34.2.3. Unsupported Backup Methods

With unsupported backup methods, there are two options:

The rescue system prompts the user to manually restore the files. This scenario is the one described in "Basic ReaR Usage", except for the backup file format, which may take a different form than a tar archive.
ReaR executes the custom commands provided by the user. To configure this, set the BACKUP directive to EXTERNAL. Then specify the commands to be run during backing up and restoration using the EXTERNAL_BACKUP and EXTERNAL_RESTORE directives. Optionally, also specify the EXTERNAL_IGNORE_ERRORS and EXTERNAL_CHECK directives. See /usr/share/rear/conf/default.conf for an example configuration.
