If you want to have versioning but don't want to do versioning yourself, then I recommend you take a look at File Hampster. FH is configured with the files/directories to be monitored; each time a monitored file is updated FH will preserve a copy of the previous version. It has configuration options to define how long old versions are kept for, to roll up multiple updates that occurred close together, let you save or discard or preserve individual updates, and so on. It doesn't give you all the capabilities of a fully-fledged change control system, but gets you a good way there at zero effort.
