Failed Backup on Exchange 2007 CCR Cluster

I have been able to backup my CCR cluster fine.  I am getting this issue below when trying to back it up.

Backup- \\INDYMBX\Microsoft Information Store\Eighth Storage Group
V-79-57344-34110 - AOFO: Initialization failure on: "\\INDYMBX\Microsoft Information Store\Ninth St... Snapshot provider error (0xE000FED1): A failure occurred querying the Writer status.

I had a similar situation about three weeks ago, but it wasn't erroring on the same storage group.  According to the documentation that I saw, the only fix was to dismount the database and re-mount it.  I ended up just rebooting the active node and that cleared up the problem.  I have two questions:

Is this the only way to correct this issue?
Why is it happening?

Any assistance with this issue would be appreciated.

Thank you.

Why are you using AOFO on the Information Store?  Turn that off, and use the native BackupExec Exchange functionality.

I don't have the AOFO enabled in the job is the wierd thing.  Am I missing something?  See the attached screenshot.
