Is there a way to read a BKF file from Windows XP using Windows 8? I tried installing the Windows 7 restore only pkg from the Microsoft web page (http://support.microsoft.com/kb/974674), but the update failed on my Windows 8 system with a certificate error message.

FWIW, I can still read my Sun backup tapes from 20 years ago. This XP file is 5 years old...

Download and extract nt5backup.cab or xp_files.rar, run NTBackup.exe, ignore errors about the Removable Storage service not running, open your BKF and restore your files:

Thanks. Links worked, but now I have a different problem. My backupfile is about 100G & restore failed when loading "backup file contains unrecognized data and cannot be used". This file was saved to tape via gtar (which had no trouble restoring it) & passed the MD5 checksum. Failed reading from NAS, so I copied to local drive & same error. Any thoughts? Thanks. –  KentH Jan 25 '13 at 15:59
    
Sorry, never used Windows' built-in backup, ever (never trusted it to get things right). –  Karan Jan 26 '13 at 21:16
    
Also remember to run ntbackup.exe as an administrator. Otherwise, depending on permissions of the original files and the destination directory, many of your files will fail to be restored. I learned this the hard way. –  Royce Williams Nov 12 '13 at 16:11

After less than successful attempts at having NTRestore read my old backup file, I found a project mtftar which transcodes a NTbackup file (bkf) into a standard tar file. Recovered 100K files no problem with tar.
