I have not found a way to back up NetApp NFS shares on a Win2k box without
going through another Unix server. If anyone has found a way to do this I
would certainly like to know. I have heard that with the next release of NBU
we will be able to do NDMP third-party backups to the drives attached to
media servers. I am certainly looking forward to that...

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..
