After several stops and starts, I finally managed to get the SNAPDIFF feature 
to work on our 6.1.3.4 server.  Client is Win 2003 server 64 bit 6.2.0.1. We 
have been backing up a large Windows file and print store with 5 or 6 servers 
and having problems with volumes that were too large and with too many files.  
These are being migrated to CIFS on Netapp.  The first of these was moved a 
little over a week ago and was backing up fine using the SNAPDIFF feature until 
Monday night's backup. This backup failed with:

ANR0480W Session 503377 for node DPCRCFPUT01 (WinNT) terminated  - connection 
with client severed. (SESSION: 503377)

This has been failing ever since; gets the error, restarts then gets the error 
again after about 10 minutes or so until the window expires.

This fails consistently with both the scheduled backup and with the command 
line when the -SNAPDIFF option is specified.  Remove the SNAPDIFF and 
everything consistently works fine, although it takes a bit longer.

Any ideas out there?
