Note that web2py comes with mercurial ("hg") pre-installed and accessible 
from the admin app.  Mercurial is pretty simple to use, and web2py wraps 
that for you so you don't have to much more than provide a description of 
your changeset and press a button.  It's already installed in the current 
versions (my experience only goes back to 2.5.1).

Mercurial is also a very capable VCS, so you can be sophisticated in your 
use of it.  I am somewhat in-between ... what you  might call an "everyday 
power user", using simple branching and tagging, and not yet into rebasing.

I'd recommend that you have a backup repository (which is simple to do) on 
another machine.  But just doing an xcopy/rsynch of your web2py directory 
will provide one copy, and you already do backup your web2py directory
