to a drive especially for this operation. If the Use a separate tape set option is enabled, only
incremental and differential backups of the same data will be appended to the tape.

Tape rotation
If all backups are deleted from a tape, i.e. if information about the last backup on the tape is deleted
from the storage node database, the tape is considered as empty and can be reused during a backup
cycle. The same tape rotation enables you to get by with the minimum number of cartridges and not
to be buried in used tapes.

Choosing a backup scheme
When creating a backup policy/plan with a tape library destination, the following backup schemes are
available: Back up now, Back up later, Grandfather-Father-Son, Tower of Hanoi, or Custom. The
Simple backup scheme is disabled, because backup consolidation is impossible for archives located
on tapes.

Tower of Hanoi, and Custom backup schemes.
Grandfather-Father-Son (p. 32) (GFS) and Tower of Hanoi (p. 36) (ToH) are the most popular backup
schemes to use on tape library devices. These schemes are optimized to maintain the best balance
between a backup archive size, the number of recovery points available from the archive, and the
quantity of required tapes for archiving.
