The problem with putting floppy images on a DVD is
that if you lose
or destroy that DVD you lose a ton of data
Well, rule #1 is never have a single copy of backup data.
Rule #2 is have an off-site copy.
That single DVD is going to be a heck of a lot easier to migrate
to the next generation of media than trying to re-read those floppies
again (if they are still even readable).
A single copy of something on aging media is a problem I face at CHM.
It's what I call a 'latent archive'. If you don't actually RECOVER the
data on an old tape or disk, you can't be assured that you actually
have anything other than the physical object.
