NDMP Restore completes but has 0KB files

Hi,

I'm trying to do a restore from a NDMP Restore. The restore job completes but has restored some of the files which were shown in GB as 0KB. The original size of job should be around 50 GB but it is restoring only 15 GB.

NetBackup version 7.1

NDMP -  NetApp Filer 8.1

We're not restoring to the root volume.

We are unable to restore certain files.

It doesn't support restoring from 8.1 Filer to a lower version. We have only one 8.1 filer.

Disabled/Enabled DAR with no luck.
