Yep.  But if you're gonna go the paranoid route you also need to
consider fire and should be mailing your tapes/dvds/hard-drives to an
offsite backup location as well.

It's all about the trade-offs I agree.  The good news is that in 20
years of unix work I've yet to type rm -rf /.

I actually think there is a way to do a write-once mode to a HDD if you
like too, but I can't remember where I saw that operation before.  If
nothing else, use dd and the right starting block number and treat it
the same way you would a tape or DVD (IE, no real file system).

Don't forget fragile and subject to aging.  But they do fit in a
fire-safe nicely!
