Backup failed (a2277)..tried multiple, different disks - does not seem to be HW related. Help!

 For the past week now, I have received a backup fail message (a2277) - with no indication of an underlying cause. I've tried 1) backing up from different disks; and 2) backing up different files. All led to a a2277 message, with no additional description / information. Any help would be greatly appreciated!

 

Thx.
