3570 -> 3590 -> LTO tape drive

We've done some shuffling around of tape drives here.  We are quite
impressed.  We knew the 3590 would beat the 3570 but we were surprised by
how much.  What really floored us was the new LTO tape drive shaving a few
hours off of the backup that our 3590 did.

Stats:

I) Old
A)  Backup of primary Domino server.  Used 3570 on 830 QPRCFEAT=23D1, using
6534 storage controller.  Ran from 22:27-05:27 or exactly 7 hours.
B)  Backup of ADSTAR PC backups stored on 400.  Used 3590-E on 830
QPRCFEAT=23D1, using 2749 storage controller.  Ran from 00:22->09:04 or
just under 9 hours

II)  New
A)  Backup of primary Domino server.  Used 3590-E on 830 QPRCFEAT=23D1,
using 6534 storage controller.  Ran from 22:11->23:39 or just under 2.5
hours.  A savings of 4.5 hours!
B)  Backup of ADSTAR PC backups stored on 400.  Used LTO tape drive on 830
QPRCFEAT=23D1, using 2749 storage controller.  Ran from 00:22->06:30
(didn't have enough tapes - ADSTAR data is already compressed) and from
07:58->08:42 or around 6.75  hours.  A savings of 2.25 hours.

This significantly reduces the time that our primary Domino server is down.
Also, we were getting close to the 10 tape limit in our 3590-E but our LTO
tape drive is only using 4 out of the 7 tapes, so our ADSTAR capacity has
grown.
And, the LTO tape drive, once we got it configured, so far has not given us
the problems like the $%^& 3570 did.
