Mario,
Sorry I didn't get back soon enough.  I ususally look at this
list about once a week.

To answer your question, we use NDMP over Gigabit via a private
subnet to Quantum/ATL GigE P7000's with LTO drives.  We are just
getting drive performance of 50GB/hour.  We have been told that
if we move to Jumbo Frames, we should see a great increase in speed.
We have plans to test Jumbo Frames early next year.  I know of 
another TI site that is using Fiber Channel direct attached LTO 
drives who is getting 60GB/hour.  These results, of course, are 
on  Network Appliance filers.

Your milage may very.  Personally, I believe NDMP is the best
way to backup NAS.  NDMP version 5 promises multiple streaming.
