How to back up content added via Upfront

Hi, I have added quite a bit of content to my site here
http://crochetwithwire.com/
and am wondering how I back up the pages that I have created using Upfront (the link in the top admin bar). I have checked the pages themselves in the backend of the site, and the information isn't there.

Sorry if this is a dumb question, but I am new to using Upfront :slight_smile:

Cheers
