Check if the volume you are trying to backup is not 100% full.
this often creates error 99

Are there a lot of files on this volume? I have seen this on my EMC Celerra
NAS and after applying some EMC recommended directives to the policy, not
only did performance improve but no more error 99's or 229's.

Another thing to look at -- are you running more NDMP jobs at a time than
the NAS can handle? I know on the EMC celerra there are only 4 threads available
for NDMP backups, if you try to run more you will get status 99's (if you
drill down you will see something like "failed to allocate pax thread....")

I know at Oracle we couldn't run more than 2 NDMP streams at a time against
sata based Netapps or we would see I/Ocome to a screeching halt.. (we were
using NDMP appliances that moved data very fast)

You may need to get with Net App and find out what they recommend for large
volumes and/or volumes with large numbers of files. Here are the settings
we used for EMC celerra: (don't trust these for use with netapp obviously)

set DIRECT=y
set HIST=y
set TYPE=dump
set OPTION=NT
set SNAPSURE=y
set UPDATE=y
/myVol

(volume must go after all the directives)
