Microsoft has provided “NTBackup Restore” utility in NT Family of Windows and later this utility is replaced with “Backup and Restore” in Windows 7 and “File History” in Windows 8. Though these utilities are capable of restoring data from Windows backup (BKF) files but there is no provision provided by Microsoft to restore data from corrupt backup files. So, if it is required to restore Windows XP, 2000, 2003 backup in Window 7 or 8, NTBackup Restore Utility for Windows 7, 8 & 10 needs to be downloaded from Microsoft website.

Whereas ‘’NTBackup Restore’ utility is the conventional way to generate backup as replica, ‘Backup and Restore’ or ‘File History’ creates image based backup which is faster and generated as snapshots of prevailing data. For personal reasons users still rely upon NTBackup Restore utility for creating backup. Keeping in mind user’s requirements, Microsoft offered NTBackup Restore utility for Windows 7, 8 and 10 which can be downloaded free of cost from Microsoft website and used to restore Windows XP backup files on Windows 7, 8 and 10.
