One of the things that can cause this is the image 
being manually 'de-compressed' without NBU *knowing* 
about it.

Example:

Images in the IMAGEDB are compressed every X number of 
days (default is 0 never to compress) as part of the 
global attributes.

An administrator or user with rights, decides to de-
compress one of the images in the IMAGEDB from the 
commands line

uncompress IMAGEID

They 'do' whatever they need to do with the file, but 
never compress it again.

NetBackup finds that this image has expired, and 
attempts to prune it from the DB, but it can't find it 
due to a *BAD HEADER*.  Which means that the file it 
expects to find IMAGEID.Z can't be found.

If this is indeed the problem, simply compressing those 
images in question will do the trick so the next time 
NBU attempts to prune the DB it will be successful.

This has been my experience anyway.

I hope this was helpful
