If you want to keep track of various version of a file, you need a
revision control system (and then backup the repository), such as
(<start holy war>): mercurial, cvs, rcs, svn, git, ...

more than one backup on the same media without doubling the actual used
size. But this starts requesting a bit of discipline.
