Backup File Error Messages
When you attempt to restore a backup in Windows XP created using the MS backup tool (NTBACKUP.EXE) in Windows 7/Vista/2K/XP/2003, you may receive one of the following error messages:

- "CRC (cyclic redundancy check) error".
- "The backup file contains unrecognized data and cannot be used ntbackup or xp ".
- "The backup file is unusable. You must erase it, or choose another file".
- "The fixed media is full. You cannot back up all of the specified data to this disk device. The backup operation will stop".
- "An inconsistency was encountered on the requested media".
Modern versions of Microsoft Windows operating system have BITS (Background Intelligent Transfer Service) components. BITS components lock the Qmgr0.dat and Qmgr1.dat files, when it is working. If you are making the concurrent backup (using the NTBACKUP.exe) then these files may not be opened and therefore the backup can not be created and your BKF file becomes inconstant and damaged stage. When you performs the restoration process, the BKF file shows following error message:
- Warning: Unable to open file. qmgr0.dat is skipped.
Reason: The process cannot access the file because it is being used by another process.
Or - Warning: Unable to open file. qmgr1.dat is skipped.
Reason: The process cannot access the file because it is being used by another process.
