Bugfix: Downgrade zstd library to fix rare data corruption at max. compression
|
||
|
|
|
||
|
|
In restic 0.16.3, backups where the compression level was set to `max` (using
|
||
|
|
`--compression max`) could in rare and very specific circumstances result in
|
||
|
|
data corruption due to a bug in the library used for compressing data. Restic
|
||
|
|
0.16.1 and 0.16.2 were not affected.
|
||
|
|
|
||
|
|
Restic now uses the previous version of the library used to compress data, the
|
||
|
|
same version used by restic 0.16.2. Please note that the `auto` compression
|
||
|
|
level (which restic uses by default) was never affected, and even if you used
|
||
|
|
`max` compression, chances of being affected by this issue are small.
|
||
|
|
|
||
|
|
To check a repository for any corruption, run `restic check --read-data`. This
|
||
|
|
will download and verify the whole repository and can be used at any time to
|
||
|
|
completely verify the integrity of a repository. If the `check` command detects
|
||
|
|
anomalies, follow the suggested steps.
