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
BACKUPdirective toEXTERNAL. Then specify the commands to be run during backing up and restoration using theEXTERNAL_BACKUPandEXTERNAL_RESTOREdirectives. Optionally, also specify theEXTERNAL_IGNORE_ERRORSandEXTERNAL_CHECKdirectives. See/usr/share/rear/conf/default.conffor an example configuration.
