Hello,
You need to look at NDMP backups top to bottom, how the server is 
configured, FC, Tape drives on the filer, NDMP version, NDMP client and 
Group configurations  etc to have an sucess.Make sure you have enough temp 
file space on the backup server for NDMP to use.I would isolate NDMP 
backup to group by itself ( set  Group inactivity time-outs to 0, as it 
may take long time for file history etc ).
Work with EMC\Netapp  to identify the problems, turn on extra debugging.
One thing to note is NDMP backup licence for Networker is any thing but 
cheap.
I have had no major problems with NDMP backups running on Windows server 
and FAS 3050C.
HTH

We just got our first filer. It is Netapp and I am using Networker with 
NDMP and not having very good luck so far. I was just wondering about your 
comment about netapp/networker combination. My tape drive is attached to 
my windows networker server. Most times when I run a backup a few volumes 
will complete successfully and then it seems that something goes to sleep 
and the tape device sits at writing/idle.
