Windows NTBackup is a built-in command-line utility of Windows operating system that can be used to backup files to different storage media like, CDs, DVDs, ZIP drives, tapes, and others. But many times, this is observed that storage media problems often corrupt the BKF files created by NTBackup program. So even if you verify the backup, further media malfunctions can cause damage to the file. In such cases, data recovery is possible only if you have another backup to restore or apply a BKF Repair tool that can repair the file.
As an instance of these problems, let's consider a scenario in which you create a BKF file on a CD using Windows XP NTBackup application. For avoiding any further problems, you verify the backup and expect it to work at the time of restoration. After a major data loss event, when you try to restore data from the CD stored BKF file, it behaves contrary to your assumptions and shows file corruption symptoms.
Further, when you try to copy the same BKF file from the CD to your hard disk, it pops up another error message that reads:
“Error copying file or folder
Cannot copy backup_file_name.bkf : Data error (cyclic redundancy check)”
Explanation
CRC or Cyclic Redundancy Check is a bit, which is used to ensure the integrity of data in a file when it is being transferred. It is a typical check procedure that can determine whether or not the data has been damaged. CRC errors usually indicate that the file being read by the computer is corrupted.
Note: Apart from software issues, the above error can result if the CD being accessed is damaged.
User Action
To restore the lost data, check for an alternative source. If available and valid, use this source to regain the lost data and discard the corrupted file. However, if no other solution is available, use a third-party BKF Repair Tool to diagnose and repair corrupted Windows backup file. BKF Repair programs are user-friendly applications that facilitate easy and efficient BKF file repair using high end procedures, while keeping the original data intact.
