You have purchased a Peace of Mind Website Backup. Good idea!
I will create that backup for you asap. If you have a Dropbox folder linked to me already it will be in there, if you do not have a Dropbox folder I will make you one and send you a request.
The backup compiled in a zip file is large. A small site is 27mb so it requires a Dropbox folder to transfer it to you. You can download the zip file from there and store it on your computer for safe keeping or create your own Dropbox account (free) and keep it there.
