title: Android BackupManager and multiple devices linked with the same account
body: <p>I always wonder how <a href="http://developer.android.com/guide/topics/data/backup.html" rel="nofollow">Android's <code>BackupManager</code></a> will act when the same <code>BackupManager</code> enabled App is installed on multiple devices (e.g. Smartphone and Tablet) linked to the same Google Account. <a href="https://groups.google.com/forum/#!topic/android-developers/7IJPB4u5x8c" rel="nofollow">It seems that I am not the only one,</a> but I couldn't find any specification about this.</p>
  
  <p><strong>What's your experience with this scenario? Are there any official resources that describe that case?</strong></p>
