I see no problem with what you describe. I would recommend, only,
performing
more than one backup, or duplicating your tape(s) after the backup, so that
you have more than one copy of your files, possibly stored in different
locations.

It would seem to me that the principle advantage of using Bacula for
your
backup would be that you had a history of your backup(s) in the database for
future reference. If you purge the database, why go to all the bother of
setting up Bacula and, instead, just use tar or cpio to create your backup
tapes.
