We are putting in a new server in about a month.  We are going with LTO,
the drives are anywhere from $2000 to $5000 depending on internal/external
and capacity 100/200 or 200/400 (the larger number is compressed capacity)
Kind of fun really sitting down with the major vendors and going over
everything.  Got that kid in a candy store feeling.  I guess one point I
like of Ultrium over the SuperDLT is that the Ulrium media is only 1/2 inch
thick, so it will take up less space in our tape case.

Backups are spendy, as someone said earlier it kind of depends on the
importance of your data.  For our mission critical we use 24 daily tapes, 10
weekly and then a monthly.  That adds up at $70 a pop.

Actually, I think DLT IV tapes can do 40GB, but it depends on the
drive.  A DLT 7000 drive can do 35/70GB, and a DLT 8000 can do 40/80GB. 
I think there are lower-end drives that only handle lower densities.

People with money are spending it on LTO Ultrium and Super DLT drives
(among others, I imagine).  They run up toward 150-200 GB native
capacity, but I'm sure prices are through the roof.
