I've used it for years. If you have indexing on, the restore
process isn't horrible but still not very intuitive. Since finding
backuppc I only use amanda for tapes to be kept offsite and
hope I don't ever need to do a restore from them.

Amanda typically does many filesystems from many machines in a
backup run. It can't split any individual filesystem across
tapes, but can spread the run over different tapes. What it
does better than anything else I've seen is automatically
manage the mix of full and incremental runs each night to
fill the tape and be sure you have at least one full of
each filesystem in a predefined tape set and at least an
incremental of every filesystem every night. It actually
gets an estimate of sizes from each machine before starting
and will bump the incremental levels if needed to make

Yes, bacula looks like it might do everything in one program
but you really can't beat backuppc for ease of use and
the amount of data it can store in a given amount of space.
It doesn't use tapes (well, you can archive the last backup
off to tape but it's an afterthought), but now that disk
space it cheap it is something to consider. If offsite
storage isn't necessary or can be arranged by periodically
doing an image copy of the backuppc disk archive, I wouldn't
bother with tapes these days.
