These numbers are strictly guesses. DVD-RAM has only been in use a
few years, and that's the only valid data if you really care about
your data integrity. Any data from 2 years ago is somewhat
meaningless on current backups, since both burners and media have
changed in that time.

There's not a digital medium in the world I'd count on to last 100
years, except maybe punch cards.
