Odd VBR Error

[jgremillion]

I have been receiving this error when trying to backup and when replicating a few VMs. Any ideas as to the cause and resolution.

It is hard to say anything from session summary without seeing full job logs, but it sounds like there are some issue with accessing VM files for this specific VM or LUN. Please contact our support team for assistance.
