I didn't speak up sooner 'cos I don't think it does client/server stuff
but I've been using mondoarchive (http://www.mondorescue.org) as my backup
system. I'm well pleased with it, I've even gone so far as to nuke a
perfectly good system so as to test its restore capabilities. Then I did
it again, this time _without_ the mirror disk on standby!
It _is_ capable of doing multi-box backup but not as a single process.
Instead, you nfs mount the server's fs on the client, run mondoarchive on
the client and then run mondoarchive on the server to get everything onto
Mondo also archives to CDR(W) for those of us not graced/burdened with
tapes. It produces bootable archives with "nuke" and "interactive" modes,
has cloning capabilities for both identical and differing machines.
It's a proper *NIX tool:- uses existing dedicated tools for the various
tasks and, best of all, is all GPL.
 have you ever tried to get a system back _off_ a tape?
