Ghost 12.0 , Data and File BU not completing

I am getting the following error for my regularly scheduled BU for Data and Files.  Full C:\ BU has not issues and running fine.  Problem started about a month ago (scheduled BU is weekly) so has missed several BU.  Is there somehting I can do to track down more details on the problem and resolve to resume BU or should I delete this job and start over with a new one?  

 

Thanks,
