I was going through the cloud back up.
In there it says that to use the Google provided Android Backup Service, i need to register my application which will give me Backup Service Key.
My question is how will the same application on different devices receive their specific data?

Example:- the application remembers choice of burger and orders it from the online store:

It backs up application data like choice of burgers, payment gateway etc.

Person A and Person B is using the same application on different devices and have different choice of burgers and gateways.

So when the data are retrieved during re-install how will Person A have his choices and Person B his?
Is it possible to do this?

    Users are identified by the primary Google Account on the phone:

    When an Android-powered device that uses Android Backup Service runs your application, the system verifies that your Backup Service Key is valid and Android Backup Service saves the user’s data to Google servers using the primary Google account on the device.

    See http://code.google.com/android/backup/index.html.
