Note that there is/was another similar job running at the same time, same source/dest NAS's but different shares, it is still running.

There is no RN316 strange log content around the time of failure.

What does it mean?

Re: Backup failed - due to unknown reason. NV+

I'm not sure what it means.  Have you tuned the SMB settings on the RN316 with SMB plus?

 

I am thinking that you might want to try using rsync instead of cifs, and see if that has a similar issue.

Re: Backup failed - due to unknown reason. NV+

For the record, I reran it after source & target were rebooted, it completed normally.
