Details
-------
* 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.
https://github.com/restic/restic/pull/1454
* Bugfix #1457: 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 the `backup` command.
https://github.com/restic/restic/pull/1452
* 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.
https://github.com/restic/restic/pull/1436
* 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).
https://github.com/restic/restic/pull/1439
* Enhancement #11: Add the `diff` command
The 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

Details
-------
* 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!
https://github.com/restic/restic/pull/1445
* 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 IDs
A bug in the `forget` command caused `prune` not to be run when `--prune` was specified without a
policy, e.g. when only snapshot IDs that should be forgotten are listed manually.
https://github.com/restic/restic/pull/1317
* Bugfix #1292: Remove implicit path `/restic` for the s3 backend
The 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 mount
The 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 against
We'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, replaces `manpage` and `autocomplete`
The `generate` command has been added, which replaces the now removed commands `manpage` and
`autocomplete`. This release of restic contains the most recent manpages in `doc/man` and the
auto-completion files for bash and zsh in `doc/bash-completion.sh` and
`doc/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` command
We've added the `dump` command which prints a file from a snapshot to stdout. This can e.g. be
used to restore files read with `backup --stdin`.
https://github.com/restic/restic/issues/510
https://github.com/restic/restic/pull/1346
* Enhancement #29: 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/pull/1265
* Enhancement #1249: Add `latest` symlink in fuse mount
The directory structure in the fuse mount now exposes a symlink `latest` which points to the
latest snapshot in that particular directory.
https://github.com/restic/restic/pull/1249
* Enhancement #1269: Add `--compact` to `forget` command
The option `--compact` was added to the `forget` command to provide the same compact view as the
`snapshots` command.
https://github.com/restic/restic/pull/1269
* 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) in `restic init` if the bucket
already exists.
https://github.com/restic/restic/pull/1281
* Enhancement #1303: Make `check` print `no errors found` explicitly
The `check` command now explicetly prints `No errors were found` when no errors could be found.
https://github.com/restic/restic/issues/1303
https://github.com/restic/restic/pull/1319
* Enhancement #1353: Retry failed backend requests

Changelog for restic 0.7.3 (2017-09-20)
=======================================
The following sections list the changes in restic 0.7.3 relevant to
restic users. The changes are ordered by importance.
Summary
-------
* Fix #1246: List all files stored in Google Cloud Storage
Details
-------
* Bugfix #1246: List all files stored in Google Cloud Storage
For large backups stored in Google Cloud Storage, the `prune` command fails because listing
only returns the first 1000 files. This has been corrected, no data is lost in the process. In
addition, a plausibility check was added to `prune`.
https://github.com/restic/restic/issues/1246
https://github.com/restic/restic/pull/1247

Details
-------
* Bugfix #1167: Do not create a local repo unless `init` is used
When 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 the
`init` 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
https://github.com/restic/restic/pull/1164
* 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.
https://github.com/restic/restic/pull/1191
* Enhancement #1132: Make `key` command always prompt for a password
The `key` command now prompts for a password even if the original password to access a repo has
been specified via the `RESTIC_PASSWORD` environment variable or a password file.
https://github.com/restic/restic/issues/1132
https://github.com/restic/restic/pull/1133
* Enhancement #1179: Resolve name conflicts, append a counter
https://github.com/restic/restic/issues/1179
https://github.com/restic/restic/pull/1209
* Enhancement #1218: Add `--compact` to `snapshots` command
The option `--compact` was added to the `snapshots` 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 #697: Automatically generate man pages for all restic commands
https://github.com/restic/restic/issues/697
https://github.com/restic/restic/pull/1147
* Enhancement #1044: Improve `restore`, do not traverse/load excluded directories
https://github.com/restic/restic/pull/1044
* Enhancement #1061: Add Dockerfile and official Docker image
https://github.com/restic/restic/pull/1061
* Enhancement #1126: Use the standard Go git repository layout, use `dep` for vendoring
The 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 by `dep`.
https://github.com/restic/restic/pull/1126
* Enhancement #211: Add support for storing backups on Google Cloud Storage
https://github.com/restic/restic/issues/211
https://github.com/restic/restic/pull/1134
https://github.com/restic/restic/pull/1052
* Enhancement #1144: Properly report errors when reading files with exclude patterns.
https://github.com/restic/restic/pull/1144
* Enhancement #609: 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.
https://github.com/restic/restic/issues/609
https://github.com/restic/restic/pull/1149
https://github.com/restic/restic/pull/1059

Changelog for restic 0.7.1 (2017-07-22)
=======================================
The following sections list the changes in restic 0.7.1 relevant to
restic users. The changes are ordered by importance.
Summary
-------
* Fix #1115: Fix `prune`, only include existing files in indexes
* Enh #1055: Create subdirs below `data/` for local/sftp backends
* Enh #1067: Allow loading credentials for s3 from IAM
* Enh #1073: Add `migrate` cmd to migrate from `s3legacy` to `default` layout
* Enh #1081: Clarify semantic for `--tasg` for the `forget` command
* Enh #1080: Ignore chmod() errors on filesystems which do not support it
* Enh #1082: Print stats on SIGINFO on Darwin and FreeBSD (ctrl+t)
Details
-------
* Bugfix #1115: Fix `prune`, only include existing files in indexes
A 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` or
`rebuild-index` corrected the index files. This is now fixed and a test has been added to detect
this.
https://github.com/restic/restic/pull/1115
* Enhancement #1055: Create subdirs below `data/` for local/sftp backends
The local and sftp backends now create the subdirs below `data/` on open/init. This way, restic
makes sure that they always exist. This is connected to an issue for the sftp server:
https://github.com/restic/restic/issues/1055
https://github.com/restic/restic/pull/1077
https://github.com/restic/restic/pull/1105
https://github.com/restic/rest-server/pull/11#issuecomment-309879710
* 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.
https://github.com/restic/restic/issues/1067
https://github.com/restic/restic/pull/1086
* Enhancement #1073: Add `migrate` cmd to migrate from `s3legacy` to `default` layout
The `migrate` command for chaning the `s3legacy` layout to the `default` layout for s3
backends has been improved: It can now be restarted with `restic migrate --force s3_layout`
and automatically retries operations on error.
https://github.com/restic/restic/issues/1073
https://github.com/restic/restic/pull/1075

restic users. The changes are ordered by importance.
Summary
-------
* Fix #1013: Switch back to using the high-level minio-go API for s3
* Fix #965: Switch to `default` repo layout for the s3 backend
* Enh #1021: Detect invalid backend name and print error
* Enh #1029: Remove invalid pack files when `prune` is run
* Enh #512: Add Backblaze B2 backend
* Enh #636: Add dirs `tags` and `hosts` to fuse mount
* Enh #989: Improve performance of the `find` command
* Enh #975: Add new backend for OpenStack Swift
* Enh #998: Improve performance of the fuse mount
Details
-------
* 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).
https://github.com/restic/restic/issues/1013
https://github.com/restic/restic/issues/1023
https://github.com/restic/restic/pull/1025
* Bugfix #965: Switch to `default` repo layout for the s3 backend
The default layout for the s3 backend is now `default` (instead of `s3legacy`). Also, there's a
new `migrate` 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 run
The `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` and `hosts` to fuse mount
The 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 subdir `hosts` 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` command
Improved 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.
https://github.com/restic/restic/pull/998
Changelog for restic 0.6.1 (2017-06-01)
=======================================
The following sections list the changes in restic 0.6.1 relevant to
restic users. The changes are ordered by importance.
Summary
-------
* Enh #985: Allow multiple parallel idle HTTP connections
* Enh #981: Remove temporary path from binary in `build.go`
* Enh #974: Remove regular status reports
Details
-------
* Enhancement #985: Allow multiple parallel idle HTTP connections
Backends based on HTTP now allow several idle connections in parallel. This is especially
important for the REST backend, which (when used with a local server) may create a lot
connections and exhaust available ports quickly.
https://github.com/restic/restic/issues/985
https://github.com/restic/restic/pull/986
* Enhancement #981: Remove temporary path from binary in `build.go`
The `build.go` now strips the temporary directory used for compilation from the binary. This
is the first step in enabling reproducible builds.
https://github.com/restic/restic/pull/981
* Enhancement #974: Remove regular status reports
Regular status report: We've removed the status report that was printed every 10 seconds when
restic is run non-interactively. You can still force reporting the current status by sending a
`USR1` signal to the process.
https://github.com/restic/restic/pull/974
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 #953: Make `forget` consistent
* Enh #965: Unify repository layout for all backends
* Enh #962: Improve memory and runtime for the s3 backend
Details
-------
* Enhancement #953: Make `forget` consistent
The `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 #965: 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.

* 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.
