We've added compression support to the restic repository format. To create a

You can configure whether data is compressed with the option `--compression`. It
can be set to `auto` (the default, which will compress very fast), `max` (which
will trade backup speed and CPU usage for better compression), or `off` (which
disables compression). Each setting is only applied for the single run of restic.
The option can also be set via the environment variable `RESTIC_COMPRESSION`.
The new format version has not received much testing yet. Do not rely on it as
your only backup copy! Please run `check` in regular intervals to detect any
problems.
To upgrade in place run `migrate upgrade_repo_v2` followed by `prune`. See the
documentation for more details. The migration checks the repository integrity
and upgrades the repository format but will not change any data. Afterwards,
