      Create a backup of a system with one extra temporary mounted disk (e.g. /dev/sda with the scsi_debug kernel module) and store it on /dev/vdb. /dev/sda will be missing in the rescue and ReaR will attempt to replace it with /dev/vdb containing the backup. Therefore, the user may lose their backup if they proceed with this suggestion. ReaR should automatically skip all devices with backups when looking for candidates for recreation of missing devices:
