You can use one tape in one pool only. In that pool it is possible to
create multiple volumes for both full and diff backups. I think a volume
is something like a file on a tape. And you can have for sure multiple
files on a tape.

If a restore is necessary you bacula will read the full-backup volume
(file) first and then forwind the tape to the diff volume it needs.

Just try it out ;-)

Hope it helps,
Damian
