Backup of apps and their settings I learned about Titanium Backup but I don't have a rooted device yet. 

I'd still like to backup all my installed apps and their settings - will the default Google backup:



What does this backup exactly?

Sorry if this has been answered before but I really couldn't find it on quick search. So maybe it won't hurt to have my post here.

I see that my best option is adb (Full Backup of non-rooted devices) though... but I still don't know what the default Google backup does then... and why it's not enough...
install Helium - App Sync and Backup &amp; APK Extractor (to backup your APK) from playstore it might help you but it will not save your settings
