I have a policy that backs up both nodes of a SQL cluster in an active / active configuration, all of the visible drives on the active nodes are backed up successfully but the "Shadow Copy Components" job fails on each node with a snapshot error (156).
Here is the sanitised output from the job log and I've attached the output from the bpbkar log on the client in full.

Is there anything in the log that suggests the cause and can you point me towards a solution?
Thanks,
