I've got a corrupt ntbackup file that won't open in ntbackup.
There are various utilities that a google search turns up that say they can repair the files. Do I need to use one or is there a simple way of using ntbackup to do this?
Update: This forum thread on tek-tips has some very useful information, like
As alternative you could try this commercial software for BKF recovery.
There is also an open source project on SourceForge: JMTF
If the backed up files within BKF are neither compressed nor encrypted then it is fairly easy - well not too hard - to extract single files manually by using grep, hexedit and dd.

Example (assumes using bash shell): extract Outlook.pst
Inspect offsets.txt, find offset that is followed by "NACL" "CSUM" and "STAN"
STAN means "Standard stream", the byte count is in 8 bytes (little endian) that begin 4 bytes after "STAN", so in this example
This will take some time if the file is large ... done!
