Monthly Full Backup failed with error code E000FE36 in the past 2 months ?

Hi,

I'm running Backup Exec 2012 v14.0 Rev. 1798 and for some reason I got this one monthly full backup job that is always failing with the error code E000FE36.

Here's the error message code V-79-57344-65078:

Upon browsing to the directory that was mentioned above, it is still exists and already there. no one deleting or modified the directory in the same server where BE 2012 is running.

See the directory properties below, it is created long time ago:
