Backup and restore using tape drive proceed in the same way as with other devices, with
the following exceptions.
1. A full backup can be stored on an empty tape only. If the tape already contains data,
its contents will be overwritten on prompt. You have an option to disable prompts. See
details in
5.3.11 Additional settings .
2. In case you want to keep more than one archive on the tape, for example, back up two
disks separately, choose
incremental backup mode instead of a full backup when you
create an initial backup for the second disk. In other situations, incremental backup is
used for appending changes to the previously created archive.
3. You do not have to provide filenames for backups.
You might experience short pauses that are required to rewind the tape.
Low-quality or old tape, as well as dirt on the magnetic head, might lead to pauses that
can last up to several minutes.
