You may get slightly better performance if you backed up the NetApp directly 
from the Win2K master/media, so it had one less host to go through for backup. 
Just a thought, though I'm guessing there's a reason you're proxying through 
the Linux box.

are you running NFSv2 or NFSv3?

just curious because we found that the performance of NFSv2 on linux is
terrible (in general)..   once we moved them over to NFSv3 we were able to
get a lot more IO performance out of our linux boxes..
