CD is a good medium to archive on, but remember too that it's far from
permanent. Scratches, changes in humidity and temperature, and natural
defect growth can all effect the stability of CD-Rs...I think they're rated
only for 20 yrs...not that it would matter much...I doubt that anyone will
have a data CD reader in 20 yrs.

Personally, I back up on tape every night and archive onto CD-R. I also
duplicate every archive CD and keep the copy off-site.

Oh yeah, four years ago I used to use 650-meg magneto-opticals for this but
my drive started to fail, and I was able to transfer everything to CD-R
before it went completely...now it's useless and virtually unfixable
(Olympus, the manufacturer, can't/won't fix it). Remember Apex 4.3-gig MO
discs? (*shudder*)

That was a 1-to-1 copy process and time-consuming (~30 MOdiscs = 60
CDs)...I'll probably start re-archiving CDs onto DVD-RAM soon....at least
I'll be able to get 8 CDs on a single disc.
