This will not help if all of your copies age fast. The key is to
define in advance what reliability, what archiving period and
what maintenance effort you want to have.
If you want to go with one medium, zero maintenance and several decades,
MOD it the only choice.
If you can tolerate high maintenance (yearly checks) and multiple
media sets, go CD or DVD, but don't fotget to chcek them all each year
or so. And store them correctly. And select good media (pretty hard)
Phthalocyanine dye and hardened surface is the trick. Not that hard at all
to select. See for example Maxell DVD-R Pro.
Further for the price of one 9 gig MO disk you can get DVD-R disks from 15
different manufacturers, which eliminates relying on a single vendor's
quality control.
and butn them right, since others could leave you without your data
even faster, even with multiple copies.
Professional archiving tape is somewere in between but too expensive
for most users.
Uh, Arno, DLT is commonly used for archiving by rather large players who may
be assumed to have the resources to do their homework, IBM claims that it
will last 50-100 years if given reasonable care and it's a HELL of a lot
cheaper than MO. The largest available MO media was 9.1GB last I heard.
Best price I can find on it is 55 bucks a shot. DLTIV tapes cost 25 bucks
a shot and hold 40 gig. The best price I can find on a 9.1GB MO drive is
1500 bucks but a DLT1 drive costs 650 and a DLT8000 around 1100. So DLT
seems a _lot_ more attractive than MO unless the storage duration is really
long.
MO I'm sure has its use, but its limited capacity and high cost make it a
niche product.
But this is all totally ludicrous in response to a question about a Zip
drive.
