Important Changes in 0.X.Y
|
|
==========================
|
|
|
|
|
|
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
|
|
|
|
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.

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.
|

|
|
|
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:

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.

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
|
|
https://github.com/restic/restic/pull/1070
|
|
|
|
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.
|
|
https://github.com/restic/restic/pull/981
|
|
|
|
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
|
|
only against a Minio server, but also against the Amazon s3 live service, so we
|
|
should be notified of any regressions much sooner.
