Your INI files are located in (My) DocumentsMy GamesHawkenHawkenGameConfig
Making a backup is as simple as copying them to another folder.
I would recommend against taking those backups and straight-across replacing the newer INI files, however, unless you're absolutely sure that nothing 
new has been added, and it's just been reset back to the defaults. Between now and Closed Beta Test 2, ,there could be important changes in the INI that'll cause the game to behave weird or unexpectedly if you were to revert to old INI files.
It does mean, however, that you can do side-by-side editing to easily change back your preferred values. Obviously, this's more annoying than going through the options menu, but some of us have tweaked the INIs to change settings (like turning off image grain or bloom) that currently aren't controllable in the UI.
