I don't think anyone else has mentioned backuppc4afs. We've been
running it for a bit now in parallel to our older system and it
seems to work reasonably well.
It is disk-based, no tape support at all. You could use a standard
tape backup program to back up backuppc4afs's backup store.
You may see mention elsewhere that using tape to backup a backuppc data
store is untenable; this is true due to non-afs backuppc's extensive
use of hard links as a poor-man's dedup.
backuppc4afs does not do the hardlink bit, since it does individual vos
dumps and the expectation is that no two vos dumps will ever be identical.
