NDMP backup of EMC NAS just started to fail with 233/medium error/99

[rock7171]

It fails when doing a Full (Incr completes) and it fails when it gets to just over 265,300,000 kilobytes completed.  the last two times it failed exactly at  "265,307,904 kilobytes and 249000 files  (it is a 2TB backup when it completes)

I think there is a file that is causing it to fail but don't know how to trace it down

What EMC box do you have ? 

Name and possible firmware level.

Please see step 8 "retriving the server_log" as it may contain a clue to the error:

How to troubleshoot NDMP Backups failures when status code 99 (or other NDMP backup failure) is reported. Includes logging instructions.

Does the EMC box write directly to its own tape drives or does traffic pass via a Netbackup media servers ?

Please also ensure you don't run more than 8 concurrent operation - its a limitation of the NAS device.

It backs up to Winchester Disk located on the Master.  We have three NDMP polices on this Master for NAS device. Two backs up to the Master Winchester Disk and one backs up to Winchester Disk on a Media Server.  Out of the Three this is the only one that is failing with 233/99..   It is the same EMC box for all three.

We have the same setup at two other locations.  We do get 99 errors every so often on all our NDMP backups and normally just restarting the backup gets pass the error
