Important Changes in 0.X.Y
|
|
==========================
|
|
|
|
|
|
Small changes
|
|
-------------
|
|
|
|
* 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
|
|
|
|
Important Changes in 0.8.0
|
|
==========================
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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.

https://github.com/restic/restic/pull/1287
|
|
https://github.com/restic/restic/pull/1436
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* Added support for rate limiting through `--limit-upload` and
|
|
`--limit-download` flags.

|
|
|
|
* Failed backend requests are now automatically retried.
|
|
https://github.com/restic/restic/pull/1353
|
|
|
|
* 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`.

|
|
Small changes
|
|
-------------
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* Another 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. This is corrected now.
|
|
https://github.com/restic/restic/pull/1317
|
|
|
|
* The `check` command now explicetly prints `No errors were found` when no
|
|
errors could be found.
|
|
https://github.com/restic/restic/pull/1319
|
|
https://github.com/restic/restic/issues/1303
|
|
|
|
* 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
|
|
|
|
* The `backup` command was improved, it now caches the result of excludes for
|
|
a directory.
|
|
https://github.com/restic/restic/issues/1271
|
|
https://github.com/restic/restic/pull/1326
|
|
|
|
* 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
|
|
|
|
* When the list of files/dirs to be saved is read from a file with
|
|
`--files-from`, comment lines (starting with `#`) are now ignored.
|
|

|
|
|
|
Important Changes in 0.7.3
|
|
==========================
|
|
|
|
* 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
|
|
|
|
|
|
Important Changes in 0.7.2
|
|
==========================
|
|
|
|
* We've added an official docker image and a Dockerfile to build this image in
|
|
`docker/`.
|
|
https://github.com/restic/restic/pull/1061
|
|
|
|
* 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
|
|
|
|
* We now support saving backups on Google Cloud Storage.
|
|
https://github.com/restic/restic/pull/1134
|
|
https://github.com/restic/restic/pull/1052
|
|
https://github.com/restic/restic/issues/211
|
|
|
|
* We've added support for Microsoft Azure Blob Storage as a restic backend.
|
|
https://github.com/restic/restic/pull/1149
|
|
https://github.com/restic/restic/pull/1059
|
|
https://github.com/restic/restic/issues/609
|
|
|
|
* In the course of supporting Microsoft Azure Blobe Storage Go 1.8 is now a
|
|
requirement to build restic.
|
|
|
|
* The `restore` command has been improved: When dirs are excluded (or not
|
|
included) in a restore, they are not loaded from the repo any more.
|
|
https://github.com/restic/restic/pull/1044
|
|
|
|
* Name collisions are now resolved by appending a counter.
|
|
https://github.com/restic/restic/issues/1179
|
|
https://github.com/restic/restic/pull/1209
|
|
|
|
|
|
Small changes
|
|
-------------
|
|
|
|
* 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
|
|
|
|
* Properly report errors when reading files with exclude patterns.
|
|
https://github.com/restic/restic/pull/1144
|
|
|
|
* We now automatically generate man pages for all restic commands, see the
|
|
subdir `doc/man`.
|
|
https://github.com/restic/restic/issues/697
|
|
https://github.com/restic/restic/pull/1147
|
|
|
|
* The `key remove` command was corrected and now works as documented.
|
|
https://github.com/restic/restic/pull/1164
|
|
|
|
* 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
|
|
|
|
* Restic now prints stats on all BSD systems (not only on darwin) when SIGINFO
|
|
is received (usually when ctrl+t is pressed).
|
|
https://github.com/restic/restic/pull/1203
|
|
https://github.com/restic/restic/pull/1082#issuecomment-326279920
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* The `forget` command now has an option `--group-by` that allows flexible
|
|
grouping policies.
|
|
https://github.com/restic/restic/pull/1196
|
|
|
|
* The date and time restic records for a new backup can now be specified
|
|
externally by passing `--time` to the `backup` command.
|
|
https://github.com/restic/restic/pull/1205
|
|
|
|
* 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

|
|
Important Changes in 0.7.1
|
|
==========================
|
|
|
|
* 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
|
|
|
|
Small changes
|
|
-------------
|
|
|
|
* 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/rest-server/pull/11#issuecomment-309879710
|
|
https://github.com/restic/restic/issues/1055
|
|
https://github.com/restic/restic/pull/1077
|
|
https://github.com/restic/restic/pull/1105
|
|
|
|
* 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
|
|
|
|
* On Darwin and FreeBSD, restic now prints stats when SIGINFO is received
|
|
(usually when ctrl+t is pressed).
|
|
https://github.com/restic/restic/pull/1082
|
|
|
|
* The dependencies have been updated.
|
|
https://github.com/restic/restic/pull/1108
|
|
https://github.com/restic/restic/pull/1124
|
|
|
|
* 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
|
|
|
|
* Errors for chmod() on Unix for filesystems which do not support it (e.g. smb
|
|
mounted via gvfs) are now ignored.
|
|
https://github.com/restic/restic/pull/1080
|
|
https://github.com/restic/restic/pull/1112
|
|
|
|
* The semantic for the `--tags` option to `forget` and `snapshots` was
|
|
clarified:

|
https://github.com/restic/restic/issues/1081
|
|
https://github.com/restic/restic/pull/1090

|
|
Important Changes in 0.7.0
|
|
==========================
|
|
|
|
* New "swift" backend: A new backend for the OpenStack Swift cloud storage
|
|
protocol has been added, https://wiki.openstack.org/wiki/Swift
|
|
https://github.com/restic/restic/pull/975
|
|
https://github.com/restic/restic/pull/648
|
|
|
|
* New "b2" backend: A new backend for Backblaze B2 cloud storage
|
|
service has been added, https://www.backblaze.com
|
|
https://github.com/restic/restic/issues/512
|
|
https://github.com/restic/restic/pull/978
|
|
|
|
* 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
|
|
|
|
* Improved performance for the fuse mount: Listing directories which contain
|
|
large files now is significantly faster.
|
|
https://github.com/restic/restic/pull/998
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
Small changes
|
|
-------------
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* restic now tries to detect when an invalid/unknown backend is used and
|
|
returns an error message.
|
|
https://github.com/restic/restic/issues/1021
|

|
Important Changes in 0.6.1
|
|
==========================
|
|
|
|
This is mostly a bugfix release and only contains small changes:
|
|
|
|
* We've fixed a bug where `rebuild-index` would corrupt the index when used
|
|
with the s3 backend together with the `default` layout. This is not the
|
|
default setting.
|
|
|
|
* 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
|
|
|
|
* 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
|
|
|
|
* The `build.go` now strips the temporary directory used for compilation from
|
|
the binary. This is the first step in enabling reproducible builds.
|

Important Changes in 0.6.0
|
|
==========================
|
|
|
|
Consistent forget policy
|
|
------------------------
|
|
|
|
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/pull/957
|
|
https://github.com/restic/restic/issues/953
|
|
|
|
Unified repository layout
|
|
-------------------------
|
|
|
|
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/pull/966
|
|
https://github.com/restic/restic/issues/965
|
|
|
|
Memory and time improvements 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
