I use svn (Subversion) for version control, and I was glad to see  
that svn support exists for LaTeX (macros/latex/contrib/svn @ CTAN).  
Version control is so much better than "backup" for my current  
project, and even though the setup may require a bit of a learning  
curve, when you see the results, you really can't go back to doing  
things the "old" way.

Thanks Maarten, I wouldn't have looked for this without your suggestion.
