If you use Ntbackup.exe to back up data to a new tape while you are logged on with a user account that is a member of the Backup Operators group and the Users group, the tape cannot be restored. When you try to restore the tape, you receive the following error message:
This set cannot be catalogued because the media containing the set data is missing.
By default, members of the Backup Operators group do not have Control permissions for the library object in Windows 2000. Ntbackup.exe requires this permission. If the Backup Operators group does not have Control permissions and if a member of the Backup Operators group performs a backup operation, the backup media is incomplete.
To work around this issue, assign Control permissions to the Backup Operators group. To do so, follow these steps:
Right-click My Computer, and then click Manage.
In the left pane, expand Storage, and then expand Removable Storage.
Right-click the backup device that you want to use, and then click Properties.
Click the Security tab.
In the Name list, click Backup Operators.
In the Permissions list, click to select the Allow check box that is next to Control.
