 ===========
 
 For a repository using at least repository format version 2, you can configure how 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
-slightly 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``.
