Taking timely backups of your valuable data is a very safe and effective practice. It helps you in safeguarding your data against various data loss reasons. For such reasons, you have the NTBackup utility in the Windows NT (Server 2003, XP, and 2000) systems. It enables you to create backups in the form of BKF files that can be restored in case of any emergency. Having said that, sometimes these BKF files too can get corrupt because of various reasons such as virus infections, CRC errors, inappropriate backup operation, etc. In such situations, you should use a third-party BKF repair tool to repair BKF file.
Consider a scenario wherein you are using Windows 2000. You are a member of the Backup Operators group and the Users group. You have created a BKF file in a new tape. Now, when you try to restore the BKF file, you are unable to do so. An error message is displayed, that is:
“This set cannot be catalogued because the media containing the set data is missing.”
Cause:
The root cause of this erroneous situation is that the members of the Backup Operators group do not have the required Control permissions of the library objects. These permissions are required by the NTBackup tool to perform data restoration. When the group does not have the permissions and a member tries to use the NTBackup tool, the backup media is rendered as incomplete and the error is raised. The other reason for this message is that the BKF file is corrupt.
Resolution:
To resolve this issue, you should assign the Control permissions to the Backup Operators group. This can be done by performing the following steps:

- Select the Allow check box in the Permissions list.
- Click the OK button to save the settings. Now, try to restore the BKF file. It should work now.
However, if you are not able to resolve the issue even after the aforementioned steps that means that the BKF file is corrupt. In such cases, you should use a third-party BKF repair tool to restore the trapped data. Such read-only tools are able to perform complete BKF recovery using fast yet sophisticated scanning algorithms.
