Taking App data backup from Windows Phone

My Windows Phone app开发者_如何学C doesn't have a service hosted but I would like to give the user an option to download/backup all the information(Just say note taking app) to another device or PC. How can we do that? Email attachment is an option but is there any other way?

Realistically you need to be looking at creating your own service/server for this if you want to do it now. DropBox (or similar) may be an option but it requires the users to already have an account.

Or wait until the Live SDK is available for the phone. (Or apply for the beta)
