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

|
|
|
|
* 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/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
|
|
|
|
* 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.

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.

-------------
|
|
|
|
* 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/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.

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.
|

|
|
|
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.
|

|
|
|
|
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.
