If you make it a practice to manually back up that folder, I suppose that that's easy, but Time Machine makes it effortless. I have, once or twice, used TM to revert to a previous version of a file and it's quite painless. I also maintain a SuperDuper clone but TM is worth the trouble to set up. After that, you don't have to do anything except let it run.
