Is it possible to do a complete image backup of an Android device via USB connected to a Windows PC without the Android device being rooted? I recently purchased a Nexus 7 tablet from Google and I also have a Samsung Skyrocket from AT&amp;T. Neither of the devices is rooted. I'm not too enthusiastic yet about rooting either of them, especially since it voids warranties and severely limits support options. Is there a way to obtain a complete image backup of either (or both) of these devices via the USB port on my Windows computer? If so, how? Thank you!
Most articles I have encountered where people wish to undertake a complete image backup of their device requires root. However I have come across an article written in How-To Geek entitled "How To Create a Full Android Phone or Tablet Backup Without Rooting or Unlocking Your Device".

The Article will take you throught the steps of :


Installing the Android SDK
Device Setup
Testing ADB
Backing up your device
Restoring a Backup

The article concludes by saying the complexity of using the Android SDK to create and restore backups is a bit much for the average user.
