Details

  • Bugfix #1935: Remove truncated files from cache

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

    https://github.com/restic/restic/issues/1935

  • Bugfix #1978: Do not return an error when the scanner is slower than backup

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

    https://github.com/restic/restic/issues/1978 https://github.com/restic/restic/pull/1991

  • Enhancement #1766: Restore: suppress lchown errors when not running as root

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

    https://github.com/restic/restic/issues/1766

  • Enhancement #1909: Reject files/dirs by name first

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

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

    https://github.com/restic/restic/issues/1909 https://github.com/restic/restic/pull/1912

  • Enhancement #1940: Add directory filter to ls command

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

    It used to be possible to specify multiple snapshots, but that has been replaced by only one snapshot and the possibility of specifying multiple directories.

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

    https://github.com/restic/restic/issues/1940 https://github.com/restic/restic/pull/1941

  • Enhancement #1967: Use --host everywhere

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

    https://github.com/restic/restic/issues/1967

  • Enhancement #2028: Display size of cache directories

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

    https://github.com/restic/restic/issues/2028 https://github.com/restic/restic/pull/2033

  • Enhancement #1777: Improve the find command

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

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

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

    https://github.com/restic/restic/issues/1777 https://github.com/restic/restic/pull/1780

  • Enhancement #1876: Display reason why forget keeps snapshots

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

    https://github.com/restic/restic/pull/1876

  • Enhancement #1891: Accept glob in paths loaded via --files-from

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

    https://github.com/restic/restic/issues/1891

  • Enhancement #1920: Vendor dependencies with Go 1.11 Modules

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

    https://github.com/restic/restic/pull/1920

  • Enhancement #1949: Add new command self-update

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

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

    https://github.com/restic/restic/pull/1949

  • Enhancement #1953: Ls: Add JSON output support for restic ls cmd

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

    https://github.com/restic/restic/pull/1953

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 0.8.3 (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.

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

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.
