Tape is -- still -- your friend here. Flip the

the *policies*: what data do you back up, when do you back it up, how
often do you test your backups, and so on. Once you've got that
sorted out, it doesn't really matter whether you're storing the
backups on tape, remote servers, or magic pixie dust.
