Android Auto Backup Conflict Resolution -

-

android m introduced auto backup apps: https://developer.android.com/preview/backup/index.html

how service handle conflict resolution?

example: have 2 android devices linked same google play account, running same app; , app has different data on between 2 devices. when android backs data how google determine keep?

tl;dr: both kept

backup data app associated 1 specific device. if factory reset device henceforth considered new device.

what means if have 2 android devices on same google account both have duplicated backup sets, independent of each other. next time go through setup-wizard on new device , add google account, have option restore either of 2 devices.
