Norton Ghost error message after finished backup

I did a system backup on a partition drive with a BD-RE DL 50 GB disc formatted as only to be able to write once.

 

After the job finished and the disc poped out I got this error message:

 

Error EC8F17B7: Cannot create recovery points for job: Drive Backup of (C:\), (D:\).
    Error EC8F03F0: Cannot add the new recovery point to the history of this drive.
        Error ED800012: The internal structure of the recovery point file (CRC Validation) is invalid, damaged or unsupported. (UMI:V-281-3215-6071)

I don't know if the job is succesull despite the error message.

 

Before the backup:

 

Info 6C8F1F63: The drive-based backup job, Drive Backup of (C:\), (D:\), has been started manually.
Details:
Source: Norton Ghost

 

All three files are on the disc, so it is complete, although I don't know what the recovery point has to do with all.

 

I used a password...
