I think that that's a darned good question. Skylar's pair of
points misses a key definition. As a guy from Keane that I used to
work with said, no one cares about backups, they only care about
restores.
From the customer's perspective -- which for me is the only
perspective that really counts -- restoration *is* the service; backup
is just the tool that facilitates it.
I've only had to do about one restoration per year over the eight
years I've been at $WORK (small engineering-heavy company).
Bacula (+ LTO) has never failed me during that time. I won't claim
that it's any better than the other tools mention in the OP's list; my
point is that I've found Bacula to be reliable. (I do agree with the
person who lamented Bacula's oft-confusing interface and
documentation.)
If Bacula's catalog is hosted on traditional hard disks, it can take
several minutes to build the dump-like interface to the filesystem to
be restored. I still spool to HDs, but I've moved MySQL to SSDs, and
it's much much much speedier now.
I've deployed rdiff-backup at home, and on a much smaller scale, but
I've never done anything but test restores with it.
