Yes (I hope so).

I don't use TeX for version control. I use a package that reads the  
string put into the file by the version control software (the  
$Id: .... $ string you must have seen before). The version control is  
done by cvs, completely outside of TeX. The side effect is that the  
date string within the file is updated, and available for LaTeX.

Version control is something different from frequent backups, as it  
also helps to synchronise different computers, and does more than  
simple backups can (branching, although I didn't use that).
