If WOFB is enabled, then yes, NBU will try and use it.
You say you do not have WOFB enabled for this client.
Did this clients incremental backups work previously (like 2 weeks ago), and if the DID work, was WOFB disabled at that time.
DO NOT start making changes to NBU until you work out what is going on.
You have a single failure - if this clears on it's own, but you start making changes, the change you make might be wrong and cause more failures.
I am not saying a change will not be required, it might, it might not but there is not enough info to determine this yet.
The worst thing you can do, is start just making changes.
You should know, because it should be in the system documentation, if WOFB backup should be enabled for this client or not.
Looking at what I know ...
If WOFB was enabled when you had the failure, and this is not a Windows cluster, then it's
back to the bpfis log for answers.
If WOFB backup was NOT enabled, then as you have a 156 error I suspect this is a cluster and the TN explains the reason for the failure.
If WOFB was enabled, AND, this is a cluster then it could be either the cause in the TN, or, we need the bpfis log.
The most important thing is that you do not start making changes, the incr failed, ok not good, but the full appears to work, so at least temp. you can run the full to get the backup.
Trouble shooting should NOT start by making changes, it should start by looking for and finding the cause, without making changes. I admit sometimes this is not possible, but it is the way an investigation should be started.
Trust me, I see very very broken systems, caused by changes being made without a very good reason.
The conversation goes like this ...
Me. What was changed
Nothing.
Me thinkng - that's odd, the error we see now is not the same as the error that was originally reported ...
... then an amount of time later we prove that x, y, and z changed.
In severe cases, this can take days/ weeks to find, so a problem that should have taken perhaps a few hours, or a day or two to fix, takes weeks, simple because mutiple undocumented changes were made that for some strange reason, nobody can remember making.
