I'm currently working on amanda's support. It's not what I would call
the most graceful solution and it's not built in - you have to graft a
bunch of pieces on to make it work.

Teradactyl worries the hell out of me. They're a small company with
about 12 customers from what I can tell AND their closed source. So if
they go away so does my ability to deal with my backups. Not a good
combination. At least with TSM you had only to worry about IBM changing
their mind on you - but not outright vanishing as a result of a few bad

So the features I want in a backup system is:
 - open source
 - capable of dealing with afs (acls included) in a way that doesn't
make me feel like I'm using bailing wire and duct tape to backup my
mission-critical data.
