tresor is an application for performing full
backup and fast restores with bytepositioning tape
drives. This option is available on some Tandberg
and Wangtek streamers and some SCSI-2 tape drives.
It features flexible configuration, a database for
multiple volumes, fast restores (due to direct
seeking), a graphical user interface, tape
operations based on dd, afio, and mt, and tape
identification using its own header. Language
support for German and English is included.
