Gary,

We've been using DLT for a few months, now, and have found it reliable,
fast and easy to use.  Our 996 system backups went from 100+ 2400' reel
tapes and 7 hours (2 drives in parallel) to 3 DLT cartridges and 3
hours (3 drives in parallel).  With each drive on a separate SE-SCSI
interface, we achieve roughly 30 Gbytes/hour throughput with drive
compression enabled and 2nd-level software compression enabled (we use
Orbit's 'Backup/Plus' - beside Turbostore, this may be the only backup
software which supports DLT, AFAIK).

We're taking a look at moving from DDS-2 to either DDS-3 or DLT drives for
tape backup.  I've got the performance and storage specs on the drives, but
am wondering if anybody on this list is using either format and has any
comments regarding reliability, tape life, etc, that they would like to
share, for either format.   You can email me direct if you like.

Oh, by the way, we are looking at this for our non-HP3000 platforms as well
as the HP3000 platforms, so I'm not limiting this to just what the 3000 can
support.

Thanks,
