Our experience with the different libraries and backup software comes
down to network speeds being a major part of the equation.

LTO and SDLT drives are fast devices.  But in many cases on my 100M
network and some of my older client machines, I can't push data to
these libraries fast enough to keep them streaming.

I have recently been evaluating Avail's Integrity backup software and
using a SDLT library.  It seems that the SDLT has a very large cache
in front of the drive and with Integrity I can migrate from my NAS box
(where I have all of my clients backup to first) and then roll that
backup off to the tape library.

The speeds are great and the SDLT is really screaming.

I've done a number of restore "tests" to see how fast I can get the
data back and that's been painless and quick too.

What I'm trying to say is that the overall network speed has a lot to
do with your performance and the Cache on the SDLT makes a big
difference. And I like this Integrity product too.  I know that
Overland also has SDLT libraries and I have been very happy with their
products!

Hope that helps some.
