Perhaps use the 'find' command with the '-perm' argument to generate
lists of files that are and are not world readable, and pipe the
outputs to the backup program with the appropriate invocations? I'm not
a find guru, so I won't try to give the syntax, and I can't judge the
level of performance hit that doing it this way will engender.
