Stan,
        We're using NDMP and 7.1.1 haven't noticed any difference from
6.1.3 yet. We have NetApp connected to dedicated library right now but
intend to connect to fabric and use shared library in the near future. 

Regards
Bob

hardware configuration, you may also need  the SnapImage module, which
is also an extra cost item. If you are going to back up to a tape
library that's connected to your Legato server OR to a storage node, you
need SnapImage.

You need one NDMP license per NAS device that you want to back up.

Is it easy to restore files? I suppose so. I use NDMP with NetWorker
6.1.3 which does not support file recovers, just the entire disk volume.
Since each NAS device has its own way of handling NDMP, you absolutely
need to read the documentation for your device in order to get NDMP
working properly. The NetWorker Administrator's guide has good info on
this subject. Consult with your NAS device vendor too for vendor
specific info.

The comment about NDMP restarting from scratch if a glitch occurs during
a backup is something I too have experienced, but not often.
