You can use Android Backup Service to back up data connected to one or more of your Google accounts. If you replace your device or erase its data, you can restore your data using the account(s) that you backed up.
Swipe down from the Notification bar with 2 fingers, then select the Settings icon.
Scroll to and select System.
Select Backup.
Ensure the Back up to Google Drive switch is on to ensure your data is backed up on the cloud.
ADD NEW BACKUP ACCOUNT: From the Backup screen, select Account then 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.
