Unlike other backup tools such as tar, the commands used by this module bypass the normal filesystem and so cannot be used to backup filesystems of unsupported types, such as NFS or FAT. Generally only the native disk-based filesystem of the operating system that you are running will be supported.
The main page of the module contains a list of configured backups (if any), a button for adding a new backup and a button for restoring a backup of some filesystem type.
