I am pretty much working blind here, trying to back up some new Lotus Domino 9 servers running Windows 2008 R2.
The backup job keeps backing up the same 8 Domino save sets over and over. Every save set succeeds, but as soon as one batch of 8 finishes, another identical batch of 8 starts.
After 11 hours or so, the backup fails:
* server1:NOTES:D:\Domino\Data savegrp: suppressed 37 lines of output.
* server1:NOTES:D:\Domino\Data
* server1:NOTES:D:\Domino\Data System error: XBSA-1.0.1 LNMs_2010.Build.231 4904 Thu May 29 06:32:45 2014 _nwbsa_close_create_object_session: System detected error due to: savefile_fini() failure, typically caused by bad network hardware (NICs, routers, etc). Operation aborted
* server1:NOTES:D:\Domino\Data
* server1:NOTES:D:\Domino\Data Backup of connecting directory (browselist) failed
* server1:NOTES:D:\Domino\Data 71196:nsrdasv: Backup of connecting directory (browselist) failed
* server1:NOTES:D:\Domino\Data Child process 4904 returned with failure -256.
* server1:NOTES:D:\Domino\Data 82353:nsrdasv: Child process 4904 returned with failure -256.
I probably have something misconfigured, but I have no idea what.
You should use name reflecting interface you can use from that client. Otherwise it might use wrong interface (eg, which is not reachable) and then you may get what you see.
One of the reasons you are seeing repeated save sets is a result of the Client Retires value. If it is > 0, then if any of the 8 NMDA threads failed as the log excerpts describe, then all 8 sessions will be restarted.
You may want to consider:
Changing Client Retries to 0 to help isolate your backup failure.
OR
Leave Client Retries = 1+ in order and enable Checkpoint Restart for the NMDA client, This will allow the backup to pickup from where it left off and can at least protect your Domino data.
ANother item that I can see is the browselist save set appears to be failing. The browselist architecure changed in NMDA 1.2 and you need to ensure that it can always have an open device session so it can get saved throughout the backup. This differs from NMDA 1.1 and now 1.6 as browslist gets backed up after the data as opposed to 1.2 where it gets backed up concurrently.
Also, you may want to consider increasing the debug level and using NSR_DPRINTF=TRUE. If the backup is failing as a result of a communciation based issue, this change will help expose that error messaging for a root cause.
Review the log that has the 4904 PID in its name. It should conatin the reason the backup exited.
Keep me posted as I am one of the EMC Support SME's that focus on NMDA\Domino issues.
Is there any reason you didn't try the most current NMDA 1.6? I believe I had to upgrade ours to 1.6 to get the DAOS backups to work properly (which may not be a big deal if they aren't using it).

Well, I upgraded NMDA to 1.2, and the backup worked!
Again, I'm working blind here, using software that was in the customer's repository. All they had for Windows X64 was the 1.1 version.
I ended up downloading the 1.2 version from EMC's website and installing it.
