Invalid Data Streams May Corrupt BKF File

NTBackup is an in-built backup tool in Microsoft Windows NT based operating systems. It is used to backup all your critical business and personal data. The data backed up by NTBackup tool is stored in the form of Microsoft BacKup File (BKF) file. To restore data from BKF file, you need to use NTBackup tool. Sometimes when you try to restore data using NTBackup tool, the restoration process may fail and the BKF file can become unusable. This problem occurs due to BKF corruption and you need to opt for BKF Recovery tools to reclaim your vital data.

When you attempt to restore your precious data from the BKF file using NTBackup tool, you might encounter the below mentioned error message:

"Unable to Restore"

With the occurrence of this error message, the NTBackup utility stops working and the restoration process gets terminated. This behavior of NTBackup tool makes the data backup unusable and causes critical data loss. At this point of time, you need to figure out the cause of this issue and repair bkf File.

Source of this problem

You may encounter this problem when NTBackup utility finds any unknown data stream in the BKF file. The unknown data stream of BKF file may be caused by third party BKF file that stores the data streams with the Stream IDs, which are not known by the NTBackup tool.
In place of neglecting the invalid data stream and carrying on with the restoration process, NTBackup becomes incapable of restoring the data and displays the above error message.

Invalid data streams might damage the BKF file when you try to restore it again and again. After BKF file corruption, NTBackup utility could not recognize the file and thus the restore process fails.
