Norton Ghost Error Message Question

I have received this error with Norton Ghost and I’m not sure what to do with it:
Error E7D1001D: Unable to open //./SymantecSnapshot0/encrypt/<Filename>" in BESR
Problem
A Symantec Backup Exec System Recovery (BESR) backup job of an encrypted file with file and folder backup fails with the error "Error E7D1001D: Unable to open //./SymantecSnapshot0/encrypt/
Error
Error E7D1001D: Unable to open
Have any ideas on this? Thanks in advance.
