This file describes changes relevant to all users that are made in each
released version of restic from the perspective of the user.
Important Changes in 0.X.Y
==========================
* 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.
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
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
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.
