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.

    #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").

    #1978 #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.

    #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).

    #1909 #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    It used to be possible to specify multiple snapshots, but that has been replaced by only one snapshot and the possibility of specifying multiple directories.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.

    #1940 #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.

    #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.

    #2028 #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.

    #1777 #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!

    #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.

    #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

    #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.

    #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.

    #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.

    #1854 #1855

  • Bugfix #1870: Fix restore with --include

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

    #1870 #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.

    #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.

    #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.

    #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.

    #1906 #1914

  • Enhancement #874: Add stats command to get information about a repository

    #874 #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

    #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.

    #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.

    #1477 #1479 #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.

    #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.

    #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.

    #1825 #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.

    #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.

  • 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.

    #1608 #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.

    #1652 #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.

    #1730 #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.

    #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.

    #1745 #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.

    #1433 #1738 #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.

    #1561 #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.

    #1665 #1694 #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

    #1721 #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.

    #1758 #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.

    #549 #1286 #446 #1344 #1416 #1456 #1145 #1160 #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.

    #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.

    #1477 #1479 #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.

    #1648

  • Enhancement #1649: Add illumos/Solaris support

    #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.

    #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.

    #827 #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.

    #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.

We're very pleased to announce restic 0.8.3! restic is distributed as a standalone binary: download the correct file for your operating system and architecture, extract the file and just run it. If you run into any issues, please report them at the GitHub issue tracker or visit the forum.

The binaries released with each restic version are reproducible, which means that you can easily reproduce a byte identical version from the source code for that release. Instructions on how to do that are contained in the builder repository.

For the 0.8.3 release, the binaries are a bit harder to reproduce since Go 1.10 changed a command-line parameter we're using, and we did not catch this early enough for the release. Instructions on how to reproduce them can be found in the forum.

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.

    #1633 #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.

    #1641 #1643

  • 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.

    #1638

  • 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.

    #1497 #1556

  • Enhancement #1560: Retry all repository file download errors

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

    #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.

    #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.

Details

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

    #1506 #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.

    #1512 #1536

  • Bugfix #1528: Correctly create missing subdirs in data/

    #1528 #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.

    #1590 #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.

    #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.

    #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.

    #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.

    #1522 #1524

  • Enhancement #1541: Reduce number of remote requests during repository check

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

    #1541 #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.

    #1567 #1574 #1575

  • Enhancement #1507: Only reload snapshots once per minute for fuse mount

    #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.

    #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.

    #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.

    #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.

    #1564 #1588

  • Enhancement #1579: Retry Backend.List() in case of errors

    #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.

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

    #1457 #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.

    #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.

    #1457 #1466 #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.

    #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.

    #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).

    #1439

  • Enhancement #11: Add the diff command

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

We're very pleased to announce restic 0.8.0! restic is distributed as a standalone binary: download the correct file for your operating system and architecture, extract the file and just run it. If you run into any issues, please report them at the GitHub issue tracker or visit the forum.

The binaries released with each restic version are reproducible, which means that you can easily reproduce a byte identical version from the source code for that release. Instructions on how to do that are contained in the builder repository.

Important Changes in 0.8.0

  • 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 system 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!
    #1445

  • 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 #1292 #1437

  • 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. #1040 #29 #738 #282 #1287

  • 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. #1265

  • 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. #1281

  • Added support for rate limiting through --limit-upload and --limit-download flags. #1216 #1336 #1358

  • Failed backend requests are now automatically retried. #1353

  • 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. #510 #1346

Small changes

  • The directory structure in the fuse mount now exposes a symlink latest which points to the latest snapshot in that particular directory. #1249

  • The option --compact was added to the forget command to provide the same compact view as the snapshots command. #1269

  • We've re-enabled a workaround for minio-go (the library we're using to access s3 backends), this reduces memory usage. #1256 #1267

  • The sftp backend now prompts for the password if a password is necessary for login. #448 #1270

  • 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 #1274 #1282

  • 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. #1291 #1301

  • Another 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. This is corrected now. #1317

  • The check command now explicetly prints No errors were found when no errors could be found. #1319 #1303

  • The fuse mount now has an ids subdirectory which contains the snapshots below their (short) IDs. #1102 #1299 #1320

  • The backup command was improved, it now caches the result of excludes for a directory. #1271 #1326

  • 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). #1114 #1276

  • When the list of files/dirs to be saved is read from a file with --files-from, comment lines (starting with #) are now ignored. #1367 #1368

Important Changes in 0.7.3

  • 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.

The binaries released with each restic version are reproducible, which means that you can easily reproduce a byte identical version from the source code for that release. Instructions on how to do that are contained in the builder repository.

This release contains the following changes:

Important Changes in 0.7.2

  • We've added an official docker image and a Dockerfile to build this image in
    docker/.
    #1061

  • 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.
    #1126

  • We now support saving backups on Google Cloud Storage.
    #1134
    #1052
    #211

  • We've added support for Microsoft Azure Blob Storage as a restic backend.
    #1149
    #1059
    #609

  • In the course of supporting Microsoft Azure Blobe Storage Go 1.8 is now a
    requirement to build restic.

  • The restore command has been improved: When dirs are excluded (or not
    included) in a restore, they are not loaded from the repo any more.
    #1044

  • Name collisions are now resolved by appending a counter.
    #1179
    #1209

Small changes

  • 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.
    #1132
    #1133

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

  • We now automatically generate man pages for all restic commands, see the
    subdir doc/man.
    #697
    #1147

  • The key remove command was corrected and now works as documented.
    #1164

  • 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.
    #1167
    #1182

  • Restic now prints stats on all BSD systems (not only on darwin) when SIGINFO
    is received (usually when ctrl+t is pressed).
    #1203
    #1082 (comment)

  • 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.
    #1191

  • 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.
    #317
    #1170
    #1224

  • The forget command now has an option --group-by that allows flexible
    grouping policies.
    #1196

  • The date and time restic records for a new backup can now be specified
    externally by passing --time to the backup command.
    #1205

  • 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.
    #1218
    #1223
