Hello,
The fact that you are able to backup some file systems leads me to believe 
the configuration is almost correct and the time-outs  on the group is 
causing the backups to fail.
Also note that NDMP only supports level backup to my knowledge, forcing 
incremental via group attribute may  result in FULL backups.
I am glad you have a completed backups, make sure you also set correct 
application parameters in client attribute, this are documented under 
admin guide.
HTH

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.

    NetApp's dump command can take a lot of time before it will start 
sending out data. The time is proportional to the number of files on the 
volume. On a volume (connected to a FAS3050) which had ~5M files the 
backup failed when the group inactivity time was 120 minutes and I had 
to set it to 0 before I could get the volume to run full backups.
