"Disk Image" of non-rooted GS3

view story

http://forum.xda-developers.com – Hi everyone, I just got a new Verizon GS3, and would like to do the equivalent of creating a "disk image" of my phone. This feature has saved me numerous times on my PC, and I had used Sprite backup on my prior WM6.0 system to restore the phone from a ROM and then reload all my settings, folders, etc. However, the only full backup that I am aware of for the ICS system requires that I root my phone, and I am not willing to do that until my warranty expires. So my question: Is there any program or method to create the equivalent of a disk image of my Verizon GS3 (or otherwise (HowTos)
