So to clarify just so that I understand correctly: 1. Each filesystem per system to be backed up qualifies as a dumpfile. 2. Multiple dumpfiles per backup 3. Multiple tapes per backup, as long as 1 dumpfile isn't larger than the tape.
One of my systems has a 120 gig drive with about 36gigs (and growing) of people's images, documents, etc on it (samba server). My single tape drive is only 20 gigs. I am assuming this will be a problem for Amanda unless I get a bigger tape drive.
