🛠 Bugfix #1212: Restore timestamps and permissions on intermediate directories

⏪ When using the --include option of the restore command, restic restored timestamps and permissions only on directories selected by the include pattern. Intermediate directories, which are necessary to restore files located in sub- directories, were created with default permissions. We've fixed the restore command to restore timestamps and permissions for these directories as well.

#1212 #1402 #2906
🛠 Bugfix #1756: Mark repository files as read-only when using the local backend

🏁 Files stored in a local repository were marked as writeable on the filesystem for non-Windows systems, which did not prevent accidental file modifications outside of restic. In addition, the local backend did not work with certain filesystems and network mounts which do not permit modifications of file permissions.

🏁 Restic now marks files stored in a local repository as read-only on the filesystem on non-Windows systems. The error handling is improved to support more filesystems.

#1756 #2157 #2989
🛠 Bugfix #2241: Hide password in REST backend repository URLs

When using a password in the REST backend repository URL, the password could in some cases be included in the output from restic, e.g. when initializing a repo or during an error.

The password is now replaced with "***" where applicable.

#2241 #2658
🛠 Bugfix #2319: Correctly dump directories into tar files

🏁 The dump command previously wrote directories in a tar file in a way which can cause compatibility problems. This caused, for example, 7zip on Windows to not open tar files containing directories. In addition it was not possible to dump directories with extended attributes. These compatibility problems are now corrected.

In addition, a tar file now includes the name of the owner and group of a file.

#2319 #3039
🛠 Bugfix #2491: Don't require self-update --output placeholder file

⚡️ restic self-update --output /path/to/new-restic used to require that new-restic was an existing file, to be overwritten. Now it's possible to download an updated restic binary to a new path, without first having to create a placeholder file.

#2491 #2937
🛠 Bugfix #2834: Fix rare cases of backup command hanging forever

🛠 We've fixed an issue with the backup progress reporting which could cause restic to hang forever right before finishing a backup.

#2834 #2963
🛠 Bugfix #2938: Fix manpage formatting

🛠 The manpage formatting in restic v0.10.0 was garbled, which is fixed now.

#2938 #2977
🛠 Bugfix #2942: Make --exclude-larger-than handle disappearing files

🛠 There was a small bug in the backup command's --exclude-larger-than option where files that disappeared between scanning and actually backing them up to the repository caused a panic. This is now fixed.

#2942
🛠 Bugfix #2951: Restic generate, help and self-update no longer check passwords

The commands restic cache, generate, help and self-update don't need passwords, but they previously did run the RESTIC_PASSWORD_COMMAND (if set in the environment), prompting users to authenticate for no reason. They now skip running the password command.

#2951 #2987
🛠 Bugfix #2979: Make snapshots --json output [] instead of null when no snapshots

📜 Restic previously output null instead of [] for the --json snapshots command, when there were no snapshots in the repository. This caused some minor problems when parsing the output, but is now fixed such that [] is output when the list of snapshots is empty.

#2979 #2984
✨ Enhancement #2969: Optimize check for unchanged files during backup

During a backup restic skips processing files which have not changed since the last backup run. Previously this required opening each file once which can be slow on network filesystems. The backup command now checks for file changes before opening a file. This considerably reduces the time to create a backup on network filesystems.

#2969 #2970
✨ Enhancement #340: Add support for Volume Shadow Copy Service (VSS) on Windows

⚡️ Volume Shadow Copy Service allows read access to files that are locked by another process using an exclusive lock through a filesystem snapshot. Restic was unable to backup those files before. This update enables backing up these files.

This needs to be enabled explicitely using the --use-fs-snapshot option of the backup command.

#340 #2274
✨ Enhancement #2849: Authenticate to Google Cloud Storage with access token

When using the GCS backend, it is now possible to authenticate with OAuth2 access tokens instead of a credentials file by setting the GOOGLE_ACCESS_TOKEN environment variable.

#2849
✨ Enhancement #1458: New option --repository-file

We've added a new command-line option --repository-file as an alternative to -r. This allows to read the repository URL from a file in order to prevent certain types of information leaks, especially for URLs containing credentials.

#1458 #2900 #2910
✨ Enhancement #2978: Warn if parent snapshot cannot be loaded during backup

During a backup restic uses the parent snapshot to check whether a file was changed and has to be backed up again. For this check the backup has to read the directories contained in the old snapshot. If a tree blob cannot be loaded, restic now warns about this problem with the backup repository.

#2978

Details
🛠 Bugfix #1863: Report correct number of directories processed by backup

🛠 The directory statistics calculation was fixed to report the actual number of processed directories instead of always zero.

#1863
🛠 Bugfix #2254: Fix tar issues when dumping /

🏁 We've fixed an issue with dumping either / or files on the first sublevel e.g. /foo to tar. This also fixes tar dumping issues on Windows where this issue could also happen.

#2254 #2357 #2255
🛠 Bugfix #2281: Handle format verbs like '%' properly in find output

📦 The JSON or "normal" output of the find command can now deal with file names that contain substrings which the Golang fmt package considers "format verbs" like %s.

#2281
🛠 Bugfix #2298: Do not hang when run as a background job

🔧 Restic did hang on exit while restoring the terminal configuration when it was started as a background job, for example using restic ... &. This has been fixed by only restoring the terminal configuration when restic is interrupted while reading a password from the terminal.

#2298
🛠 Bugfix #2389: Fix mangled json output of backup command

🖨 We've fixed a race condition in the json output of the backup command that could cause multiple lines to get mixed up. We've also ensured that the backup summary is printed last.

#2389 #2545
🛠 Bugfix #2390: Refresh lock timestamp

🔒 Long-running operations did not refresh lock timestamp, resulting in locks becoming stale. This is now fixed.

#2390
Bugfix #2429: Backup --json reports total_bytes_processed as 0

We've fixed the json output of total_bytes_processed. The non-json output was already fixed with pull request #2138 but left the json output untouched.

#2429
🛠 Bugfix #2469: Fix incorrect bytes stats in diff command

🛠 In some cases, the wrong number of bytes (e.g. 16777215.998 TiB) were reported by the diff command. This is now fixed.

#2469
🛠 Bugfix #2518: Do not crash with Synology NAS sftp server

🛠 It was found that when restic is used to store data on an sftp server on a Synology NAS with a relative path (one which does not start with a slash), it may go into an endless loop trying to create directories on the server. We've fixed this bug by using a function in the sftp library instead of our own implementation.

🙋 The bug was discovered because the Synology sftp server behaves erratic with non-absolute path (e.g. home/restic-repo). This can be resolved by just using an absolute path instead (/home/restic-repo). We've also added a paragraph in the FAQ.

#2518 #2363 #2530
🛠 Bugfix #2531: Fix incorrect size calculation in stats --mode restore-size

⏪ The restore-size mode of stats was counting hard-linked files as if they were independent.

#2531
🛠 Bugfix #2537: Fix incorrect file counts in stats --mode restore-size

⏪ The restore-size mode of stats was failing to count empty directories and some files with hard links.

#2537
🛠 Bugfix #2592: SFTP backend supports IPv6 addresses

🔧 The SFTP backend now supports IPv6 addresses natively, without relying on aliases in the external SSH configuration.

#2592
Bugfix #2607: Honor RESTIC_CACHE_DIR environment variable on Mac and Windows

On Mac and Windows, the RESTIC_CACHE_DIR environment variable was ignored. This variable can now be used on all platforms to set the directory where restic stores caches.

#2607
🛠 Bugfix #2668: Don't abort the stats command when data blobs are missing

⚙ Runing the stats command in the blobs-per-file mode on a repository with missing data blobs previously resulted in a crash.

#2668
🛠 Bugfix #2674: Add stricter prune error checks

➕ Additional checks were added to the prune command in order to improve resiliency to backend, hardware and/or networking issues. The checks now detect a few more cases where such outside factors could potentially cause data loss.

#2674
🛠 Bugfix #2899: Fix possible crash in the progress bar of check --read-data

🏁 We've fixed a possible crash while displaying the progress bar for the check --read-data command. The crash occurred when the length of the progress bar status exceeded the terminal width, which only happened for very narrow terminal windows.

👯 #2899 https://forum.restic.net/t/restic-rclone-pcloud-connection-issues/2963/15
🔄 Change #2482: Remove vendored dependencies

📚 We've removed the vendored dependencies (in the subdir vendor/). When building restic, the Go compiler automatically fetches the dependencies. It will also cryptographically verify that the correct code has been fetched by using the hashes in go.sum (see the link to the documentation below).

#2482 https://golang.org/cmd/go/#hdr-Module_downloading_and_verification
🔄 Change #2546: Return exit code 3 when failing to backup all source data

The backup command used to return a zero exit code as long as a snapshot could be created successfully, even if some of the source files could not be read (in which case the snapshot would contain the rest of the files).

This made it hard for automation/scripts to detect failures/incomplete backups by looking at the exit code. Restic now returns the following exit codes for the backup command:
- 0 when the command was successful
- 1 when there was a fatal error (no snapshot created)
- 3 when some source data could not be read (incomplete snapshot created)
#956 #2064 #2526 #2364 #2546
⚡️ Change #2600: Update dependencies, require Go >= 1.13

🏗 Restic now requires Go to be at least 1.13. This allows simplifications in the build process and removing workarounds.

🍎 This is also probably the last version of restic still supporting mounting repositories via fuse on macOS. The library we're using for fuse does not support macOS any more and osxfuse is not open source any more.

#224 #590 #2600 #2852 #2927
🔒 Change #1597: Honor the --no-lock flag in the mount command

🔒 The mount command now does not lock the repository if given the --no-lock flag. This allows to mount repositories which are archived on a read only backend/filesystem.

#1597 #2821
✨ Enhancement #1570: Support specifying multiple host flags for various commands

Previously commands didn't take more than one --host or -H argument into account, which could be limiting with e.g. the forget command.

⏪ The dump, find, forget, ls, mount, restore, snapshots, stats and tag commands will now take into account multiple --host and -H flags.

#1570
✨ Enhancement #1680: Optimize restic mount

⚡️ We've optimized the FUSE implementation used within restic. restic mount is now more responsive and uses less memory.

#1680 #2587 #2787
✨ Enhancement #2072: Display snapshot date when using restic find

➕ Added the respective snapshot date to the output of restic find.

#2072
✨ Enhancement #2175: Allow specifying user and host when creating keys

0️⃣ When adding a new key to the repository, the username and hostname for the new key can be specified on the command line. This allows overriding the defaults, for example if you would prefer to use the FQDN to identify the host or if you want to add keys for several different hosts without having to run the key add command on those hosts.

#2175
✨ Enhancement #2277: Add support for ppc64le

➕ Adds support for ppc64le, the processor architecture from IBM.

#2277
✨ Enhancement #2395: Ignore sync errors when operation not supported by local filesystem

🔀 The local backend has been modified to work with filesystems which doesn't support the sync operation. This operation is normally used by restic to ensure that data files are fully written to disk before continuing.

🍎 For these limited filesystems, saving a file in the backend would previously fail with an "operation not supported" error. This error is now ignored, which means that e.g. an SMB mount on macOS can now be used as storage location for a repository.

🔀 #2395 https://forum.restic.net/t/sync-errors-on-mac-over-smb/1859
✨ Enhancement #2427: Add flag --iexclude-file to backup command

👍 The backup command now supports the flag --iexclude-file which is a case-insensitive version of --exclude-file.

#2427 #2898
✨ Enhancement #2569: Support excluding files by their size

👍 The backup command now supports the --exclude-larger-than option to exclude files which are larger than the specified maximum size. This can for example be useful to exclude unimportant files with a large file size.

#2569 #2914
✨ Enhancement #2571: Self-heal missing file parts during backup of unchanged files

We've improved the resilience of restic to certain types of repository corruption.

For files that are unchanged since the parent snapshot, the backup command now verifies that all parts of the files still exist in the repository. Parts that are missing, e.g. from a damaged repository, are backed up again. This verification was already run for files that were modified since the parent snapshot, but is now also done for unchanged files.

Note that restic will not backup file parts that are referenced in the index but where the actual data is not present on disk, as this situation can only be detected by restic check. Please ensure that you run restic check regularly.

#2571 #2827
✨ Enhancement #2858: Support filtering snapshots by tag and path in the stats command

✅ We've added filtering snapshots by --tag tagList and by --path path to the stats command. This includes filtering of only 'latest' snapshots or all snapshots in a repository.

#2858 #2859 https://forum.restic.net/t/stats-for-a-host-and-filtered-snapshots/3020
✨ Enhancement #323: Add command for copying snapshots between repositories

We've added a copy command, allowing you to copy snapshots from one repository to another.

Note that this process will have to read (download) and write (upload) the entire snapshot(s) due to the different encryption keys used on the source and destination repository. Also, the transferred files are not re-chunked, which may break deduplication between files already stored in the destination repo and files copied there using this command.

👍 To fully support deduplication between repositories when the copy command is used, the init command now supports the --copy-chunker-params option, which initializes the new repository with identical parameters for splitting files into chunks as an already existing repository. This allows copied snapshots to be equally deduplicated in both repositories.

#323 #2606 #2928
✨ Enhancement #551: Use optimized library for hash calculation of file chunks

⚡️ We've switched the library used to calculate the hashes of file chunks, which are used for deduplication, to the optimized Minio SHA-256 implementation.

Depending on the CPU it improves the hashing throughput by 10-30%. Modern x86 CPUs with the SHA Extension should be about two to three times faster.

#551 #2709
✨ Enhancement #2195: Simplify and improve restore performance

🐎 Significantly improves restore performance of large files (i.e. 50M+): #2074 https://forum.restic.net/t/restore-using-rclone-gdrive-backend-is-slow/1112/8 https://forum.restic.net/t/degraded-restore-performance-s3-backend/1400

🛠 Fixes "not enough cache capacity" error during restore: #2244

⏪ NOTE: This new implementation does not guarantee order in which blobs are written to the target files and, for example, the last blob of a file can be written to the file before any of the preceeding file blobs. It is therefore possible to have gaps in the data written to the target files if restore fails or interrupted by the user.

🐎 The implementation will try to preallocate space for the restored files on the filesystem to prevent file fragmentation. This ensures good read performance for large files, like for example VM images. If preallocating space is not supported by the filesystem, then this step is silently skipped.

#2195 #2893
✨ Enhancement #2328: Improve speed of check command

We've improved the check command to traverse trees only once independent of whether they are contained in multiple snapshots. The check command is now much faster for repositories with a large number of snapshots.

#2284 #2328
✨ Enhancement #2423: Support user@domain parsing as user

➕ Added the ability for user@domain-like users to be authenticated over SFTP servers.

#2423
✨ Enhancement #2576: Improve the chunking algorithm

⚡️ We've updated the chunker library responsible for splitting files into smaller blocks. It should improve the chunking throughput by 5-15% depending on the CPU.

#2820 #2576 #2845
✨ Enhancement #2598: Improve speed of diff command

🐎 We've improved the performance of the diff command when comparing snapshots with similar content. It should run up to twice as fast as before.

#2598
✨ Enhancement #2599: Slightly reduce memory usage of prune and stats commands

The prune and the stats command kept directory identifiers in memory twice while searching for used blobs.

#2599
✨ Enhancement #2733: S3 backend: Add support for WebIdentityTokenFile

👍 We've added support for EKS IAM roles for service accounts feature to the S3 backend.

#2703 #2733
✨ Enhancement #2773: Optimize handling of new index entries

Restic now uses less memory for backups which add a lot of data, e.g. large initial backups. In addition, we've improved the stability in some edge cases.

#2773
✨ Enhancement #2781: Reduce memory consumption of in-memory index

We've improved how the index is stored in memory. This change can reduce memory usage for large repositories by up to 50% (depending on the operation).

#2781 #2812
✨ Enhancement #2786: Optimize list blobs command

We've changed the implementation of list blobs which should be now a bit faster and consume almost no memory even for large repositories.

#2786
✨ Enhancement #2790: Optimized file access in restic mount

Reading large (> 100GiB) files from restic mountpoints is now faster, and the speedup is greater for larger files.

#2790
✨ Enhancement #2840: Speed-up file deletion in forget, prune and rebuild-index

We've sped up the file deletion for the commands forget, prune and rebuild-index, especially for remote repositories. Deletion was sequential before and is now run in parallel.

#2840

Details
🛠 Bugfix #2063: Allow absolute path for filename when backing up from stdin

When backing up from stdin, handle directory path for --stdin-filename. This can be used to specify the full path for the backed-up file.

#2063
🛠 Bugfix #2174: Save files with invalid timestamps

When restic reads invalid timestamps (year is before 0000 or after 9999) it refused to read and archive the file. We've changed the behavior and will now save modified timestamps with the year set to either 0000 or 9999, the rest of the timestamp stays the same, so the file will be saved (albeit with a bogus timestamp).

#2174 #1173
🛠 Bugfix #2249: Read fresh metadata for unmodified files

📇 Restic took all metadata for files which were detected as unmodified, not taking into account changed metadata (ownership, mode). This is now corrected.

#2249 #2252
🛠 Bugfix #2301: Add upper bound for t in --read-data-subset=n/t

256 is the effective maximum for t, but restic would allow larger values, leading to strange behavior.

#2301 #2304
🛠 Bugfix #2321: Check errors when loading index files

🖨 Restic now checks and handles errors which occur when loading index files, the missing check leads to odd errors (and a stack trace printed to users) later. This was reported in the forum.

#2321 https://forum.restic.net/t/check-rebuild-index-prune/1848/13
✨ Enhancement #2179: Use ctime when checking for file changes

📇 Previously, restic only checked a file's mtime (along with other non-timestamp metadata) to decide if a file has changed. This could cause restic to not notice that a file has changed (and therefore continue to store the old version, as opposed to the modified version) if something edits the file and then resets the timestamp. Restic now also checks the ctime of files, so any modifications to a file should be noticed, and the modified file will be backed up. The ctime check will be disabled if the --ignore-inode flag was given.

If this change causes problems for you, please open an issue, and we can look in to adding a seperate flag to disable just the ctime check.

#2179 #2212
✨ Enhancement #2306: Allow multiple retries for interactive password input

Restic used to quit if the repository password was typed incorrectly once. Restic will now ask the user again for the repository password if typed incorrectly. The user will now get three tries to input the correct password before restic quits.

#2306
✨ Enhancement #2330: Make --group-by accept both singular and plural

One can now use the values host/hosts, path/paths and tag / tags interchangeably in the --group-by argument.

#2330
✨ Enhancement #2350: Add option to configure S3 region

0️⃣ We've added a new option for setting the region when accessing an S3-compatible service. For some providers, it is required to set this to a valid value. You can do that either by setting the environment variable AWS_DEFAULT_REGION or using the option s3.region, e.g. like this: -o s3.region="us-east-1".

#2350
v0.9.5 Changes
April 23, 2019
⚡️ We're very pleased to present you restic 0.9.5! 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 >= 0.9.3, 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 easily reproduce a byte identical version from the source code for that release. Instructions on how to do that in the Developer Documentation.

🛠 Bugfix #2135: Return error when no bytes could be read from stdin

📚 We assume that users reading backup data from stdin want to know when no data could be read, so now restic returns an error when backup --stdin is called but no bytes could be read. Usually, this means that an earlier command in a pipe has failed. The documentation was amended and now recommends setting the pipefail option (set -o pipefail).

#2135 #2139
🛠 Bugfix #2181: Don't cancel timeout after 30 seconds for self-update

#2181
🛠 Bugfix #2203: Fix reading passwords from stdin

Passwords for the init, key add, and key passwd commands can now be read from non-terminal stdin.

#2203
🛠 Bugfix #2224: Don't abort the find command when a tree can't be loaded

🔄 Change the find command so that missing trees don't result in a crash. Instead, the error is logged to the debug log, and the tree ID is displayed along with the snapshot it belongs to. This makes it possible to recover repositories that are missing trees by forgetting the snapshots they are used in.

#2224
✨ Enhancement #1895: Add case insensitive include & exclude options

⏪ The backup and restore commands now have --iexclude and --iinclude flags as case insensitive variants of --exclude and --include.

#1895 #2032
✨ Enhancement #1937: Support streaming JSON output for backup

👍 We've added support for getting machine-readable status output during backup, just pass the flag --json for restic backup and restic will output a stream of JSON objects which contain the current progress.

#1937 #1944
✨ Enhancement #2155: Add Openstack application credential auth for Swift

👍 Since Openstack Queens Identity (auth V3) service supports an application credential auth method. It allows to create a technical account with the limited roles. This commit adds an application credential authentication method for the Swift backend.

#2155
✨ Enhancement #2184: Add --json support to forget command

🚚 The forget command now supports the --json argument, outputting the information about what is (or would-be) kept and removed from the repository.

#2184 #2185
✨ Enhancement #2037: Add group-by option to snapshots command

0️⃣ We have added an option to group the output of the snapshots command, similar to the output of the forget command. The option has been called "--group-by" and accepts any combination of the values "host", "paths" and "tags", separated by commas. Default behavior (not specifying --group-by) has not been changed. We have added support of the grouping to the JSON output.

#2037 #2087
✨ Enhancement #2124: Ability to dump folders to tar via stdout

We've added the ability to dump whole folders to stdout via the dump command. Restic now requires at least Go 1.10 due to a limitation of the standard library for Go <= 1.9.

#2123 #2124
✨ Enhancement #2139: Return error if no bytes could be read for backup --stdin

When restic is used to backup the output of a program, like mysqldump | restic backup --stdin, it now returns an error if no bytes could be read at all. This catches the failure case when mysqldump failed for some reason and did not output any data to stdout.

#2139
✨ Enhancement #2205: Add --ignore-inode option to backup cmd

🛠 This option handles backup of virtual filesystems that do not keep fixed inodes for files, like Fuse-based, pCloud, etc. Ignoring inode changes allows to consider the file as unchanged if last modification date and size are unchanged.

#1631 #2205 #2047
✨ Enhancement #2220: Add config option to set S3 storage class

The s3.storage-class option can be passed to restic (using -o) to specify the storage class to be used for S3 objects created by restic.

The storage class is passed as-is to S3, so it needs to be understood by the API. On AWS, it can be one of STANDARD, STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING and REDUCED_REDUNDANCY. If unspecified, the default storage class is used (STANDARD on AWS).

You can mix storage classes in the same bucket, and the setting isn't stored in the restic repository, so be sure to specify it with each command that writes to S3.

Details
🛠 Bugfix #1989: Google Cloud Storage: Respect bandwidth limit

🔧 The GCS backend did not respect the bandwidth limit configured, a previous commit accidentally removed support for it.

#1989 #2100
🛠 Bugfix #2040: Add host name filter shorthand flag for stats command

✅ The default value for --host flag was set to 'H' (the shorthand version of the flag), this caused the lookup for the latest snapshot to fail.

➕ Add shorthand flag -H for --host (with empty default so if these flags are not specified the latest snapshot will not filter by host name).

Also add shorthand -H for backup command.

#2040
🛠 Bugfix #2068: Correctly return error loading data

In one case during prune and check, an error loading data from the backend is not returned properly. This is now corrected.

#1999 #2068
🛠 Bugfix #2095: Consistently use local time for snapshots times

0️⃣ By default snapshots created with restic backup were set to local time, but when the --time flag was used the provided timestamp was parsed as UTC. With this change all snapshots times are set to local time.

#2095
✨ Enhancement #1605: Concurrent restore

🐎 This change significantly improves restore performance, especially when using high-latency remote repositories like B2.

⏪ The implementation now uses several concurrent threads to download and process multiple remote files concurrently. To further reduce restore time, each remote file is downloaded using a single repository request.

#1605 #1719
✨ Enhancement #2089: Increase granularity of the "keep within" retention policy

✅ The keep-within option of the forget command now accepts time ranges with an hourly granularity. For example, running restic forget --keep-within 3d12h will keep all the snapshots made within three days and twelve hours from the time of the latest snapshot.

#2089 #2090
✨ Enhancement #2097: Add key hinting

Added a new option --key-hint and corresponding environment variable RESTIC_KEY_HINT. The key hint is a key ID to try decrypting first, before other keys in the repository.

This change will benefit repositories with many keys; if the correct key hint is supplied then restic only needs to check one key. If the key hint is incorrect (the key does not exist, or the password is incorrect) then restic will check all keys, as usual.

#2097
✨ Enhancement #2017: Mount: Enforce FUSE Unix permissions with allow-other

0️⃣ The fuse mount (restic mount) now lets the kernel check the permissions of the files within snapshots (this is done through the DefaultPermissions FUSE option) when the option --allow-other is specified.

⏪ To restore the old behavior, we've added the --no-default-permissions option. This allows all users that have access to the mount point to access all files within the snapshots.

#2017
✨ Enhancement #2070: Make all commands display timestamps in local time

🖨 Restic used to drop the timezone information from displayed timestamps, it now converts timestamps to local time before printing them so the times can be easily compared to.

#2070
✨ Enhancement #2085: Allow --files-from to be specified multiple times

Before, restic took only the last file specified with --files-from into account, this is now corrected.

#2085 #2086
✨ Enhancement #2094: Run command to get password

We've added the --password-command option which allows specifying a command that restic runs every time the password for the repository is needed, so it can be integrated with a password manager or keyring. The option can also be set via the environment variable $RESTIC_PASSWORD_COMMAND.

#2094
v0.9.3 Changes

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

0️⃣ 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

🛠 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

0️⃣ 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.

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.

#1834 #1835

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.
0️⃣ 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.

✨ 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.

0️⃣ 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.

✨ 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.

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.

✨ 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.

v0.8.3 Changes
February 26, 2018
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.

🛠 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.
