[CentOS] Backup Redux

So going back to Amanda and Bacula ... I seem to recall that Amanda uses
standard tools on the back end like gtar and/or dump, is that right?

What does Bacula use?  Does it use one of the standard tools?  Or does it
have its own proprietary format that it uses?

thanks,
-Alan
