Any reason why you did not include the timestamps in Job Details?

This will indicate if there was a long delay at some point and if bpbkar was hanging or terminated.

bpbkar log on the client may help.

Create the folder under /usr/openv/netbackup/logs and add 
VERBOSE = 3 
in client's bp.conf.
(I know others will ask for level 5 log, but then the logs become so big that you will need to open a Support call where large log files can be uploaded.)
If we cannot see where the problem is with level 3 log, we will ask you to increase logging to 5 and to open a Support call. 

 Please also have a look at /var/log/messages during backup time for any clues.

Hi,

Tks for your update.kindly check the below logs

and i am facing issue with onlt Incremental-daily backups.all other backups are completting successfully.

kindly check attache Logs.

Is this backup still running or has it failed?

There are no errors in this log and contains entries from 09:46:47 to 09:46:54 - 7 seconds...

If the backup has failed and there are no bpbkar processes running on this client, then something/someone else (outside of NBU) has killed the backup process.

Curently this backup is scheduled but job is failing.so i made verbose entry and restarted.The above attached log  is generated that time.Its an incremental backup.and it is scheduled 1 hr frequency.All full backups are running fine for this client.
