Dana,

It seems that you suggest you know something that the gang I know at
LOC and most of the National Libraries don't..

Quoting "Dana H. Myers" <dana.myers@xxxxxxxxx>:

RAID is NOT the answer.. We've had RAID subsystems go south on us and
take out at one blow 4 drives. Its funny but I mentioned this just last
Summer while at a meeting of an EU project.. and within a month a controller
in one of the institute's subsystem went Zonk, knocked out multiple drives..
they were lucky, 2500 EURO later they were able to reconstruct their database..

Archival storage is a bigger problem then its ever been.. My little
company has multiple TB of live data.. constantly growing.. where can we
store it? Tape is not a good long term solution..
Now we have 100s of machines and redundant Internet links and even 2 locations
in Munich.. so we might be able to stem a bit of the tide.. and maybe
with luck hold things a bit together.. but only by luck.. But what normal
photographer has the technology and data budget? And what consumer?

And what we can do does not scale indefinitely.. its NOT a solution for
big archives.. Its really non-trivial. 

Luck too is not a good thing to rely upon when talking about cultural
heritage.

Right now the easiest and cheapest "solutions" I know of are based upon.. Oh
no.. film.. Yes Microfilm! With 600+ lp/mm resolution of microfilms (1:1000
contrast) one can store quite a bit and we kind of think we might understand
how to get some good storage lifetime out of film...
