Backup app data without root and no micro USB port How can I backup an app's data (i.e. Angry Birds scores and achievements) on my Nexus 7, running Android 4.2.2? My tablet is not rooted and my micro USB port is damaged, disallowing me to connect to the computer. 

Any suggestions?
Probably Koush's Helium [which used to be Carbon previously] might be of help for you.


  Helium does NOT require root. 
  
  All Android users can use Helium to backup and sync Android
  applications.
  
  Helium lets you backup your apps and data to your SD card or cloud
  storage [Dropbox, Box, Google Drive].
  
  Android to Android app sync [With Helium, you can sync app data from
  your other Android devices -- even if they are not on the same
  network].


I am not sure if you have to connect your device to usb if you want to sync to cloud though. I have not used this feature as of yet.
