Which NFS were you using?

If the traditional one based on UDP, I concur that you could/should expect challenges. However, I'd expect most propblems to disappear when using the new NFS based on TCP.

I've done some of this kind of backup to NetApp Filer using their NFS and had no challenges. Then again, their NFS is also certified for Oacle RAC.
