We just had a big discussion on this in this very newsgroup, under the
subject `why idle backups'.  Whether a tape can be `verified' depends
on your definition of `verify' and how much time and effort you are
willing to expend.  If you can take the file system offline (either by
unmounting or by running single-user) you could write a program to
compare a dump to the actual contents of a file system.

I know of no such utility (though it would be useful, e.g., before
moving a lab like we did here a few years ago).
