Not need AOFO exception on job completion due to audit issue

Dear Symantec,

I was getting error for "V-79-10000-11226 - VSS Snapshot error. The Microsoft Volume Shadow Copy Service (VSS) snapshot provider selected returned: "Unexpected provider error". Ensure that all provider services are enabled and can be started. Check the Windows Event Viewer for details. "


I created a new backup job with AOFO unchecked but still getting the same error. I don't want the above exception for my 
backup job due to my audit issue. Can some one help me out to get rid of this.
