Dear NBU champions smiley

I am using NBU 7.0.1 on master server win 2k3 R2.

NDMP client -- EMC celera

backup selection in NDMP policy --

  • /SSGROUP   (1.4 TB)
  • /RTGS          (500GB)
  • /VVRTGS      (300GB)

I am facing problem only with /SSGROUP as its completes only in 4th or 5th attampts (with below errors) & every time it writes 30% 40% data on tape , other two streams completes with on issue.

4/5/2011 3:54:51 AM - Error bpbrm(pid=5952) db_FLISTsend failed: file read failed (13)      

4/5/2011 3:54:57 AM - Error ndmpagent(pid=8992) terminated by parent process        

4/5/2011 3:54:57 AM - Error ndmpagent(pid=8992) NDMP backup failed, path = /SSGROUP      

4/5/2011 3:54:58 AM - Error ndmpagent(pid=8992) NDMP_LOG_ERROR 0 Backup is aborted.       

4/5/2011 3:55:54 AM - Error ndmpagent(pid=8992) connection 00000000015137B0 ndmp_message_process_one failed, status = 18 (NDMP_XDR_DECODE_ERR)

As per wrobbins suggested, splitting the volumes up could be the best option.

If not, you might want to try this setting:

I had seen it working for both Netapp or EMC filer, not entirely removing the symptom, but some streams that used to error out with status 42/41 tend to complete.

can you split backup into multiple streams, i.e. /SSGROUP/somedir and /SSGROUP/otherdir

As watsons  &  wrobbins suggested,

I found in /SSGROUP there are total 33 dir hence i modified backup selection by each dir 

but still one stream taking 2 attampts to finish with same error as mentioned below & other 32 stream finished in 1st attampt without any errors

/SSGROUP/Accounts & Finance

After that

I also worked as per TN and created NDMP_PROGRESS_TIMEOUT & restarted job.
