I'm not really into letting Google own everything of mine, but my understanding is that if I was, then I could enable Google Drive and some other settings, and then everything (?) would end up on a Google server somewhere, for automatic restore.
Dunno for sure, though. Anyone out there tried it?
I'm 99.9% sure that isn't the case Mark.
I guess I want to know from you two what it is you want to back up. I don't know what you think is getting backed up, and I don't think it's as much as you think it is!

I would be interested in hearing how Android users here move their data/settings for all their many from one device to another (and whether it involves messing about with root access). But only if they are Nexus 7 owners, obviously.
My apologies, for I am not a Nexus 7 owner, just someone who wants to be. That said, I do have two Android devices and have had many in the past. There is no "moving" anything, because from day one the OS has been a cloud-connected one. The whole idea is that when you log into a new device it all just comes down from the internet.
