Do they really want to do this? If they do not trust that the file is being
backed up correctly by TSM, will they trust the fact TSM say's it has been,
even if it could verify the file?

The only way I can think of actually getting a byte by byte verificatiuon
that a file has been stored correctly by TSM is to do a restore of the file
and attempt to use it. If it works, the backup was fine.

Are they worried about things like copy serialisation? Are there files that
they think may not backup correctly for a particular reason?
