Hi Deborah,
I look forward to reading this string as it develops.
FOR IMAGES:
I am an advocate for near-line storage- SANs or NAS devices. This
option can cut your costs dramatically (or somewhat anyway) and can
help you in delivering files over the network. Usually after the
databases have all the jpeg and reference files they need, larger tif
files can be near line or off line. My past life as a system
integrator always makes me question the ROI of housing large image
files on a fully functioning server. An honest assessment of which
files will actually be requested over the coming year or two, is a
good one and may save you back-up headaches as well as network time
and money.
As you know the industry is moving fast in the direction of back-up
servers. But I feel tape backups will be around for a while as well
due to the fact that many firms have policies stipulating a copy of
the backups is to be housed off-site.
We are also keen on the idea of a fast server with limited space.
Servers such as these can be deployed locally for the small group of
users that need a given set of data/files. With a small deployment
(less than 1TB) these size servers are easily backed up with a
desktop type tape drive or a smaller backup server. Beyond price, a
further advantage of a smaller server is that the users are forced to
manage the files - especially archiving older files. For tape
backup, I recommend AIT. AIT-3 and AIT-4 are the current flavors.

Hello--
We've been having a discussion here about the exploding costs of
network backup, as digital image collections grow, and also about
potential future costs such as format migration. While the cost of
backup tapes tends to go down as time passes, the formats are also
continually being improved, with new formats then going back up in
price, so the costs over time don't really decrease. And, of
course, as we continue into digital imaging full speed, we're
creating assets that are never going to be deleted.
I'd be interested in hearing about any creative ideas people have
implemented or are thinking about. I've floated the possibility of
adding a fixed percentage to any digital imaging special project
budget in order to create a "longevity endowment." Not at all sure
if that's workable, but it's an idea out of the box.
Thanks,
Deb Wythe
