Release Notes

restic/restic

v0.16.0: restic 0.16.0

Compare Source

restic 0.16.0 has been released!

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. If you already have restic >= 0.9.4, you can use restic self-update to get the latest version in a secure way.

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

Details

  • Bugfix #​2565: Support "unlimited" in forget --keep-* options

    Restic would previously forget snapshots that should have been kept when a negative value was passed to the --keep-* options. Negative values are now forbidden. To keep all snapshots, the special value unlimited is now supported. For example, --keep-monthly unlimited will keep all monthly snapshots.

    #​2565 #​4234

  • Bugfix #​3311: Support non-UTF8 paths as symlink target

    Earlier restic versions did not correctly backup and restore symlinks that contain a non-UTF8 target. Note that this only affected systems that still use a non-Unicode encoding for filesystem paths.

    The repository format is now extended to add support for such symlinks. Please note that snapshots must have been created with at least restic version 0.16.0 for restore to correctly handle non-UTF8 symlink targets when restoring them.

    #​3311 #​3802

  • Bugfix #​4199: Avoid lock refresh issues on slow network connections

    On network connections with a low upload speed, backups and other operations could fail with the error message Fatal: failed to refresh lock in time.

    This has now been fixed by reworking the lock refresh handling.

    #​4199 #​4304

  • Bugfix #​4274: Improve lock refresh handling after standby

    If the restic process was stopped or the host running restic entered standby during a long running operation such as a backup, this previously resulted in the operation failing with Fatal: failed to refresh lock in time.

    This has now been fixed such that restic first checks whether it is safe to continue the current operation and only throws an error if not.

    #​4274 #​4374

  • Bugfix #​4319: Correctly clean up status bar output of the backup command

    Due to a regression in restic 0.15.2, the status bar of the backup command could leave some output behind. This happened if filenames were printed that are wider than the current terminal width. This has now been fixed.

    #​4319 #​4318

  • Bugfix #​4333: generate and init no longer silently ignore unexpected arguments

    #​4333

  • Bugfix #​4400: Ignore missing folders in rest backend

    If a repository accessed via the REST backend was missing folders, then restic would fail with an error while trying to list the data in the repository. This has been now fixed.

    #​235 #​4400

  • Change #​4176: Fix JSON message type of scan_finished for the backup command

    Restic incorrectly set the message_type of the scan_finished message to status instead of verbose_status. This has now been corrected so that the messages report the correct type.

    #​4176

  • Change #​4201: Require Go 1.20 for Solaris builds

    Building restic on Solaris now requires Go 1.20, as the library used to access Azure uses the mmap syscall, which is only available on Solaris starting from Go 1.20. All other platforms however continue to build with Go 1.18.

    #​4201

  • Enhancement #​426: Show progress bar during restore

    The restore command now shows a progress report while restoring files.

    Example: [0:42] 5.76% 23 files 12.98 MiB, total 3456 files 23.54 GiB

    JSON output is now also supported.

    #​426 #​3413 #​3627 #​3991 #​4314 https://forum.restic.net/t/progress-bar-for-restore/5210

  • Enhancement #​719: Add --retry-lock option

    This option allows specifying a duration for which restic will wait if the repository is already locked.

    #​719 #​2214 #​4107

  • Enhancement #​1495: Sort snapshots by timestamp in restic find

    The find command used to print snapshots in an arbitrary order. Restic now prints snapshots sorted by timestamp.

    #​1495 #​4409

  • Enhancement #​1759: Add repair index and repair snapshots commands

    The rebuild-index command has been renamed to repair index. The old name will still work, but is deprecated.

    When a snapshot was damaged, the only option up to now was to completely forget the snapshot, even if only some unimportant files in it were damaged and other files were still fine.

    Restic now has a repair snapshots command, which can salvage any non-damaged files and parts of files in the snapshots by removing damaged directories and missing file contents. Please note that the damaged data may still be lost and see the "Troubleshooting" section in the documentation for more details.

    #​1759 #​1714 #​1798 #​2334 #​2876 https://forum.restic.net/t/corrupted-repo-how-to-repair/799https://forum.restic.net/t/recovery-options-for-damaged-repositories/1571

  • Enhancement #​1926: Allow certificate paths to be passed through environment variables

    Restic will now read paths to certificates from the environment variables RESTIC_CACERT or RESTIC_TLS_CLIENT_CERT if --cacert or --tls-client-cert are not specified.

    #​1926 #​4384

  • Enhancement #​2359: Provide multi-platform Docker images

    The official Docker images are now built for the architectures linux/386, linux/amd64, linux/arm and linux/arm64.

    As an alternative to the Docker Hub, the Docker images are also available on ghcr.io, the GitHub Container Registry.

    #​2359 #​4269 #​4364

  • Enhancement #​2468: Add support for non-global Azure clouds

    The azure backend previously only supported storages using the global domain core.windows.net. This meant that backups to other domains such as Azure China (core.chinacloudapi.cn) or Azure Germany (core.cloudapi.de) were not supported. Restic now allows overriding the global domain using the environment variable AZURE_ENDPOINT_SUFFIX.

    #​2468 #​4387

  • Enhancement #​2679: Reduce file fragmentation for local backend

    Before this change, local backend files could become fragmented. Now restic will try to preallocate space for pack files to avoid their fragmentation.

    #​2679 #​3261

  • Enhancement #​3328: Reduce memory usage by up to 25%

    The in-memory index has been optimized to be more garbage collection friendly. Restic now defaults to GOGC=50 to run the Go garbage collector more frequently.

    #​3328 #​4352 #​4353

  • Enhancement #​3397: Improve accuracy of ETA displayed during backup

    Restic's backup command displayed an ETA that did not adapt when the rate of progress made during the backup changed during the course of the backup.

    Restic now uses recent progress when computing the ETA. It is important to realize that the estimate may still be wrong, because restic cannot predict the future, but the hope is that the ETA will be more accurate in most cases.

    #​3397 #​3563

  • Enhancement #​3624: Keep oldest snapshot when there are not enough snapshots

    The forget command now additionally preserves the oldest snapshot if fewer snapshots than allowed by the --keep-* parameters would otherwise be kept. This maximizes the amount of history kept within the specified limits.

    #​3624 #​4366 https://forum.restic.net/t/keeping-yearly-snapshots-policy-when-backup-began-during-the-year/4670/2

  • Enhancement #​3698: Add support for Managed / Workload Identity to azure backend

    Restic now additionally supports authenticating to Azure using Workload Identity or Managed Identity credentials, which are automatically injected in several environments such as a managed Kubernetes cluster.

    #​3698 #​4029

  • Enhancement #​3871: Support <snapshot>:<subfolder> syntax to select subfolders

    Commands like diff or restore always worked with the full snapshot. This did not allow comparing only a specific subfolder or only restoring that folder (restore --include subfolder filters the restored files, but still creates the directories included in subfolder).

    The commands diff, dump, ls and restore now support the <snapshot>:<subfolder> syntax, where snapshot is the ID of a snapshot (or the string latest) and subfolder is a path within the snapshot. The commands will then only work with the specified path of the snapshot. The subfolder must be a path to a folder as returned by ls. Two examples:

    restic restore -t target latest:/some/path restic diff 12345678:/some/path 90abcef:/some/path

    For debugging purposes, the cat command now supports cat tree <snapshot>:<subfolder> to return the directory metadata for the given subfolder.

    #​3871 #​4334

  • Enhancement #​3941: Support --group-by for backup parent selection

    Previously, the backup command by default selected the parent snapshot based on the hostname and the backup targets. When the backup path list changed, the backup command was unable to determine a suitable parent snapshot and had to read all files again.

    The new --group-by option for the backup command allows filtering snapshots for the parent selection by host, paths and tags. It defaults to host,paths which selects the latest snapshot with hostname and paths matching those of the backup run. This matches the behavior of prior restic versions.

    The new --group-by option should be set to the same value as passed to forget --group-by.

    #​3941 #​4081

  • Enhancement #​4130: Cancel current command if cache becomes unusable

    If the cache directory was removed or ran out of space while restic was running, this would previously cause further caching attempts to fail and thereby drastically slow down the command execution. Now, the currently running command is instead canceled.

    #​4130 #​4166

  • Enhancement #​4159: Add --human-readable option to ls and find commands

    Previously, when using the -l option with the ls and find commands, the displayed size was always in bytes, without an option for a more human readable format such as MiB or GiB.

    The new --human-readable option will convert longer size values into more human friendly values with an appropriate suffix depending on the output size. For example, a size of 14680064 will be shown as 14.000 MiB.

    #​4159 #​4351

  • Enhancement #​4188: Include restic version in snapshot metadata

    The restic version used to backup a snapshot is now included in its metadata and shown when inspecting a snapshot using restic cat snapshot <snapshotID> or restic snapshots --json.

    #​4188 #​4378

  • Enhancement #​4220: Add jq binary to Docker image

    The Docker image now contains jq, which can be useful to process JSON data output by restic.

    #​4220

  • Enhancement #​4226: Allow specifying region of new buckets in the gs backend

    Previously, buckets used by the Google Cloud Storage backend would always get created in the "us" region. It is now possible to specify the region where a bucket should be created by using the -o gs.region=us option.

    #​4226

  • Enhancement #​4375: Add support for extended attributes on symlinks

    Restic now supports extended attributes on symlinks when backing up, restoring, or FUSE-mounting snapshots. This includes, for example, the security.selinux xattr on Linux distributions that use SELinux.

    #​4375 #​4379
