The backup command now supports the --exclude-larger-than option to exclude files which are larger than the specified maximum size. This can for example be useful to exclude unimportant files with a large file size.

https://github.com/restic/restic/issues/2569 https://github.com/restic/restic/pull/2914
Enhancement #2571: Self-heal missing file parts during backup of unchanged files

We've improved the resilience of restic to certain types of repository corruption.

For files that are unchanged since the parent snapshot, the backup command now verifies that all parts of the files still exist in the repository. Parts that are missing, e.g. from a damaged repository, are backed up again. This verification was already run for files that were modified since the parent snapshot, but is now also done for unchanged files.

Note that restic will not backup file parts that are referenced in the index but where the actual data is not present on disk, as this situation can only be detected by restic check. Please ensure that you run restic check regularly.

https://github.com/restic/restic/issues/2571 https://github.com/restic/restic/pull/2827
Enhancement #2858: Support filtering snapshots by tag and path in the stats command

We've added filtering snapshots by --tag tagList and by --path path to the stats command. This includes filtering of only 'latest' snapshots or all snapshots in a repository.

https://github.com/restic/restic/issues/2858 https://github.com/restic/restic/pull/2859 https://forum.restic.net/t/stats-for-a-host-and-filtered-snapshots/3020
Enhancement #323: Add command for copying snapshots between repositories

We've added a copy command, allowing you to copy snapshots from one repository to another.

Note that this process will have to read (download) and write (upload) the entire snapshot(s) due to the different encryption keys used on the source and destination repository. Also, the transferred files are not re-chunked, which may break deduplication between files already stored in the destination repo and files copied there using this command.

To fully support deduplication between repositories when the copy command is used, the init command now supports the --copy-chunker-params option, which initializes the new repository with identical parameters for splitting files into chunks as an already existing repository. This allows copied snapshots to be equally deduplicated in both repositories.

https://github.com/restic/restic/issues/323 https://github.com/restic/restic/pull/2606 https://github.com/restic/restic/pull/2928
Enhancement #551: Use optimized library for hash calculation of file chunks

We've switched the library used to calculate the hashes of file chunks, which are used for deduplication, to the optimized Minio SHA-256 implementation.

Depending on the CPU it improves the hashing throughput by 10-30%. Modern x86 CPUs with the SHA Extension should be about two to three times faster.

https://github.com/restic/restic/issues/551 https://github.com/restic/restic/pull/2709
Enhancement #2195: Simplify and improve restore performance

Significantly improves restore performance of large files (i.e. 50M+): https://github.com/restic/restic/issues/2074 https://forum.restic.net/t/restore-using-rclone-gdrive-backend-is-slow/1112/8 https://forum.restic.net/t/degraded-restore-performance-s3-backend/1400

Fixes "not enough cache capacity" error during restore: https://github.com/restic/restic/issues/2244

NOTE: This new implementation does not guarantee order in which blobs are written to the target files and, for example, the last blob of a file can be written to the file before any of the preceeding file blobs. It is therefore possible to have gaps in the data written to the target files if restore fails or interrupted by the user.

The implementation will try to preallocate space for the restored files on the filesystem to prevent file fragmentation. This ensures good read performance for large files, like for example VM images. If preallocating space is not supported by the filesystem, then this step is silently skipped.

https://github.com/restic/restic/pull/2195 https://github.com/restic/restic/pull/2893
Enhancement #2328: Improve speed of check command

We've improved the check command to traverse trees only once independent of whether they are contained in multiple snapshots. The check command is now much faster for repositories with a large number of snapshots.

https://github.com/restic/restic/issues/2284 https://github.com/restic/restic/pull/2328
Enhancement #2423: Support user@domain parsing as user

Added the ability for user@domain-like users to be authenticated over SFTP servers.

https://github.com/restic/restic/pull/2423
Enhancement #2576: Improve the chunking algorithm

We've updated the chunker library responsible for splitting files into smaller blocks. It should improve the chunking throughput by 5-15% depending on the CPU.

https://github.com/restic/restic/issues/2820 https://github.com/restic/restic/pull/2576 https://github.com/restic/restic/pull/2845
Enhancement #2598: Improve speed of diff command

We've improved the performance of the diff command when comparing snapshots with similar content. It should run up to twice as fast as before.

https://github.com/restic/restic/pull/2598
Enhancement #2599: Slightly reduce memory usage of prune and stats commands

The prune and the stats command kept directory identifiers in memory twice while searching for used blobs.

https://github.com/restic/restic/pull/2599
Enhancement #2733: S3 backend: Add support for WebIdentityTokenFile

We've added support for EKS IAM roles for service accounts feature to the S3 backend.

https://github.com/restic/restic/issues/2703 https://github.com/restic/restic/pull/2733
Enhancement #2773: Optimize handling of new index entries

Restic now uses less memory for backups which add a lot of data, e.g. large initial backups. In addition, we've improved the stability in some edge cases.

https://github.com/restic/restic/pull/2773
Enhancement #2781: Reduce memory consumption of in-memory index

We've improved how the index is stored in memory. This change can reduce memory usage for large repositories by up to 50% (depending on the operation).

https://github.com/restic/restic/pull/2781 https://github.com/restic/restic/pull/2812
Enhancement #2786: Optimize list blobs command

We've changed the implementation of list blobs which should be now a bit faster and consume almost no memory even for large repositories.

https://github.com/restic/restic/pull/2786
Enhancement #2790: Optimized file access in restic mount

Reading large (> 100GiB) files from restic mountpoints is now faster, and the speedup is greater for larger files.

https://github.com/restic/restic/pull/2790
Enhancement #2840: Speed-up file deletion in forget, prune and rebuild-index

We've sped up the file deletion for the commands forget, prune and rebuild-index, especially for remote repositories. Deletion was sequential before and is now run in parallel.

https://github.com/restic/restic/pull/2840

Changelog for restic 0.9.6 (2019-11-22)

The following sections list the changes in restic 0.9.6 relevant to restic users. The changes are ordered by importance.

Summary

Fix #2063: Allow absolute path for filename when backing up from stdin
Fix #2174: Save files with invalid timestamps
Fix #2249: Read fresh metadata for unmodified files
Fix #2301: Add upper bound for t in --read-data-subset=n/t
Fix #2321: Check errors when loading index files
Enh #2179: Use ctime when checking for file changes
Enh #2306: Allow multiple retries for interactive password input
Enh #2330: Make --group-by accept both singular and plural
Enh #2350: Add option to configure S3 region

Details

Bugfix #2063: Allow absolute path for filename when backing up from stdin

When backing up from stdin, handle directory path for --stdin-filename. This can be used to specify the full path for the backed-up file.

https://github.com/restic/restic/issues/2063
Bugfix #2174: Save files with invalid timestamps

When restic reads invalid timestamps (year is before 0000 or after 9999) it refused to read and archive the file. We've changed the behavior and will now save modified timestamps with the year set to either 0000 or 9999, the rest of the timestamp stays the same, so the file will be saved (albeit with a bogus timestamp).

https://github.com/restic/restic/issues/2174 https://github.com/restic/restic/issues/1173
Bugfix #2249: Read fresh metadata for unmodified files

Restic took all metadata for files which were detected as unmodified, not taking into account changed metadata (ownership, mode). This is now corrected.

https://github.com/restic/restic/issues/2249 https://github.com/restic/restic/pull/2252
Bugfix #2301: Add upper bound for t in --read-data-subset=n/t

256 is the effective maximum for t, but restic would allow larger values, leading to strange behavior.

https://github.com/restic/restic/issues/2301 https://github.com/restic/restic/pull/2304
Bugfix #2321: Check errors when loading index files

Restic now checks and handles errors which occur when loading index files, the missing check leads to odd errors (and a stack trace printed to users) later. This was reported in the forum.

https://github.com/restic/restic/pull/2321 https://forum.restic.net/t/check-rebuild-index-prune/1848/13
Enhancement #2179: Use ctime when checking for file changes

Previously, restic only checked a file's mtime (along with other non-timestamp metadata) to decide if a file has changed. This could cause restic to not notice that a file has changed (and therefore continue to store the old version, as opposed to the modified version) if something edits the file and then resets the timestamp. Restic now also checks the ctime of files, so any modifications to a file should be noticed, and the modified file will be backed up. The ctime check will be disabled if the --ignore-inode flag was given.

If this change causes problems for you, please open an issue, and we can look in to adding a seperate flag to disable just the ctime check.

https://github.com/restic/restic/issues/2179 https://github.com/restic/restic/pull/2212
Enhancement #2306: Allow multiple retries for interactive password input

Restic used to quit if the repository password was typed incorrectly once. Restic will now ask the user again for the repository password if typed incorrectly. The user will now get three tries to input the correct password before restic quits.

https://github.com/restic/restic/issues/2306
Enhancement #2330: Make --group-by accept both singular and plural

One can now use the values host/hosts, path/paths and tag / tags interchangeably in the --group-by argument.

https://github.com/restic/restic/issues/2330
Enhancement #2350: Add option to configure S3 region

We've added a new option for setting the region when accessing an S3-compatible service. For some providers, it is required to set this to a valid value. You can do that either by setting the environment variable AWS_DEFAULT_REGION or using the option s3.region, e.g. like this: -o s3.region="us-east-1".

https://github.com/restic/restic/pull/2350

Changelog for restic 0.9.5 (2019-04-23)

The following sections list the changes in restic 0.9.5 relevant to restic users. The changes are ordered by importance.

Summary

Fix #2135: Return error when no bytes could be read from stdin
Fix #2181: Don't cancel timeout after 30 seconds for self-update
Fix #2203: Fix reading passwords from stdin
Fix #2224: Don't abort the find command when a tree can't be loaded
Enh #1895: Add case insensitive include & exclude options
Enh #1937: Support streaming JSON output for backup
Enh #2155: Add Openstack application credential auth for Swift

Enh #2139: Return error if no bytes could be read for backup --stdin
Enh #2205: Add --ignore-inode option to backup cmd
Enh #2220: Add config option to set S3 storage class

Details

Bugfix #2135: Return error when no bytes could be read from stdin

We assume that users reading backup data from stdin want to know when no data could be read, so now restic returns an error when backup --stdin is called but no bytes could be read. Usually, this means that an earlier command in a pipe has failed. The documentation was amended and now recommends setting the pipefail option (set -o pipefail).

https://github.com/restic/restic/pull/2135 https://github.com/restic/restic/pull/2139
Bugfix #2181: Don't cancel timeout after 30 seconds for self-update

https://github.com/restic/restic/issues/2181
Bugfix #2203: Fix reading passwords from stdin

Passwords for the init, key add, and key passwd commands can now be read from non-terminal stdin.

https://github.com/restic/restic/issues/2203
Bugfix #2224: Don't abort the find command when a tree can't be loaded

Change the find command so that missing trees don't result in a crash. Instead, the error is logged to the debug log, and the tree ID is displayed along with the snapshot it belongs to. This makes it possible to recover repositories that are missing trees by forgetting the snapshots they are used in.

https://github.com/restic/restic/issues/2224
Enhancement #1895: Add case insensitive include & exclude options

The backup and restore commands now have --iexclude and --iinclude flags as case insensitive variants of --exclude and --include.

https://github.com/restic/restic/issues/1895 https://github.com/restic/restic/pull/2032
Enhancement #1937: Support streaming JSON output for backup

We've added support for getting machine-readable status output during backup, just pass the flag --json for restic backup and restic will output a stream of JSON objects which contain the current progress.

https://github.com/restic/restic/issues/1937 https://github.com/restic/restic/pull/1944
Enhancement #2155: Add Openstack application credential auth for Swift

Since Openstack Queens Identity (auth V3) service supports an application credential auth method. It allows to create a technical account with the limited roles. This commit adds an application credential authentication method for the Swift backend.

https://github.com/restic/restic/issues/2155
Enhancement #2184: Add --json support to forget command

The forget command now supports the --json argument, outputting the information about what is (or would-be) kept and removed from the repository.

https://github.com/restic/restic/issues/2184 https://github.com/restic/restic/pull/2185
Enhancement #2037: Add group-by option to snapshots command

We have added an option to group the output of the snapshots command, similar to the output of the forget command. The option has been called "--group-by" and accepts any combination of the values "host", "paths" and "tags", separated by commas. Default behavior (not specifying --group-by) has not been changed. We have added support of the grouping to the JSON output.

https://github.com/restic/restic/issues/2037 https://github.com/restic/restic/pull/2087
Enhancement #2124: Ability to dump folders to tar via stdout

We've added the ability to dump whole folders to stdout via the dump command. Restic now requires at least Go 1.10 due to a limitation of the standard library for Go <= 1.9.

https://github.com/restic/restic/issues/2123 https://github.com/restic/restic/pull/2124
Enhancement #2139: Return error if no bytes could be read for backup --stdin

When restic is used to backup the output of a program, like mysqldump | restic backup --stdin, it now returns an error if no bytes could be read at all. This catches the failure case when mysqldump failed for some reason and did not output any data to stdout.

Enhancement #2205: Add --ignore-inode option to backup cmd

This option handles backup of virtual filesystems that do not keep fixed inodes for files, like Fuse-based, pCloud, etc. Ignoring inode changes allows to consider the file as unchanged if last modification date and size are unchanged.

https://github.com/restic/restic/issues/1631 https://github.com/restic/restic/pull/2205 https://github.com/restic/restic/pull/2047
Enhancement #2220: Add config option to set S3 storage class

The s3.storage-class option can be passed to restic (using -o) to specify the storage class to be used for S3 objects created by restic.

The storage class is passed as-is to S3, so it needs to be understood by the API. On AWS, it can be one of STANDARD, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING and REDUCED_REDUNDANCY. If unspecified, the default storage class is used (STANDARD on AWS).

You can mix storage classes in the same bucket, and the setting isn't stored in the restic repository, so be sure to specify it with each command that writes to S3.

Details

Bugfix #1989: Google Cloud Storage: Respect bandwidth limit

The GCS backend did not respect the bandwidth limit configured, a previous commit accidentally removed support for it.

https://github.com/restic/restic/issues/1989 https://github.com/restic/restic/pull/2100
Bugfix #2040: Add host name filter shorthand flag for stats command

The default value for --host flag was set to 'H' (the shorthand version of the flag), this caused the lookup for the latest snapshot to fail.

Add shorthand flag -H for --host (with empty default so if these flags are not specified the latest snapshot will not filter by host name).

Also add shorthand -H for backup command.

https://github.com/restic/restic/issues/2040
Bugfix #2068: Correctly return error loading data

In one case during prune and check, an error loading data from the backend is not returned properly. This is now corrected.

https://github.com/restic/restic/issues/1999#issuecomment-433737921 https://github.com/restic/restic/pull/2068
Bugfix #2095: Consistently use local time for snapshots times

By default snapshots created with restic backup were set to local time, but when the --time flag was used the provided timestamp was parsed as UTC. With this change all snapshots times are set to local time.

https://github.com/restic/restic/pull/2095
Enhancement #1605: Concurrent restore

This change significantly improves restore performance, especially when using high-latency remote repositories like B2.

The implementation now uses several concurrent threads to download and process multiple remote files concurrently. To further reduce restore time, each remote file is downloaded using a single repository request.

https://github.com/restic/restic/issues/1605 https://github.com/restic/restic/pull/1719
Enhancement #2089: Increase granularity of the "keep within" retention policy

The keep-within option of the forget command now accepts time ranges with an hourly granularity. For example, running restic forget --keep-within 3d12h will keep all the snapshots made within three days and twelve hours from the time of the latest snapshot.

https://github.com/restic/restic/issues/2089 https://github.com/restic/restic/pull/2090
Enhancement #2097: Add key hinting

Added a new option --key-hint and corresponding environment variable RESTIC_KEY_HINT. The key hint is a key ID to try decrypting first, before other keys in the repository.

This change will benefit repositories with many keys; if the correct key hint is supplied then restic only needs to check one key. If the key hint is incorrect (the key does not exist, or the password is incorrect) then restic will check all keys, as usual.

https://github.com/restic/restic/issues/2097
Enhancement #2017: Mount: Enforce FUSE Unix permissions with allow-other

The fuse mount (restic mount) now lets the kernel check the permissions of the files within snapshots (this is done through the DefaultPermissions FUSE option) when the option --allow-other is specified.

To restore the old behavior, we've added the --no-default-permissions option. This allows all users that have access to the mount point to access all files within the snapshots.

https://github.com/restic/restic/pull/2017
Enhancement #2070: Make all commands display timestamps in local time

Restic used to drop the timezone information from displayed timestamps, it now converts timestamps to local time before printing them so the times can be easily compared to.

https://github.com/restic/restic/pull/2070
Enhancement #2085: Allow --files-from to be specified multiple times

Before, restic took only the last file specified with --files-from into account, this is now corrected.

https://github.com/restic/restic/issues/2085 https://github.com/restic/restic/pull/2086
Enhancement #2094: Run command to get password

We've added the --password-command option which allows specifying a command that restic runs every time the password for the repository is needed, so it can be integrated with a password manager or keyring. The option can also be set via the environment variable $RESTIC_PASSWORD_COMMAND.

https://github.com/restic/restic/pull/2094

Details

Bugfix #1935: Remove truncated files from cache

When a file in the local cache is truncated, and restic tries to access data beyond the end of the (cached) file, it used to return an error "EOF". This is now fixed, such truncated files are removed and the data is fetched directly from the backend.

https://github.com/restic/restic/issues/1935
Bugfix #1978: Do not return an error when the scanner is slower than backup

When restic makes a backup, there's a background task called "scanner" which collects information on how many files and directories are to be saved, in order to display progress information to the user. When the backup finishes faster than the scanner, it is aborted because the result is not needed any more. This logic contained a bug, where quitting the scanner process was treated as an error, and caused restic to print an unhelpful error message ("context canceled").

https://github.com/restic/restic/issues/1978 https://github.com/restic/restic/pull/1991
Enhancement #1766: Restore: suppress lchown errors when not running as root

Like "cp" and "rsync" do, restic now only reports errors for changing the ownership of files during restore if it is run as root, on non-Windows operating systems. On Windows, the error is reported as usual.

https://github.com/restic/restic/issues/1766
Enhancement #1909: Reject files/dirs by name first

The current scanner/archiver code had an architectural limitation: it always ran the lstat() system call on all files and directories before a decision to include/exclude the file/dir was made. This lead to a lot of unnecessary system calls for items that could have been rejected by their name or path only.

We've changed the archiver/scanner implementation so that it now first rejects by name/path, and only runs the system call on the remaining items. This reduces the number of lstat() system calls a lot (depending on the exclude settings).

https://github.com/restic/restic/issues/1909 https://github.com/restic/restic/pull/1912
Enhancement #1940: Add directory filter to ls command

The ls command can now be filtered by directories, so that only files in the given directories will be shown. If the --recursive flag is specified, then ls will traverse subfolders and list their files as well.

It used to be possible to specify multiple snapshots, but that has been replaced by only one snapshot and the possibility of specifying multiple directories.

Specifying directories constrains the walk, which can significantly speed up the listing.

https://github.com/restic/restic/issues/1940 https://github.com/restic/restic/pull/1941
Enhancement #1967: Use --host everywhere

We now use the flag --host for all commands which need a host name, using --hostname (e.g. for restic backup) still works, but will print a deprecation warning. Also, add the short option -H where possible.

https://github.com/restic/restic/issues/1967
Enhancement #2028: Display size of cache directories

The cache command now by default shows the size of the individual cache directories. It can be disabled with --no-size.

https://github.com/restic/restic/issues/2028 https://github.com/restic/restic/pull/2033
Enhancement #1777: Improve the find command

We've updated the find command to support multiple patterns.

restic find is now able to list the snapshots containing a specific tree or blob, or even the snapshots that contain blobs belonging to a given pack. A list of IDs can be given, as long as they all have the same type.

The command find can also display the pack IDs the blobs belong to, if the --show-pack-id flag is provided.

https://github.com/restic/restic/issues/1777 https://github.com/restic/restic/pull/1780
Enhancement #1876: Display reason why forget keeps snapshots

We've added a column to the list of snapshots forget keeps which details the reasons to keep a particuliar snapshot. This makes debugging policies for forget much easier. Please remember to always try things out with --dry-run!

https://github.com/restic/restic/pull/1876
Enhancement #1891: Accept glob in paths loaded via --files-from

Before that, behaviour was different if paths were appended to command line or from a file, because wild card characters were expanded by shell if appended to command line, but not expanded if loaded from file.

https://github.com/restic/restic/issues/1891
Enhancement #1920: Vendor dependencies with Go 1.11 Modules

Until now, we've used dep for managing dependencies, we've now switch to using Go modules. For users this does not change much, only if you want to compile restic without downloading anything with Go 1.11, then you need to run: go build -mod=vendor build.go

https://github.com/restic/restic/pull/1920
Enhancement #1949: Add new command self-update

We have added a new command called self-update which downloads the latest released version of restic from GitHub and replaces the current binary with it. It does not rely on any external program (so it'll work everywhere), but still verifies the GPG signature using the embedded GPG public key.

By default, the self-update command is hidden behind the selfupdate built tag, which is only set when restic is built using build.go (including official releases). The reason for this is that downstream distributions will then not include the command by default, so users are encouraged to use the platform-specific distribution mechanism.

https://github.com/restic/restic/pull/1949
Enhancement #1953: Ls: Add JSON output support for restic ls cmd

We've implemented listing files in the repository with JSON as output, just pass --json as an option to restic ls. This makes the output of the command machine readable.

https://github.com/restic/restic/pull/1953
Enhancement #1962: Stream JSON output for ls command

The ls command now supports JSON output with the global --json flag, and this change streams out JSON messages one object at a time rather than en entire array buffered in memory before encoding. The advantage is it allows large listings to be handled efficiently.

Two message types are printed: snapshots and nodes. A snapshot object will precede node objects which belong to that snapshot. The struct_type field can be used to determine which kind of message an object is.

Details

Bugfix #1854: Allow saving files/dirs on different fs with --one-file-system

Restic now allows saving files/dirs on a different file system in a subdir correctly even when --one-file-system is specified.

The first thing the restic archiver code does is to build a tree of the target files/directories. If it detects that a parent directory is already included (e.g. restic backup /foo /foo/bar/baz), it'll ignore the latter argument.

Without --one-file-system, that's perfectly valid: If /foo is to be archived, it will include /foo/bar/baz. But with --one-file-system, /foo/bar/baz may reside on a different file system, so it won't be included with /foo.

https://github.com/restic/restic/issues/1854 https://github.com/restic/restic/pull/1855
Bugfix #1870: Fix restore with --include

We fixed a bug which prevented restic to restore files with an include filter.

https://github.com/restic/restic/issues/1870 https://github.com/restic/restic/pull/1900
Bugfix #1880: Use --cache-dir argument for check command

check command now uses a temporary sub-directory of the specified directory if set using the --cache-dir argument. If not set, the cache directory is created in the default temporary directory as before. In either case a temporary cache is used to ensure the actual repository is checked (rather than a local copy).

The --cache-dir argument was not used by the check command, instead a cache directory was created in the temporary directory.

https://github.com/restic/restic/issues/1880
Bugfix #1893: Return error when exclude file cannot be read

A bug was found: when multiple exclude files were passed to restic and one of them could not be read, an error was printed and restic continued, ignoring even the existing exclude files. Now, an error message is printed and restic aborts when an exclude file cannot be read.

https://github.com/restic/restic/issues/1893
Bugfix #1861: Fix case-insensitive search with restic find

We've fixed the behavior for restic find -i PATTERN, which was broken in v0.9.1.

https://github.com/restic/restic/pull/1861
Enhancement #1906: Add support for B2 application keys

Restic can now use so-called "application keys" which can be created in the B2 dashboard and were only introduced recently. In contrast to the "master key", such keys can be restricted to a specific bucket and/or path.

https://github.com/restic/restic/issues/1906 https://github.com/restic/restic/pull/1914
Enhancement #874: Add stats command to get information about a repository

https://github.com/restic/restic/issues/874 https://github.com/restic/restic/pull/1729
Enhancement #1772: Add restore --verify to verify restored file content

Restore will print error message if restored file content does not match expected SHA256 checksum

https://github.com/restic/restic/pull/1772
Enhancement #1853: Add JSON output support to restic key list

This PR enables users to get the output of restic key list in JSON in addition to the existing table format.

https://github.com/restic/restic/pull/1853
Enhancement #1477: S3 backend: accept AWS_SESSION_TOKEN

Before, it was not possible to use s3 backend with AWS temporary security credentials(with AWS_SESSION_TOKEN). This change gives higher priority to credentials.EnvAWS credentials provider.

https://github.com/restic/restic/issues/1477 https://github.com/restic/restic/pull/1479 https://github.com/restic/restic/pull/1647
Enhancement #1901: Update the Backblaze B2 library

We've updated the library we're using for accessing the Backblaze B2 service to 0.5.0 to include support for upcoming so-called "application keys". With this feature, you can create access credentials for B2 which are restricted to e.g. a single bucket or even a sub-directory of a bucket.

Changelog for restic 0.9.1 (2018-06-10)

The following sections list the changes in restic 0.9.1 relevant to restic users. The changes are ordered by importance.

Summary

Fix #1801: Add limiting bandwidth to the rclone backend
Fix #1822: Allow uploading large files to MS Azure
Fix #1825: Correct find to not skip snapshots
Fix #1833: Fix caching files on error
Fix #1834: Resolve deadlock

Details

Bugfix #1801: Add limiting bandwidth to the rclone backend

The rclone backend did not respect --limit-upload or --limit-download. Oftentimes it's not necessary to use this, as the limiting in rclone itself should be used because it gives much better results, but in case a remote instance of rclone is used (e.g. called via ssh), it is still relevant to limit the bandwidth from restic to rclone.

https://github.com/restic/restic/issues/1801
Bugfix #1822: Allow uploading large files to MS Azure

Sometimes, restic creates files to be uploaded to the repository which are quite large, e.g. when saving directories with many entries or very large files. The MS Azure API does not allow uploading files larger that 256MiB directly, rather restic needs to upload them in blocks of 100MiB. This is now implemented.

https://github.com/restic/restic/issues/1822
Bugfix #1825: Correct find to not skip snapshots

Under certain circumstances, the find command was found to skip snapshots containing directories with files to look for when the directories haven't been modified at all, and were already printed as part of a different snapshot. This is now corrected.

In addition, we've switched to our own matching/pattern implementation, so now things like restic find "/home/user/foo/**/main.go" are possible.

https://github.com/restic/restic/issues/1825 https://github.com/restic/restic/issues/1823
Bugfix #1833: Fix caching files on error

During check it may happen that different threads access the same file in the backend, which is then downloaded into the cache only once. When that fails, only the thread which is responsible for downloading the file signals the correct error. The other threads just assume that the file has been downloaded successfully and then get an error when they try to access the cached file.

https://github.com/restic/restic/issues/1833
Bugfix #1834: Resolve deadlock

When the "scanning" process restic runs to find out how much data there is does not finish before the backup itself is done, restic stops doing anything. This is resolved now.

Details

Bugfix #1608: Respect time stamp for new backup when reading from stdin

When reading backups from stdin (via restic backup --stdin), restic now uses the time stamp for the new backup passed in --time.

https://github.com/restic/restic/issues/1608 https://github.com/restic/restic/pull/1703
Bugfix #1652: Ignore/remove invalid lock files

This corrects a bug introduced recently: When an invalid lock file in the repo is encountered (e.g. if the file is empty), the code used to ignore that, but now returns the error. Now, invalid files are ignored for the normal lock check, and removed when restic unlock --remove-all is run.

https://github.com/restic/restic/issues/1652 https://github.com/restic/restic/pull/1653
Bugfix #1730: Ignore sockets for restore

We've received a report and correct the behavior in which the restore code aborted restoring a directory when a socket was encountered. Unix domain socket files cannot be restored (they are created on the fly once a process starts listening). The error handling was corrected, and in addition we're now ignoring sockets during restore.

https://github.com/restic/restic/issues/1730 https://github.com/restic/restic/pull/1731
Bugfix #1684: Fix backend tests for rest-server

The REST server for restic now requires an explicit parameter (--no-auth) if no authentication should be allowed. This is fixed in the tests.

https://github.com/restic/restic/pull/1684
Bugfix #1745: Correctly parse the argument to --tls-client-cert

Previously, the --tls-client-cert method attempt to read ARGV[1] (hardcoded) instead of the argument that was passed to it. This has been corrected.

https://github.com/restic/restic/issues/1745 https://github.com/restic/restic/pull/1746
Enhancement #1433: Support UTF-16 encoding and process Byte Order Mark

On Windows, text editors commonly leave a Byte Order Mark at the beginning of the file to define which encoding is used (oftentimes UTF-16). We've added code to support processing the BOMs in text files, like the exclude files, the password file and the file passed via --files-from. This does not apply to any file being saved in a backup, those are not touched and archived as they are.

https://github.com/restic/restic/issues/1433 https://github.com/restic/restic/issues/1738 https://github.com/restic/restic/pull/1748
Enhancement #1561: Allow using rclone to access other services

We've added the ability to use rclone to store backup data on all backends that it supports. This was done in collaboration with Nick, the author of rclone. You can now use it to first configure a service, then restic manages the rest (starting and stopping rclone). For details, please see the manual.

https://github.com/restic/restic/issues/1561 https://github.com/restic/restic/pull/1657 https://rclone.org
Enhancement #1665: Improve cache handling for restic check

For safety reasons, restic does not use a local metadata cache for the restic check command, so that data is loaded from the repository and restic can check it's in good condition. When the cache is disabled, restic will fetch each tiny blob needed for checking the integrity using a separate backend request. For non-local backends, that will take a long time, and depending on the backend (e.g. B2) may also be much more expensive.

This PR adds a few commits which will change the behavior as follows:
- When restic check is called without any additional parameters, it will build a new cache in a temporary directory, which is removed at the end of the check. This way, we'll get readahead for metadata files (so restic will fetch the whole file when the first blob from the file is requested), but all data is freshly fetched from the storage backend. This is the default behavior and will work for almost all users.
- When restic check is called with --with-cache, the default on-disc cache is used. This behavior hasn't changed since the cache was introduced.
- When --no-cache is specified, restic falls back to the old behavior, and read all tiny blobs in separate requests.
https://github.com/restic/restic/issues/1665 https://github.com/restic/restic/issues/1694 https://github.com/restic/restic/pull/1696
Enhancement #1721: Add cache command to list cache dirs

The command cache was added, it allows listing restic's cache directoriers together with the last usage. It also allows removing old cache dirs without having to access a repo, via restic cache --cleanup

https://github.com/restic/restic/issues/1721 https://github.com/restic/restic/pull/1749
Enhancement #1758: Allow saving OneDrive folders in Windows

Restic now contains a bugfix to two libraries, which allows saving OneDrive folders in Windows. In order to use the newer versions of the libraries, the minimal version required to compile restic is now Go 1.9.

https://github.com/restic/restic/issues/1758 https://github.com/restic/restic/pull/1765
Enhancement #549: Rework archiver code

The core archiver code and the complementary code for the backup command was rewritten completely. This resolves very annoying issues such as 549. The first backup with this release of restic will likely result in all files being re-read locally, so it will take a lot longer. The next backup after that will be fast again.

Basically, with the old code, restic took the last path component of each to-be-saved file or directory as the top-level file/directory within the snapshot. This meant that when called as restic backup /home/user/foo, the snapshot would contain the files in the directory /home/user/foo as /foo.

This is not the case any more with the new archiver code. Now, restic works very similar to what tar does: When restic is called with an absolute path to save, then it'll preserve the directory structure within the snapshot. For the example above, the snapshot would contain the files in the directory within /home/user/foo in the snapshot. For relative directories, it only preserves the relative path components. So restic backup user/foo will save the files as /user/foo in the snapshot.

While we were at it, the status display and notification system was completely rewritten. By default, restic now shows which files are currently read (unless --quiet is specified) in a multi-line status display.

The backup command also gained a new option: --verbose. It can be specified once (which prints a bit more detail what restic is doing) or twice (which prints a line for each file/directory restic encountered, together with some statistics).

Another issue that was resolved is the new code only reads two files at most. The old code would read way too many files in parallel, thereby slowing down the backup process on spinning discs a lot.

Enhancement #1552: Use Google Application Default credentials

Google provide libraries to generate appropriate credentials with various fallback sources. This change uses the library to generate our GCS client, which allows us to make use of these extra methods.

This should be backward compatible with previous restic behaviour while adding the additional capabilities to auth from Google's internal metadata endpoints. For users running restic in GCP this can make authentication far easier than it was before.

Enhancement #1477: Accept AWS_SESSION_TOKEN for the s3 backend

Before, it was not possible to use s3 backend with AWS temporary security credentials(with AWS_SESSION_TOKEN). This change gives higher priority to credentials.EnvAWS credentials provider.

https://github.com/restic/restic/issues/1477 https://github.com/restic/restic/pull/1479 https://github.com/restic/restic/pull/1647
Enhancement #1648: Ignore AWS permission denied error when creating a repository

It's not possible to use s3 backend scoped to a subdirectory(with specific permissions). Restic doesn't try to create repository in a subdirectory, when 'bucket exists' of parent directory check fails due to permission issues.

Enhancement #1649: Add illumos/Solaris support

https://github.com/restic/restic/pull/1649
Enhancement #1709: Improve messages restic check prints

Some messages restic check prints are not really errors, so from now on restic does not treat them as errors any more and exits cleanly.

Enhancement #1735: Allow keeping a time range of snaphots

We've added the --keep-within option to the forget command. It instructs restic to keep all snapshots within the given duration since the newest snapshot. For example, running restic forget --keep-within 5m7d will keep all snapshots which have been made in the five months and seven days since the latest snapshot.

https://github.com/restic/restic/pull/1735
Enhancement #1782: Use default AWS credentials chain for S3 backend

Adds support for file credentials to the S3 backend (e.g. ~/.aws/credentials), and reorders the credentials chain for the S3 backend to match AWS's standard, which is static credentials, env vars, credentials file, and finally remote.

Details

Bugfix #1633: Fixed unexpected 'pack file cannot be listed' error

Due to a regression introduced in 0.8.2, the rebuild-index and prune commands failed to read pack files with size of 587, 588, 589 or 590 bytes.

https://github.com/restic/restic/issues/1633 https://github.com/restic/restic/pull/1635
Bugfix #1641: Ignore files with invalid names in the repo

The release 0.8.2 introduced a bug: when restic encounters files in the repo which do not have a valid name, it tries to load a file with a name of lots of zeroes instead of ignoring it. This is now resolved, invalid file names are just ignored.

https://github.com/restic/restic/issues/1641 https://github.com/restic/restic/pull/1643 https://forum.restic.net/t/help-fixing-repo-no-such-file/485/3
Bugfix #1638: Handle errors listing files in the backend

A user reported in the forum that restic completes a backup although a concurrent prune operation was running. A few error messages were printed, but the backup was attempted and completed successfully. No error code was returned.

This should not happen: The repository is exclusively locked during prune, so when restic backup is run in parallel, it should abort and return an error code instead.

It was found that the bug was in the code introduced only recently, which retries a List() operation on the backend should that fail. It is now corrected.

https://github.com/restic/restic/pull/1638 https://forum.restic.net/t/restic-backup-returns-0-exit-code-when-already-locked/484
Enhancement #1497: Add --read-data-subset flag to check command

This change introduces ability to check integrity of a subset of repository data packs. This can be used to spread integrity check of larger repositories over a period of time.

https://github.com/restic/restic/issues/1497 https://github.com/restic/restic/pull/1556
Enhancement #1560: Retry all repository file download errors

Restic will now retry failed downloads, similar to other operations.

https://github.com/restic/restic/pull/1560
Enhancement #1623: Don't check for presence of files in the backend before writing

Before, all backend implementations were required to return an error if the file that is to be written already exists in the backend. For most backends, that means making a request (e.g. via HTTP) and returning an error when the file already exists.

This is not accurate, the file could have been created between the HTTP request testing for it, and when writing starts, so we've relaxed this requeriment, which saves one additional HTTP request per newly added file.

https://github.com/restic/restic/pull/1623
Enhancement #1634: Upgrade B2 client library, reduce HTTP requests

We've upgraded the B2 client library restic uses to access BackBlaze B2. This reduces the number of HTTP requests needed to upload a new file from two to one, which should improve throughput to B2.

https://github.com/restic/restic/pull/1634

Bugfix #1506: Limit bandwith at the http.RoundTripper for HTTP based backends

https://github.com/restic/restic/issues/1506 https://github.com/restic/restic/pull/1511
Bugfix #1512: Restore directory permissions as the last step

This change allows restoring into directories that were not writable during backup. Before, restic created the directory, set the read-only mode and then failed to create files in the directory. This change now restores the directory (with its permissions) as the very last step.

https://github.com/restic/restic/issues/1512 https://github.com/restic/restic/pull/1536
Bugfix #1528: Correctly create missing subdirs in data/

https://github.com/restic/restic/issues/1528 https://github.com/restic/restic/pull/1529
Bugfix #1590: Strip spaces for lines read via --files-from

Leading and trailing spaces in lines read via --files-from are now stripped, so it behaves the same as with lines read via --exclude-file.

https://github.com/restic/restic/issues/1590 https://github.com/restic/restic/pull/1613
Bugfix #1589: Complete intermediate index upload

After a user posted a comprehensive report of what he observed, we were able to find a bug and correct it: During backup, restic uploads so-called "intermediate" index files. When the backup finishes during a transfer of such an intermediate index, the upload is cancelled, but the backup is finished without an error. This leads to an inconsistent state, where the snapshot references data that is contained in the repo, but is not referenced in any index.

The situation can be resolved by building a new index with rebuild-index, but looks very confusing at first. Since all the data got uploaded to the repo successfully, there was no risk of data loss, just minor inconvenience for our users.

https://github.com/restic/restic/pull/1589 https://forum.restic.net/t/error-loading-tree-check-prune-and-forget-gives-error-b2-backend/406
Bugfix #1594: Google Cloud Storage: Use generic HTTP transport

It was discovered that the Google Cloud Storage backend did not use the generic HTTP transport, so things such as bandwidth limiting with --limit-upload did not work. This is resolved now.

https://github.com/restic/restic/pull/1594
Bugfix #1595: Backup: Remove bandwidth display

This commit removes the bandwidth displayed during backup process. It is misleading and seldomly correct, because it's neither the "read bandwidth" (only for the very first backup) nor the "upload bandwidth". Many users are confused about (and rightly so), c.f. #1581, #1033, #1591

We'll eventually replace this display with something more relevant when the new archiver code is ready.

https://github.com/restic/restic/pull/1595
Enhancement #1522: Add support for TLS client certificate authentication

Support has been added for using a TLS client certificate for authentication to HTTP based backend. A file containing the PEM encoded private key and certificate can be set using the --tls-client-cert option.

https://github.com/restic/restic/issues/1522 https://github.com/restic/restic/pull/1524
Enhancement #1541: Reduce number of remote requests during repository check

This change eliminates redundant remote repository calls and significantly improves repository check time.

https://github.com/restic/restic/issues/1541 https://github.com/restic/restic/pull/1548
Enhancement #1567: Reduce number of backend requests for rebuild-index and prune

We've found a way to reduce then number of backend requests for the rebuild-index and prune operations. This significantly speeds up the operations for high-latency backends.

https://github.com/restic/restic/issues/1567 https://github.com/restic/restic/pull/1574 https://github.com/restic/restic/pull/1575
Enhancement #1507: Only reload snapshots once per minute for fuse mount

https://github.com/restic/restic/pull/1507
Enhancement #1538: Reduce memory allocations for querying the index

This change reduces the internal memory allocations when the index data structures in memory are queried if a blob (part of a file) already exists in the repo. It should speed up backup a bit, and maybe even reduce RAM usage.

https://github.com/restic/restic/pull/1538
Enhancement #1549: Speed up querying across indices and scanning existing files

This change increases the whenever a blob (part of a file) is searched for in a restic repository. This will reduce cpu usage some when backing up files already backed up by restic. Cpu usage is further decreased when scanning files.

https://github.com/restic/restic/pull/1549
Enhancement #1554: Fuse/mount: Correctly handle EOF, add template option

We've added the --snapshot-template string, which can be used to specify a template for a snapshot directory. In addition, accessing data after the end of a file via the fuse mount is now handled correctly.

https://github.com/restic/restic/pull/1554
Enhancement #1564: Don't terminate ssh on SIGINT

We've reworked the code which runs the ssh login for the sftp backend so that it can prompt for a password (if needed) but does not exit when the user presses CTRL+C (SIGINT) e.g. during backup. This allows restic to properly shut down when it receives SIGINT and remove the lock file from the repo, afterwards exiting the ssh process.

https://github.com/restic/restic/pull/1564 https://github.com/restic/restic/pull/1588
Enhancement #1579: Retry Backend.List() in case of errors

https://github.com/restic/restic/pull/1579
Enhancement #1584: Limit index file size

Before, restic would create a single new index file on prune or rebuild-index, this may lead to memory problems when this huge index is created and loaded again. We're now limiting the size of the index file, and split newly created index files into several smaller ones. This allows restic to be more memory-efficient.

Bugfix #1457: Improve s3 backend with DigitalOcean Spaces

https://github.com/restic/restic/issues/1457 https://github.com/restic/restic/pull/1459
Bugfix #1454: Correct cache dir location for Windows and Darwin

The cache directory on Windows and Darwin was not correct, instead the directory .cache was used.

https://github.com/restic/restic/pull/1454
Bugfix #1459: Disable handling SIGPIPE

We've disabled handling SIGPIPE again. Turns out, writing to broken TCP connections also raised SIGPIPE, so restic exits on the first write to a broken connection. Instead, restic should retry the request.

https://github.com/restic/restic/issues/1457 https://github.com/restic/restic/issues/1466 https://github.com/restic/restic/pull/1459
Change #1452: Do not save atime by default

By default, the access time for files and dirs is not saved any more. It is not possible to reliably disable updating the access time during a backup, so for the next backup the access time is different again. This means a lot of metadata is saved. If you want to save the access time anyway, pass --with-atime to the backup command.

https://github.com/restic/restic/pull/1452
Enhancement #1436: Add code to detect old cache directories

We've added code to detect old cache directories of repositories that haven't been used in a long time, restic now prints a note when it detects that such dirs exist. Also, the option --cleanup-cache was added to automatically remove such directories. That's not a problem because the cache will be rebuild once a repo is accessed again.

https://github.com/restic/restic/pull/1436
Enhancement #1439: Improve cancellation logic

The cancellation logic was improved, restic can now shut down cleanly when requested to do so (e.g. via ctrl+c).

https://github.com/restic/restic/pull/1439
Enhancement #11: Add the diff command

The command diff was added, it allows comparing two snapshots and listing all differences.

Security #1445: Prevent writing outside the target directory during restore

A vulnerability was found in the restic restorer, which allowed attackers in special circumstances to restore files to a location outside of the target directory. Due to the circumstances we estimate this to be a low-risk vulnerability, but urge all users to upgrade to the latest version of restic.

Exploiting the vulnerability requires a Linux/Unix system which saves backups via restic and a Windows systems which restores files from the repo. In addition, the attackers need to be able to create files with arbitrary names which are then saved to the restic repo. For example, by creating a file named "..\test.txt" (which is a perfectly legal filename on Linux) and restoring a snapshot containing this file on Windows, it would be written to the parent of the target directory.

We'd like to thank Tyler Spivey for reporting this responsibly!

https://github.com/restic/restic/pull/1445
Bugfix #1256: Re-enable workaround for S3 backend

We've re-enabled a workaround for minio-go (the library we're using to access s3 backends), this reduces memory usage.

https://github.com/restic/restic/issues/1256 https://github.com/restic/restic/pull/1267
Bugfix #1291: Reuse backend TCP connections to BackBlaze B2

A bug was discovered in the library we're using to access Backblaze, it now reuses already established TCP connections which should be a lot faster and not cause network failures any more.

https://github.com/restic/restic/issues/1291 https://github.com/restic/restic/pull/1301
Bugfix #1317: Run prune when forget --prune is called with just snapshot IDs

A bug in the forget command caused prune not to be run when --prune was specified without a policy, e.g. when only snapshot IDs that should be forgotten are listed manually.

https://github.com/restic/restic/pull/1317
Bugfix #1437: Remove implicit path /restic for the s3 backend

The s3 backend used the subdir restic within a bucket if no explicit path after the bucket name was specified. Since this version, restic does not use this default path any more. If you created a repo on s3 in a bucket without specifying a path within the bucket, you need to add /restic at the end of the repository specification to access your repo: s3:s3.amazonaws.com/bucket/restic

https://github.com/restic/restic/issues/1292 https://github.com/restic/restic/pull/1437
Enhancement #1102: Add subdirectory ids to fuse mount

The fuse mount now has an ids subdirectory which contains the snapshots below their (short) IDs.

https://github.com/restic/restic/issues/1102 https://github.com/restic/restic/pull/1299 https://github.com/restic/restic/pull/1320
Enhancement #1114: Add --cacert to specify TLS certificates to check against

We've added the --cacert option which can be used to pass one (or more) CA certificates to restic. These are used in addition to the system CA certificates to verify HTTPS certificates (e.g. for the REST backend).

https://github.com/restic/restic/issues/1114 https://github.com/restic/restic/pull/1276
Enhancement #1216: Add upload/download limiting

We've added support for rate limiting through --limit-upload and --limit-download flags.

https://github.com/restic/restic/issues/1216 https://github.com/restic/restic/pull/1336 https://github.com/restic/restic/pull/1358
Enhancement #1271: Cache results for excludes for backup

The backup command now caches the result of excludes for a directory.

https://github.com/restic/restic/issues/1271 https://github.com/restic/restic/pull/1326
Enhancement #1274: Add generate command, replaces manpage and autocomplete

The generate command has been added, which replaces the now removed commands manpage and autocomplete. This release of restic contains the most recent manpages in doc/man and the auto-completion files for bash and zsh in doc/bash-completion.sh and doc/zsh-completion.zsh

https://github.com/restic/restic/issues/1274 https://github.com/restic/restic/pull/1282
Enhancement #1367: Allow comments in files read from via --file-from

When the list of files/dirs to be saved is read from a file with --files-from, comment lines (starting with #) are now ignored.

https://github.com/restic/restic/issues/1367 https://github.com/restic/restic/pull/1368
Enhancement #448: Sftp backend prompts for password

The sftp backend now prompts for the password if a password is necessary for login.

https://github.com/restic/restic/issues/448 https://github.com/restic/restic/pull/1270
Enhancement #510: Add dump command

We've added the dump command which prints a file from a snapshot to stdout. This can e.g. be used to restore files read with backup --stdin.

https://github.com/restic/restic/issues/510 https://github.com/restic/restic/pull/1346
Enhancement #1040: Add local metadata cache

We've added a local cache for metadata so that restic doesn't need to load all metadata (snapshots, indexes, ...) from the repo each time it starts. By default the cache is active, but there's a new global option --no-cache that can be used to disable the cache. By deafult, the cache a standard cache folder for the OS, which can be overridden with --cache-dir. The cache will automatically populate, indexes and snapshots are saved as they are loaded. Cache directories for repos that haven't been used recently can automatically be removed by restic with the --cleanup-cache option.

A related change was to by default create pack files in the repo that contain either data or metadata, not both mixed together. This allows easy caching of only the metadata files. The next run of restic prune will untangle mixed files automatically.

Enhancement #1249: Add latest symlink in fuse mount

The directory structure in the fuse mount now exposes a symlink latest which points to the latest snapshot in that particular directory.

https://github.com/restic/restic/pull/1249
Enhancement #1269: Add --compact to forget command

The option --compact was added to the forget command to provide the same compact view as the snapshots command.

https://github.com/restic/restic/pull/1269
Enhancement #1281: Google Cloud Storage backend needs less permissions

The Google Cloud Storage backend no longer requires the service account to have the storage.buckets.get permission ("Storage Admin" role) in restic init if the bucket already exists.

https://github.com/restic/restic/pull/1281
Enhancement #1319: Make check print no errors found explicitly

The check command now explicetly prints No errors were found when no errors could be found.

https://github.com/restic/restic/issues/1303 https://github.com/restic/restic/pull/1319

Bugfix #1167: Do not create a local repo unless init is used

When a restic command other than init is used with a local repository and the repository directory does not exist, restic creates the directory structure. That's an error, only the init command should create the dir.

https://github.com/restic/restic/issues/1167 https://github.com/restic/restic/pull/1182
Bugfix #1164: Make the key remove command behave as documented

https://github.com/restic/restic/pull/1164
Bugfix #1191: Make sure to write profiling files on interrupt

Since a few releases restic had the ability to write profiling files for memory and CPU usage when debug is enabled. It was discovered that when restic is interrupted (ctrl+c is pressed), the proper shutdown hook is not run. This is now corrected.

https://github.com/restic/restic/pull/1191
Enhancement #1132: Make key command always prompt for a password

The key command now prompts for a password even if the original password to access a repo has been specified via the RESTIC_PASSWORD environment variable or a password file.

https://github.com/restic/restic/issues/1132 https://github.com/restic/restic/pull/1133
Enhancement #1179: Resolve name conflicts, append a counter

https://github.com/restic/restic/issues/1179 https://github.com/restic/restic/pull/1209
Enhancement #1218: Add --compact to snapshots command

The option --compact was added to the snapshots command to get a better overview of the snapshots in a repo. It limits each snapshot to a single line.

https://github.com/restic/restic/issues/1218 https://github.com/restic/restic/pull/1223
Enhancement #317: Add --exclude-caches and --exclude-if-present

A new option --exclude-caches was added that allows excluding cache directories (that are tagged as such). This is a special case of a more generic option --exclude-if-present which excludes a directory if a file with a specific name (and contents) is present.

Bugfix #1115: Fix prune, only include existing files in indexes

A bug was found (and corrected) in the index rebuilding after prune, which led to indexes which include blobs that were not present in the repo any more. There were already checks in place which detected this situation and aborted with an error message. A new run of either prune or rebuild-index corrected the index files. This is now fixed and a test has been added to detect this.

https://github.com/restic/restic/pull/1115
Enhancement #1055: Create subdirs below data/ for local/sftp backends

The local and sftp backends now create the subdirs below data/ on open/init. This way, restic makes sure that they always exist. This is connected to an issue for the sftp server.

Enhancement #1067: Allow loading credentials for s3 from IAM

When no S3 credentials are specified in the environment variables, restic now tries to load credentials from an IAM instance profile when the s3 backend is used.

https://github.com/restic/restic/issues/1067 https://github.com/restic/restic/pull/1086
Enhancement #1073: Add migrate cmd to migrate from s3legacy to default layout

The migrate command for changing the s3legacy layout to the default layout for s3 backends has been improved: It can now be restarted with restic migrate --force s3_layout and automatically retries operations on error.

Details

Bugfix #1013: Switch back to using the high-level minio-go API for s3

For the s3 backend we're back to using the high-level API the s3 client library for uploading data, a few users reported dropped connections (which the library will automatically retry now).

https://github.com/restic/restic/issues/1013 https://github.com/restic/restic/issues/1023 https://github.com/restic/restic/pull/1025
Bugfix #965: Switch to default repo layout for the s3 backend

The default layout for the s3 backend is now default (instead of s3legacy). Also, there's a new migrate command to convert an existing repo, it can be run like this: restic migrate s3_layout

https://github.com/restic/restic/issues/965 https://github.com/restic/restic/pull/1004
Enhancement #1021: Detect invalid backend name and print error

Restic now tries to detect when an invalid/unknown backend is used and returns an error message.

https://github.com/restic/restic/issues/1021 https://github.com/restic/restic/pull/1070
Enhancement #1029: Remove invalid pack files when prune is run

The prune command has been improved and will now remove invalid pack files, for example files that have not been uploaded completely because a backup was interrupted.

https://github.com/restic/restic/issues/1029 https://github.com/restic/restic/pull/1036
Enhancement #512: Add Backblaze B2 backend

https://github.com/restic/restic/issues/512 https://github.com/restic/restic/pull/978
Enhancement #636: Add dirs tags and hosts to fuse mount

The fuse mount now has two more directories: tags contains a subdir for each tag, which in turn contains only the snapshots that have this tag. The subdir hosts contains a subdir for each host that has a snapshot, and the subdir contains the snapshots for that host.

https://github.com/restic/restic/issues/636 https://github.com/restic/restic/pull/1050
Enhancement #989: Improve performance of the find command

Improved performance for the find command: Restic recognizes paths it has already checked for the files in question, so the number of backend requests is reduced a lot.

https://github.com/restic/restic/issues/989 https://github.com/restic/restic/pull/993
Enhancement #975: Add new backend for OpenStack Swift

https://github.com/restic/restic/pull/975 https://github.com/restic/restic/pull/648
Enhancement #998: Improve performance of the fuse mount

Listing directories which contain large files now is significantly faster.

Changelog for restic 0.6.1 (2017-06-01)

The following sections list the changes in restic 0.6.1 relevant to restic users. The changes are ordered by importance.

Summary

Enh #985: Allow multiple parallel idle HTTP connections
Enh #981: Remove temporary path from binary in build.go
Enh #974: Remove regular status reports

Details

Enhancement #985: Allow multiple parallel idle HTTP connections

Backends based on HTTP now allow several idle connections in parallel. This is especially important for the REST backend, which (when used with a local server) may create a lot connections and exhaust available ports quickly.

https://github.com/restic/restic/issues/985 https://github.com/restic/restic/pull/986
Enhancement #981: Remove temporary path from binary in build.go

The build.go now strips the temporary directory used for compilation from the binary. This is the first step in enabling reproducible builds.

https://github.com/restic/restic/pull/981
Enhancement #974: Remove regular status reports

Regular status report: We've removed the status report that was printed every 10 seconds when restic is run non-interactively. You can still force reporting the current status by sending a USR1 signal to the process.

Changelog for restic 0.6.0 (2017-05-29)

The following sections list the changes in restic 0.6.0 relevant to restic users. The changes are ordered by importance.

Summary

Enh #957: Make forget consistent
Enh #966: Unify repository layout for all backends
Enh #962: Improve memory and runtime for the s3 backend

Details

Enhancement #957: Make forget consistent

The forget command was corrected to be more consistent in which snapshots are to be forgotten. It is possible that the new code removes more snapshots than before, so please review what would be deleted by using the --dry-run option.

https://github.com/restic/restic/issues/953 https://github.com/restic/restic/pull/957
Enhancement #966: Unify repository layout for all backends

Up to now the s3 backend used a special repository layout. We've decided to unify the repository layout and implemented the default layout also for the s3 backend. For creating a new repository on s3 with the default layout, use restic -o s3.layout=default init. For further commands the option is not necessary any more, restic will automatically detect the correct layout to use. A future version will switch to the default layout for new repositories.

https://github.com/restic/restic/issues/965 https://github.com/restic/restic/pull/966
Enhancement #962: Improve memory and runtime for the s3 backend

We've updated the library used for accessing s3, switched to using a lower level API and added caching for some requests. This lead to a decrease in memory usage and a great speedup. In addition, we added benchmark functions for all backends, so we can track improvements over time. The Continuous Integration test service we're using (Travis) now runs the s3 backend tests not only against a Minio server, but also against the Amazon s3 live service, so we should be notified of any regressions much sooner.
