RE: OT: tape backup

[Paul Bunn <Paul UltraBac com>]

I think it fairly clear from my previous post that I was quoting pricing on a
single tape cart -- not $/GB ratios.  If you want the best value $/GB, then
probably LTO with its 100GB native capacity makes better sense, or hell, maybe a
DST with 660GB native cartridges at only $445 each is a bargain (of course, you
would have to use a lot of tapes to recoup the original $130K investment -- that
does tend to put off quite a few people).
As I mentioned in my original response, it very much depends how much you are
willing to spend, how much capacity you need, and how long your backup window is.
Other factors also come into play -- how many times can a tape be *reliably*
reused, and the overall reliability of the drive.  MTBF figures are usually quoted
by the manufacturer, often using the technical "finger in the air" method of
measurement.

BTW, I think my eyeballs are just fine, thank you.

You better get new eyeballs. DLT is cheaper as is M2 per GB.
I don't use AIT so I won't comment but a simple search on
pricewatch will tell the true picture. If you want the best
deal on $$/GB, use CD-R, then 8mm 5GB.
