Dear Experts,

I am looking for your advice on below topic.

We have NDMP backups are configured with SP Server (7.1.6). The Netapp ( v8.5 , 
7 mode) setup would be like, the remote site production filer has been syncing 
the data to DR site Filer (snapmirror).
The TSM NDMP backup is configured from DR site. The tape drives are zoned to 
NAS filer and volume backups are scheduled from TSM schedule (backup node ).

Few days before, one of Netapp vol usage was grownup to 300 % ( earlier 4 TB,  
current size - 8.6 TB and dudup is 64% so, current size is around 14 TB).

After the data increase, the specific volume's backup started to failed in all 
methods like,  full, differential and with out TOC and with TOC.   The backup 
is failing in varies stages like after the completion of 20, 40 , 50%.

Any advice ?
