In the Windows NT (Windows Server 2003, XP, and 2000) systems, you have got the option to use the NTBackup utility that helps you in creating backups in the form of BKF files. It is very handy when you lose your valuable data because of any which reason because you can then restore the data using the same tool itself. However, sometimes it may happen that the BKF files, too, get corrupt thereby making you to panic. In such cases, you should look for the updated backup of the lost data. If the backup is not updated then you should use a third-party BKF repair to repair BKF file.
Consider a scenario wherein you regularly backup your Windows data using the NTBackup utility in incremental mode. When day while you were adding some data in the already created BKF file, you were unable to do so. An error message is displayed, that is:
The backup file is unusable. You must erase it, or choose another file.”
After facing such error message, the only thing that you can do is to click the OK button to close the message box.
The root cause of this abnormal situation is that the BKF file has got corrupted and, thus, is not in a valid Windows 2000 backup file format.
When Windows 2000 opens a BKF file, it examines the file to ensure that the file is a proper BKF file. If the file is damaged or incomplete, then NTBackup is unable to add any further data or restore the backed up data from it.
There is no option in Windows systems to repair a corrupted BKF file. However, you can take some precautions to ensure that such slip-ups do not happen in the future. You should review the backup reports regularly and always check the Application Event logs if you have to perform unattended backup operations.
However, to repair BKF file you need to use a third-party BKF recovery software to restore the inaccessible data. Such BKF repair tools are extremely safe to use that help you in getting back the valuable data from various storage media.
