grep -v will do an invert match, only returning the files that don't contain
the specified strings. You could then send that list to cp to make your
backups (make sure to use the -p flag to preserve permissions).
But unison is a tool that will do exactly what you want. If you put your list
of files in the ignore list in your preferences file, then unison will never
touch them. unison has a lot of other features too, so perhaps it is overkill
for your purposes.
