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. + + https://github.com/restic/restic/issues/2565 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/3311 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/4199 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/4274 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/4319 + https://github.com/restic/restic/pull/4318 + + * Bugfix #4333: `generate` and `init` no longer silently ignore unexpected arguments + + https://github.com/restic/restic/pull/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. + + https://github.com/restic/rest-server/issues/235 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/426 + https://github.com/restic/restic/issues/3413 + https://github.com/restic/restic/issues/3627 + https://github.com/restic/restic/pull/3991 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/719 + https://github.com/restic/restic/pull/2214 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/1495 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/1759 + https://github.com/restic/restic/issues/1714 + https://github.com/restic/restic/issues/1798 + https://github.com/restic/restic/issues/2334 + https://github.com/restic/restic/pull/2876 + https://forum.restic.net/t/corrupted-repo-how-to-repair/799 + https://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. + + https://github.com/restic/restic/issues/1926 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/2359 + https://github.com/restic/restic/issues/4269 + https://github.com/restic/restic/pull/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`. + + https://github.com/restic/restic/issues/2468 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/2679 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/3328 + https://github.com/restic/restic/pull/4352 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/3397 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/3624 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/3698 + https://github.com/restic/restic/pull/4029 + + * Enhancement #3871: Support `:` 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 `:` + 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 :` to + return the directory metadata for the given subfolder. + + https://github.com/restic/restic/issues/3871 + https://github.com/restic/restic/pull/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`. + + https://github.com/restic/restic/issues/3941 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/4130 + https://github.com/restic/restic/pull/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`. + + https://github.com/restic/restic/issues/4159 + https://github.com/restic/restic/pull/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 ` or `restic snapshots + --json`. + + https://github.com/restic/restic/issues/4188 + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/pull/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. + + https://github.com/restic/restic/issues/4375 + https://github.com/restic/restic/pull/4379 + + Changelog for restic 0.15.2 (2023-04-24) =======================================
