7.4.2.4 Peculiarities of backing up to tapes
Backup options
You can configure the Tape management (p. 124) backup options to determine:

When to eject a tape.

Whether to use a free tape for each full, incremental or differential backup.

Whether to overwrite a tape when creating a full backup (for stand-alone tape drives only).

Whether to use a separate tape set for backing up each machine.

Whether to enable file recovery from disk-level backups stored on tapes.
Backup schemes
Simple scheme
When you use the Simple backup scheme (p. 64), only full backups can be created on tapes. This is
because backups located on tapes cannot be consolidated (p. 434). If you had the option of creating
incremental backups, you would not be able to delete any of the backups.
Grandfather-Father-Son and Tower of Hanoi schemes
By default, the Grandfather-Father-Son (p. 65) and Tower of Hanoi (p. 71) backup schemes create
only full backups on tapes. This helps the software to delete each backup on time as defined by the
backup scheme.
You may want to change the default setting to creating full, incremental and differential backups. For
example, if you have a few tapes but your full backups are quite large, you may want to save space
on tapes.
Each level of the above schemes uses a separate tape set within the same tape pool. This means that
the software can only take a tape belonging to a certain tape set or a free tape (when space is
running out on the currently used tape). This helps minimize the quantity of used tapes, because
tapes with incremental and differential backups are filled and rewritten more often than tapes with
full backups.
