title: BackupAgent has one cloud backup per Device?
body: <p>I have one Google Account with many devices attached (look in settings of market website). When I backup my App with <code>BackupAgent</code> and wipe another device, the wiped device doesn't restore anything. If I save a text "Nexus S" on one device and "Nexus One" on another one, they restore "Nexus S" and "Nexus One".  </p>
  
  <p>It is the normal behavior? Can we use <code>BackupAgent</code> with an unique backup as iCloud allow?</p>
