backing up android device using adb [closed]

Answer 1

Execute on your computer

adb backup -apk -shared -all

This should hopefully create backup.ab with all of your apps, OS, and data. To restore, execute the following.

adb restore backup.ab

Answer 2

If you do not have root access on tablet1, certain data will not be accessible by adb, such as private application data, hence they will not be backed up. Try running 'adb root' first.
