Absolutely. There was a program called cktar on the net a few months ago.
It gets the names from the tar device looks in the directory for a
matching name, and then does a byte by byte compare.
It also is supposed to report for problems matching UID's, GID's, and time
of modification difference, and will give a position in the file where the
comparison failed. I don't know if those work because I run the check
after backing up so none of those have changed.
