For the last 2 months my nightly backup has been failing when it attempts to
backup the First Storage Group. The error is not very descriptive, so I'm
not sure what to troubleshoot. I have tried uninstalling and reinstalling
BE9 with the latest downloaded release, uninstalled and reinstalled the
Remote Agent on the Exchange server, etc. to no avail. Does anyone have any
other ideas for me to try please?

Here is the error from the job log:
