Backup Google account data in the event you have to replace or reset your device so you can restore later.
INSTRUCTIONS & INFO
Swipe down from the Notification bar with two fingers, then select the Settings icon. Note: Android Backup Service backs up the following: Google Calendar settings, Wi-Fi networks & passwords, Home screen wallpapers, Gmail settings, Apps installed through Google Play (backed up on the Play Store app), Display settings (Brightness & Sleep) Language & Input settings, Date & Time, Third-party app settings & data (varies by app).
Scroll to and select Backup & reset.
Make sure that "Back up my data" and "Automatic restore" are ON.
If desired, select Backup account to ensure redundancy for backing up your data on the cloud.
Select the desired backup account option or select Add account to add a new backup account. When you add your Google account to a device, the data that you previously backed up for that Google account is restored to the device.
