How to recover data when NTBackup cannot restore data from bkf file

NTBackup is a simple utility that is built in with Windows 2000, Windows XP and Windows Server 2003 Operating Systems to back up and restore data. Microsoft, the developers of Windows has replaced NT Backup with another utility named Windows 7 File Recovery (or Windows Backup and Restore Centre) in later version of Windows. And in Server Operating Systems starting from Windows Server 2008, a facility named Windows Server Backup has been introduced for backing up and restoring data.

When you need to backup data or needs to restore data from backup, you can open this tool through Accessories > System Tools from the Start Menu of the Windows. Alternately, you can run ntbackup.exe in the Run prompt or Command line.

NTBackup utility saves files to disks, tape drives and ZIP drives in BKF format and restores files from the backup when required. Sometimes, when you try to restore the data from the NTBackup, you may receive the message ‘The backup file contains unrecognized data and cannot be used.’ And you won’t be able to access the back up the files. It means that your backup files are corrupt. Then how can you restore your data?

Backup file corruption can happen due to many reasons such as: issues with ownership, mapping or permissions, and accidental system shut down at the time of backing up the data or accessing the data. It can happen due to the deletion of archive bit also. On Windows, when a file is created or modified, a file attribute named ‘archive bit’ is set. And when the file is backed up, the archive bit is cleared. Thus by looking at the status of the archive bit, one can say whether a file is backed up or not. Sometimes archive bit may get deleted due to some problems such as corruption, virus attack or some other error. In that case you won’t be able to restore backup files backed up by the NT Backup.graph

You cannot restore data from corrupt backup files using the NTBackup utility.  Even the System Restore utility of Microsoft Windows won’t restore backup files. So you will have to depend on third party software like Kernel Recovery for BKF for restoring the backup files.

Depending upon the depth of corruption, you can use either the Quick mode or Advanced mode of this tool to recover the backup files.
