Blog backup and statistics?

After writing my first blog post I accidently deleted parts of it! What happened was this:

I edited the blogpost, saved and published it, so far so good.

Just after saving it, i got an idea for a minor change, so I went back using the browser, to the editor windows, this was a mistake! I did not notice the text was the old text before i changed it in the first place. So when i published what i thought was a minor change, in fact the first major change was gone!

So after retyped the first major change to my posting, it came to my mind: how do i perform a backup of my blog here at blogger.com?

Also I would like to know if someone actually visits, maybe there is some stats similar to that of AWStats?
