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  It used to be possible to specify multiple snapshots, but that has been replaced by only one snapshot and the possibility of specifying multiple directories.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

Changelog for restic 0.9.2 (2018-08-06)

The following sections list the changes in restic 0.9.2 relevant to restic users. The changes are ordered by importance.

Summary

• Fix #1854: Allow saving files/dirs on different fs with --one-file-system
• Fix #1870: Fix restore with --include
• Fix #1880: Use --cache-dir argument for check command
• Fix #1893: Return error when exclude file cannot be read
• Fix #1861: Fix case-insensitive search with restic find
• Enh #1906: Add support for B2 application keys
• Enh #874: Add stats command to get information about a repository
• Enh #1772: Add restore --verify to verify restored file content
• Enh #1853: Add JSON output support to restic key list
• Enh #1477: S3 backend: accept AWS_SESSION_TOKEN
• Enh #1901: Update the Backblaze B2 library

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.

  https://github.com/restic/restic/issues/1834 https://github.com/restic/restic/pull/1835

Changelog for restic 0.9.0 (2018-05-21)

• Enh #1735: Allow keeping a time range of snaphots
• Enh #1782: Use default AWS credentials chain for S3 backend

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.

  https://github.com/restic/restic/issues/549 https://github.com/restic/restic/issues/1286 https://github.com/restic/restic/issues/446 https://github.com/restic/restic/issues/1344 https://github.com/restic/restic/issues/1416 https://github.com/restic/restic/issues/1456 https://github.com/restic/restic/issues/1145 https://github.com/restic/restic/issues/1160 https://github.com/restic/restic/pull/1494

• 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.

  https://github.com/restic/restic/pull/1552 https://developers.google.com/identity/protocols/application-default-credentials

• 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.

  https://github.com/restic/restic/pull/1648

• 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.

  https://github.com/restic/restic/pull/1709 https://forum.restic.net/t/what-is-the-standard-procedure-to-follow-if-a-backup-or-restore-is-interrupted/571/2

• Enhancement #827: Add --new-password-file flag for non-interactive password changes

  This makes it possible to change a repository password without being prompted.

  https://github.com/restic/restic/issues/827 https://github.com/restic/restic/pull/1720 https://forum.restic.net/t/changing-repo-password-without-prompt/591

• 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.

  https://github.com/restic/restic/pull/1782

Changelog for restic 0.8.3 (2018-02-26)

The following sections list the changes in restic 0.8.3 relevant to restic users. The changes are ordered by importance.

Summary

• Fix #1633: Fixed unexpected 'pack file cannot be listed' error
• Fix #1641: Ignore files with invalid names in the repo
• Fix #1638: Handle errors listing files in the backend
• Enh #1497: Add --read-data-subset flag to check command
• Enh #1560: Retry all repository file download errors
• Enh #1623: Don't check for presence of files in the backend before writing
• Enh #1634: Upgrade B2 client library, reduce HTTP requests

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.

• 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.

  https://github.com/restic/restic/issues/1412 https://github.com/restic/restic/issues/979 https://github.com/restic/restic/issues/526 https://github.com/restic/restic/pull/1584

Changelog for restic 0.8.1 (2017-12-27)

The following sections list the changes in restic 0.8.1 relevant to restic users. The changes are ordered by importance.

Summary

• Fix #1457: Improve s3 backend with DigitalOcean Spaces
• Fix #1454: Correct cache dir location for Windows and Darwin
• Fix #1459: Disable handling SIGPIPE
• Chg #1452: Do not save atime by default

Details

• 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.

  https://github.com/restic/restic/issues/11 https://github.com/restic/restic/issues/1460 https://github.com/restic/restic/pull/1462

Changelog for restic 0.8.0 (2017-11-26)

The following sections list the changes in restic 0.8.0 relevant to restic users. The changes are ordered by importance.

• Enh #1353: Retry failed backend requests

Details

• 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 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.

  https://github.com/restic/restic/issues/29 https://github.com/restic/restic/issues/738 https://github.com/restic/restic/issues/282 https://github.com/restic/restic/pull/1040 https://github.com/restic/restic/pull/1287 https://github.com/restic/restic/pull/1436 https://github.com/restic/restic/pull/1265

• 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

• Enhancement #1353: Retry failed backend requests

Details

• Bugfix #1246: List all files stored in Google Cloud Storage

  For large backups stored in Google Cloud Storage, the prune command fails because listing only returns the first 1000 files. This has been corrected, no data is lost in the process. In addition, a plausibility check was added to prune.

• Enh #1205: Allow specifying time/date for a backup with --time

Details

• 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.

  https://github.com/restic/restic/issues/317 https://github.com/restic/restic/pull/1170 https://github.com/restic/restic/pull/1224

  https://github.com/restic/restic/pull/1044

• Enhancement #1061: Add Dockerfile and official Docker image

  https://github.com/restic/restic/pull/1061

• Enhancement #1126: Use the standard Go git repository layout, use dep for vendoring

  The git repository layout was changed to resemble the layout typically used in Go projects, we're not using gb for building restic any more and vendoring the dependencies is now taken care of by dep.

  https://github.com/restic/restic/pull/1126

• Enhancement #1134: Add support for storing backups on Google Cloud Storage

  https://github.com/restic/restic/issues/211 https://github.com/restic/restic/pull/1134 https://github.com/restic/restic/pull/1052

• Enhancement #1144: Properly report errors when reading files with exclude patterns

  https://github.com/restic/restic/pull/1144

• Enhancement #1149: Add support for storing backups on Microsoft Azure Blob Storage

  The library we're using to access the service requires Go 1.8, so restic now needs at least Go 1.8.

  https://github.com/restic/restic/issues/609 https://github.com/restic/restic/pull/1149 https://github.com/restic/restic/pull/1059

Changelog for restic 0.7.1 (2017-07-22)

The following sections list the changes in restic 0.7.1 relevant to restic users. The changes are ordered by importance.

Summary

• Fix #1115: Fix prune, only include existing files in indexes
• Enh #1055: Create subdirs below data/ for local/sftp backends
• Enh #1067: Allow loading credentials for s3 from IAM
• Enh #1073: Add migrate cmd to migrate from s3legacy to default layout
• Enh #1081: Clarify semantic for --tasg for the forget command
• Enh #1080: Ignore chmod() errors on filesystems which do not support it
• Enh #1082: Print stats on SIGINFO on Darwin and FreeBSD (ctrl+t)

Details

• 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.

  https://github.com/restic/restic/issues/1055 https://github.com/restic/rest-server/pull/11#issuecomment-309879710 https://github.com/restic/restic/pull/1077 https://github.com/restic/restic/pull/1105

• 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).

• 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

• 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.

• 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.

• 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.

• 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.

• 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.
