And if you are really, really paranoid, you might also want to
consider the possibility of a bug in backuppc, your host OS, or
disk media that will make your primary copy flawed and propagate
to any other copies of it.  The odds are slim, but still probably
better than your main system being hit by lightening.   I had
an amanda system running to tapes before setting up backuppc and
have continued to let it run independently for my most critical
filesystems.  I hope to never have to actually restore from
tapes again, though.
