Weird RPC error on Exchange 2010 DAG member Backup Copy Job

[Dave-Departed]

Got a support case open for this one (00466465)...

We've had some troubles with our Backup Copy Jobs recently, and all seem to be resolved, apart from this one job. It's an Exchange 2010 DAG member VM, and the regular Veeam backup works fine.

However, when the BCJ runs, I now see:

21/11/2013 11:56:59 :: Error: Client error: The RPC server is unavailable.
RPC function call failed. Function name: [DoRpc]. Target machine: [localhost].
Agent failed to process method {Signature.LoadFromWACache}.

Anyone got any idea what this is?

Thanks in advance

Dave

Dave, do you have Veeam B&R v7 R2 update installed?

[Dave-Departed]

Indeed we do, Foggy!

Ok, then let's wait for what support can suggest after reviewing the logs.
