Netvault Backup to filer attached library hangs on writing index

Situation:
When opening the Binary log, there is no apparent error: it only shows that the transfer of the main data has finished, nothing more.
The only way to find out what is going on is to gather trace files from the server and the client.

the clue traces are the plugin's trace from the client (in this case the nvfs229.log) and the plugin from the device, in this case nvndmpdevmgr4618.log.

 

When checking the logs, the first one to check is the nvndmpdevmgr4618.log, filter to error mode (ctrl-2), and follow the log near the end: all the way down you will see a discrepancy right away with the time:
0 FILESYS 7908 31 2 11356438014 Failed to open E:/BakBone Software/NetVault Backup/config/devmgr.cfg error The system cannot find the file specified.
0 DEVMOVER 7908 666 0 30003566999 Failed waiting for mover to go inactive

As you can see here the second error indicates when the job aborted, if you filter all the way down to ctrl-8 and go deeper to see where time discrepancy is, you will find the following:
3 DEVMOVER 7908 788 0 12454686254 TRUE = gtMoverContext.bBusy
3 DEVMOVER 7908 790 0 12454686254 TRUE = gtMoverContext.bListening
3 DEVMOVER 7908 789 0 12454686254 TRUE = gtMoverContext.bCon
