Gianni,
If the data does not have to be electronically accessible as a whole,
I would guess tape backups would be the best medium. This is what my
company uses for 30 day rotating backups and permanent quarterly
backups of our multi terabyte cluster server. Supposedly the cluster
server technology is nearly infinitely expandable. I don't know too
much about the details or the major players in that market, but I
could find out from my local IT professionals if you would like.
Probably would get an excellent response to this sort of question
from a newsgroup based on LAN technology. Either way, your certainly
in the territory of business class storage. There are a large number
of data storage companies out there for exactly what you need. No
idea what the fees would be, it probably depends on what sort of
access is required - speed, frequency, number of users, via internet
or private connection, etc. It buys you professional management and
protection - data security, well who knows? I'm sure it takes a lot
of research and some onsite visits.
If you don't mind me asking, and assuming that if you tell me you
won't have to kill me after, what do you do with such data? Can it
be processed to some final more manageable form and then discard the
raw data. If it's special interest research orientated data, perhaps
you could find a sponsor such as a large university.
