Bugfix #1633: Fixed unexpected 'pack file cannot be listed' error
Due to a regression introduced in 0.8.2, the
rebuild-index
andprune
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
-
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 whenrestic 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.
-
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.
-
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.
-
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.

Bugfix #1506: Limit bandwith at the http.RoundTripper for HTTP based backends
https://github.com/restic/restic/issues/1506 https://github.com/restic/restic/pull/1511
-
Bugfix #1512: Restore directory permissions as the last step
This change allows restoring into directories that were not writable during backup. Before, restic created the directory, set the read-only mode and then failed to create files in the directory. This change now restores the directory (with its permissions) as the very last step.
https://github.com/restic/restic/issues/1512 https://github.com/restic/restic/pull/1536
-
Bugfix #1528: Correctly create missing subdirs in data/
https://github.com/restic/restic/issues/1528 https://github.com/restic/restic/pull/1529
-
Bugfix #1590: Strip spaces for lines read via --files-from
Leading and trailing spaces in lines read via
--files-from
are now stripped, so it behaves the same as with lines read via--exclude-file
.https://github.com/restic/restic/issues/1590 https://github.com/restic/restic/pull/1613
-
Bugfix #1589: Complete intermediate index upload
After a user posted a comprehensive report of what he observed, we were able to find a bug and correct it: During backup, restic uploads so-called "intermediate" index files. When the backup finishes during a transfer of such an intermediate index, the upload is cancelled, but the backup is finished without an error. This leads to an inconsistent state, where the snapshot references data that is contained in the repo, but is not referenced in any index.
The situation can be resolved by building a new index with
rebuild-index
, but looks very confusing at first. Since all the data got uploaded to the repo successfully, there was no risk of data loss, just minor inconvenience for our users. -
Bugfix #1594: Google Cloud Storage: Use generic HTTP transport
It was discovered that the Google Cloud Storage backend did not use the generic HTTP transport, so things such as bandwidth limiting with
--limit-upload
did not work. This is resolved now. -
Bugfix #1595: Backup: Remove bandwidth display
This commit removes the bandwidth displayed during backup process. It is misleading and seldomly correct, because it's neither the "read bandwidth" (only for the very first backup) nor the "upload bandwidth". Many users are confused about (and rightly so), c.f. #1581, #1033, #1591
We'll eventually replace this display with something more relevant when the new archiver code is ready.
-
Enhancement #1522: Add support for TLS client certificate authentication
Support has been added for using a TLS client certificate for authentication to HTTP based backend. A file containing the PEM encoded private key and certificate can be set using the
--tls-client-cert
option.https://github.com/restic/restic/issues/1522 https://github.com/restic/restic/pull/1524
-
Enhancement #1541: Reduce number of remote requests during repository check
This change eliminates redundant remote repository calls and significantly improves repository check time.
https://github.com/restic/restic/issues/1541 https://github.com/restic/restic/pull/1548
-
Enhancement #1567: Reduce number of backend requests for rebuild-index and prune
We've found a way to reduce then number of backend requests for the
rebuild-index
andprune
operations. This significantly speeds up the operations for high-latency backends.https://github.com/restic/restic/issues/1567 https://github.com/restic/restic/pull/1574 https://github.com/restic/restic/pull/1575
-
Enhancement #1507: Only reload snapshots once per minute for fuse mount
-
Enhancement #1538: Reduce memory allocations for querying the index
This change reduces the internal memory allocations when the index data structures in memory are queried if a blob (part of a file) already exists in the repo. It should speed up backup a bit, and maybe even reduce RAM usage.
-
Enhancement #1549: Speed up querying across indices and scanning existing files
This change increases the whenever a blob (part of a file) is searched for in a restic repository. This will reduce cpu usage some when backing up files already backed up by restic. Cpu usage is further decreased when scanning files.
-
Enhancement #1554: Fuse/mount: Correctly handle EOF, add template option
We've added the
--snapshot-template
string, which can be used to specify a template for a snapshot directory. In addition, accessing data after the end of a file via the fuse mount is now handled correctly. -
Enhancement #1564: Don't terminate ssh on SIGINT
We've reworked the code which runs the
ssh
login for the sftp backend so that it can prompt for a password (if needed) but does not exit when the user presses CTRL+C (SIGINT) e.g. during backup. This allows restic to properly shut down when it receives SIGINT and remove the lock file from the repo, afterwards exiting thessh
process.https://github.com/restic/restic/pull/1564 https://github.com/restic/restic/pull/1588
-
Enhancement #1579: Retry Backend.List() in case of errors
-
Enhancement #1584: Limit index file size
Before, restic would create a single new index file on
prune
orrebuild-index
, this may lead to memory problems when this huge index is created and loaded again. We're now limiting the size of the index file, and split newly created index files into several smaller ones. This allows restic to be more memory-efficient.https://github.com/restic/restic/issues/1412 https://github.com/restic/restic/issues/979 https://github.com/restic/restic/issues/526 https://github.com/restic/restic/pull/1584

Bugfix #1457: Improve s3 backend with DigitalOcean Spaces
https://github.com/restic/restic/issues/1457 https://github.com/restic/restic/pull/1459
-
Bugfix #1454: Correct cache dir location for Windows and Darwin
The cache directory on Windows and Darwin was not correct, instead the directory
.cache
was used. -
Bugfix #1459: Disable handling SIGPIPE
We've disabled handling SIGPIPE again. Turns out, writing to broken TCP connections also raised SIGPIPE, so restic exits on the first write to a broken connection. Instead, restic should retry the request.
https://github.com/restic/restic/issues/1457 https://github.com/restic/restic/issues/1466 https://github.com/restic/restic/pull/1459
-
Change #1452: Do not save atime by default
By default, the access time for files and dirs is not saved any more. It is not possible to reliably disable updating the access time during a backup, so for the next backup the access time is different again. This means a lot of metadata is saved. If you want to save the access time anyway, pass
--with-atime
to thebackup
command. -
Enhancement #1436: Add code to detect old cache directories
We've added code to detect old cache directories of repositories that haven't been used in a long time, restic now prints a note when it detects that such dirs exist. Also, the option
--cleanup-cache
was added to automatically remove such directories. That's not a problem because the cache will be rebuild once a repo is accessed again. -
Enhancement #1439: Improve cancellation logic
The cancellation logic was improved, restic can now shut down cleanly when requested to do so (e.g. via ctrl+c).
-
Enhancement #11: Add the
diff
commandThe command
diff
was added, it allows comparing two snapshots and listing all differences.https://github.com/restic/restic/issues/11 https://github.com/restic/restic/issues/1460 https://github.com/restic/restic/pull/1462

Security #1445: Prevent writing outside the target directory during restore
A vulnerability was found in the restic restorer, which allowed attackers in special circumstances to restore files to a location outside of the target directory. Due to the circumstances we estimate this to be a low-risk vulnerability, but urge all users to upgrade to the latest version of restic.
Exploiting the vulnerability requires a Linux/Unix system which saves backups via restic and a Windows systems which restores files from the repo. In addition, the attackers need to be able to create create files with arbitrary names which are then saved to the restic repo. For example, by creating a file named "..\test.txt" (which is a perfectly legal filename on Linux) and restoring a snapshot containing this file on Windows, it would be written to the parent of the target directory.
We'd like to thank Tyler Spivey for reporting this responsibly!
-
Bugfix #1256: Re-enable workaround for S3 backend
We've re-enabled a workaround for
minio-go
(the library we're using to access s3 backends), this reduces memory usage.https://github.com/restic/restic/issues/1256 https://github.com/restic/restic/pull/1267
-
Bugfix #1291: Reuse backend TCP connections to BackBlaze B2
A bug was discovered in the library we're using to access Backblaze, it now reuses already established TCP connections which should be a lot faster and not cause network failures any more.
https://github.com/restic/restic/issues/1291 https://github.com/restic/restic/pull/1301
-
Bugfix #1317: Run prune when
forget --prune
is called with just snapshot IDsA bug in the
forget
command causedprune
not to be run when--prune
was specified without a policy, e.g. when only snapshot IDs that should be forgotten are listed manually. -
Bugfix #1437: Remove implicit path
/restic
for the s3 backendThe s3 backend used the subdir
restic
within a bucket if no explicit path after the bucket name was specified. Since this version, restic does not use this default path any more. If you created a repo on s3 in a bucket without specifying a path within the bucket, you need to add/restic
at the end of the repository specification to access your repo:s3:s3.amazonaws.com/bucket/restic
https://github.com/restic/restic/issues/1292 https://github.com/restic/restic/pull/1437
-
Enhancement #1102: Add subdirectory
ids
to fuse mountThe fuse mount now has an
ids
subdirectory which contains the snapshots below their (short) IDs.https://github.com/restic/restic/issues/1102 https://github.com/restic/restic/pull/1299 https://github.com/restic/restic/pull/1320
-
Enhancement #1114: Add
--cacert
to specify TLS certificates to check againstWe've added the
--cacert
option which can be used to pass one (or more) CA certificates to restic. These are used in addition to the system CA certificates to verify HTTPS certificates (e.g. for the REST backend).https://github.com/restic/restic/issues/1114 https://github.com/restic/restic/pull/1276
-
Enhancement #1216: Add upload/download limiting
We've added support for rate limiting through
--limit-upload
and--limit-download
flags.https://github.com/restic/restic/issues/1216 https://github.com/restic/restic/pull/1336 https://github.com/restic/restic/pull/1358
-
Enhancement #1271: Cache results for excludes for
backup
The
backup
command now caches the result of excludes for a directory.https://github.com/restic/restic/issues/1271 https://github.com/restic/restic/pull/1326
-
Enhancement #1274: Add
generate
command, replacesmanpage
andautocomplete
The
generate
command has been added, which replaces the now removed commandsmanpage
andautocomplete
. This release of restic contains the most recent manpages indoc/man
and the auto-completion files for bash and zsh indoc/bash-completion.sh
anddoc/zsh-completion.zsh
https://github.com/restic/restic/issues/1274 https://github.com/restic/restic/pull/1282
-
Enhancement #1367: Allow comments in files read from via
--file-from
When the list of files/dirs to be saved is read from a file with
--files-from
, comment lines (starting with#
) are now ignored.https://github.com/restic/restic/issues/1367 https://github.com/restic/restic/pull/1368
-
Enhancement #448: Sftp backend prompts for password
The sftp backend now prompts for the password if a password is necessary for login.
https://github.com/restic/restic/issues/448 https://github.com/restic/restic/pull/1270
-
Enhancement #510: Add
dump
commandWe've added the
dump
command which prints a file from a snapshot to stdout. This can e.g. be used to restore files read withbackup --stdin
.https://github.com/restic/restic/issues/510 https://github.com/restic/restic/pull/1346
-
Enhancement #1040: Add local metadata cache
We've added a local cache for metadata so that restic doesn't need to load all metadata (snapshots, indexes, ...) from the repo each time it starts. By default the cache is active, but there's a new global option
--no-cache
that can be used to disable the cache. By deafult, the cache a standard cache folder for the OS, which can be overridden with--cache-dir
. The cache will automatically populate, indexes and snapshots are saved as they are loaded. Cache directories for repos that haven't been used recently can automatically be removed by restic with the--cleanup-cache
option.A related change was to by default create pack files in the repo that contain either data or metadata, not both mixed together. This allows easy caching of only the metadata files. The next run of
restic prune
will untangle mixed files automatically.https://github.com/restic/restic/issues/29 https://github.com/restic/restic/issues/738 https://github.com/restic/restic/issues/282 https://github.com/restic/restic/pull/1040 https://github.com/restic/restic/pull/1287 https://github.com/restic/restic/pull/1436 https://github.com/restic/restic/pull/1265
-
Enhancement #1249: Add
latest
symlink in fuse mountThe directory structure in the fuse mount now exposes a symlink
latest
which points to the latest snapshot in that particular directory. -
Enhancement #1269: Add
--compact
toforget
commandThe option
--compact
was added to theforget
command to provide the same compact view as thesnapshots
command. -
Enhancement #1281: Google Cloud Storage backend needs less permissions
The Google Cloud Storage backend no longer requires the service account to have the
storage.buckets.get
permission ("Storage Admin" role) inrestic init
if the bucket already exists. -
Enhancement #1319: Make
check
printno errors found
explicitlyThe
check
command now explicetly printsNo errors were found
when no errors could be found.https://github.com/restic/restic/issues/1303 https://github.com/restic/restic/pull/1319

Bugfix #1167: Do not create a local repo unless
init
is usedWhen a restic command other than
init
is used with a local repository and the repository directory does not exist, restic creates the directory structure. That's an error, only theinit
command should create the dir.https://github.com/restic/restic/issues/1167 https://github.com/restic/restic/pull/1182
-
Bugfix #1164: Make the
key remove
command behave as documented -
Bugfix #1191: Make sure to write profiling files on interrupt
Since a few releases restic had the ability to write profiling files for memory and CPU usage when
debug
is enabled. It was discovered that when restic is interrupted (ctrl+c is pressed), the proper shutdown hook is not run. This is now corrected. -
Enhancement #1132: Make
key
command always prompt for a passwordThe
key
command now prompts for a password even if the original password to access a repo has been specified via theRESTIC_PASSWORD
environment variable or a password file.https://github.com/restic/restic/issues/1132 https://github.com/restic/restic/pull/1133

-
Enhancement #1218: Add
--compact
tosnapshots
commandThe option
--compact
was added to thesnapshots
command to get a better overview of the snapshots in a repo. It limits each snapshot to a single line.https://github.com/restic/restic/issues/1218 https://github.com/restic/restic/pull/1223
-
Enhancement #317: Add
--exclude-caches
and--exclude-if-present
A new option
--exclude-caches
was added that allows excluding cache directories (that are tagged as such). This is a special case of a more generic option--exclude-if-present
which excludes a directory if a file with a specific name (and contents) is present.https://github.com/restic/restic/issues/317 https://github.com/restic/restic/pull/1170 https://github.com/restic/restic/pull/1224

Enhancement #1061: Add Dockerfile and official Docker image
-
Enhancement #1126: Use the standard Go git repository layout, use
dep
for vendoringThe git repository layout was changed to resemble the layout typically used in Go projects, we're not using
gb
for building restic any more and vendoring the dependencies is now taken care of bydep
. -

Enhancement #1144: Properly report errors when reading files with exclude patterns
-
Enhancement #1149: Add support for storing backups on Microsoft Azure Blob Storage
The library we're using to access the service requires Go 1.8, so restic now needs at least Go 1.8.

Details
-
Bugfix #1115: Fix
prune
, only include existing files in indexesA bug was found (and corrected) in the index rebuilding after prune, which led to indexes which include blobs that were not present in the repo any more. There were already checks in place which detected this situation and aborted with an error message. A new run of either
prune
orrebuild-index
corrected the index files. This is now fixed and a test has been added to detect this. -
Enhancement #1055: Create subdirs below
data/
for local/sftp backendsThe local and sftp backends now create the subdirs below

Enhancement #1067: Allow loading credentials for s3 from IAM
When no S3 credentials are specified in the environment variables, restic now tries to load credentials from an IAM instance profile when the s3 backend is used.

Bugfix #1013: Switch back to using the high-level minio-go API for s3
For the s3 backend we're back to using the high-level API the s3 client library for uploading data, a few users reported dropped connections (which the library will automatically retry now).

-
Bugfix #965: Switch to
default
repo layout for the s3 backendThe default layout for the s3 backend is now
default
(instead ofs3legacy
). Also, there's a newmigrate
command to convert an existing repo, it can be run like this:restic migrate s3_layout
https://github.com/restic/restic/issues/965 https://github.com/restic/restic/pull/1004
-
Enhancement #1021: Detect invalid backend name and print error
Restic now tries to detect when an invalid/unknown backend is used and returns an error message.
https://github.com/restic/restic/issues/1021 https://github.com/restic/restic/pull/1070
-
Enhancement #1029: Remove invalid pack files when
prune
is runThe
prune
command has been improved and will now remove invalid pack files, for example files that have not been uploaded completely because a backup was interrupted.https://github.com/restic/restic/issues/1029 https://github.com/restic/restic/pull/1036
-
Enhancement #512: Add Backblaze B2 backend
https://github.com/restic/restic/issues/512 https://github.com/restic/restic/pull/978
-
Enhancement #636: Add dirs
tags
andhosts
to fuse mountThe fuse mount now has two more directories:
tags
contains a subdir for each tag, which in turn contains only the snapshots that have this tag. The subdirhosts
contains a subdir for each host that has a snapshot, and the subdir contains the snapshots for that host.https://github.com/restic/restic/issues/636 https://github.com/restic/restic/pull/1050
-
Enhancement #989: Improve performance of the
find
commandImproved performance for the
find
command: Restic recognizes paths it has already checked for the files in question, so the number of backend requests is reduced a lot.https://github.com/restic/restic/issues/989 https://github.com/restic/restic/pull/993
-
Enhancement #975: Add new backend for OpenStack Swift
https://github.com/restic/restic/pull/975 https://github.com/restic/restic/pull/648
-
Enhancement #998: Improve performance of the fuse mount
Listing directories which contain large files now is significantly faster.

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

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. -
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.
Changelog for restic 0.6.0 (2017-05-29)
The following sections list the changes in restic 0.6.0 relevant to restic users. The changes are ordered by importance.
Summary
- Enh #957: Make
forget
consistent - Enh #966: Unify repository layout for all backends
- Enh #962: Improve memory and runtime for the s3 backend
Details
-
Enhancement #957: Make
forget
consistentThe
forget
command was corrected to be more consistent in which snapshots are to be forgotten. It is possible that the new code removes more snapshots than before, so please review what would be deleted by using the--dry-run
option.https://github.com/restic/restic/issues/953 https://github.com/restic/restic/pull/957
-
Enhancement #966: Unify repository layout for all backends
Up to now the s3 backend used a special repository layout. We've decided to unify the repository layout and implemented the default layout also for the s3 backend. For creating a new repository on s3 with the default layout, use
restic -o s3.layout=default init
. For further commands the option is not necessary any more, restic will automatically detect the correct layout to use. A future version will switch to the default layout for new repositories.https://github.com/restic/restic/issues/965 https://github.com/restic/restic/pull/966
-
Enhancement #962: Improve memory and runtime for the s3 backend
We've updated the library used for accessing s3, switched to using a lower level API and added caching for some requests. This lead to a decrease in memory usage and a great speedup. In addition, we added benchmark functions for all backends, so we can track improvements over time. The Continuous Integration test service we're using (Travis) now runs the s3 backend tests not only against a Minio server, but also against the Amazon s3 live service, so we should be notified of any regressions much sooner.
