After installing Norton Ghost 15 onto a new Dell Studio XPS 7100, the backup process failed sometimes leaving the following message in the Event Log:
Error EC8F17B7: Cannot create recovery points for job: My Computer Backup.
Error EC8F03ED: Cannot create the recovery point.
Error EBAB0013: A test that safeguards the integrity of the program failed unexpectedly. CHECK failed, Computer::CreateImageFile: .\Computer.cpp(1453): guid != Guid() && sequence != 0xffffffff. (UMI:V-281-3215-6071)
After a long investigation I could isolate the problem as being an incompatibility with Dell Data Safe Backup, a program that comes installed in Dell systems and, even if not activated, has a process running in the background. After uninstalling this application and two other related ones the problem stopped.
