i can't refute the arguement there. yes, it's "just a matter of turning
around and changing tapes" for some installations.

most home users don't need something as heavy duty as amanda, since
they're more likely to have a single machine they need backed up.. no,
you, and i, are not "most home users". the average home users machine
still has the ability of storing more data than can be backed up easily
(assuming a level 0 backup for the first tape..) by any tape device.

when you're talking about 200gigs of mp3s, though, you're really going to
need to look at another backup system for just those mp3s. something not
on tape, just highly reliable. some folk have discussed in the past of
using hard drives (either mirrored, or in a RAID). check the archives for
some details on what people here on -chat do.

once the server is configured, clients just kind of fall in to place. the
article on amanda at backup central[0] (a chapter from O'Reilly's Unix
Backup and Recovery[1]) is *very* helpful in the setup. very clear, very
simple, and good. Another good resource is an article from SAMags Backup
Issue, which is also available online[2]. i happen to like amanda,
overall.
