We have a separate system for incremental backups. I may decide to discontinue that later, but I prefer to take this one step at a time, and set up a *simple* amanda config at first.

I see the lack of ability to split a directory across several tapes as the one major drawback of Amanda. Also, as long as this functionality isn't there, shouldn't it at least try to rewind and fill the tape with something else when an overflow occurs? > > I'm a little confused, I must admit.

What exactly > are you trying to accomplish? I want to write as much data as possible to each tape. Isn't that obvious? It's not like I have to use all tapes. If I could complete the cycle in less than 5 days, I'd be very happy indeed. - Toralf
