Details

• 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

• 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
• Enh #1436: Add code to detect old cache directories
• Enh #1439: Improve cancellation logic
• Enh #11: Add the diff command

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

• 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

  https://github.com/restic/restic/pull/1353

Summary

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

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.

  https://github.com/restic/restic/issues/1246 https://github.com/restic/restic/pull/1247

• 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

• Enhancement #697: Automatically generate man pages for all restic commands

  https://github.com/restic/restic/issues/697 https://github.com/restic/restic/pull/1147

• Enhancement #1044: Improve restore, do not traverse/load excluded directories

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

• 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 chaning 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.

  https://github.com/restic/restic/issues/1073 https://github.com/restic/restic/pull/1075

• Enhancement #1081: Clarify semantic for --tasg for the forget command

• 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.
