Back up or restore data on your Android device

You can back up content, data, and settings from your phone to your Google Account. You can restore your backed up information to the original phone or to some other Android phones. You can't use back up when you set up a personal device with a work profile or for work only, or when you set up a company-owned device.

Restoring data varies by phone and Android version. You can't restore a backup from a higher Android version onto a phone running a lower Android version.

Important: Some of these steps work only on Android 9 and up. Learn how to check your Android version.

Back up content

Turn on automatic backups

Important: To help protect your backed-up data, use a PIN, pattern, or password screen lock, instead of a swipe or Smart Lock.

You can set up your phone to automatically save backup copies of your data.

  1. On your Android phone, open the Google One app Google One.
  2. Scroll to "Back up your phone" and tap View Details.
  3. Choose the backup settings you want.
    • If you get advice to install an app, update an app, or change your settings, follow the on-screen steps. Then, to finish, go back to the Google One app.
    • You can back up copies of your files with cellular data. To reduce the amount of data you use, use Wi-Fi instead.
  4. If necessary, allow Backup by Google One to back up pictures and videos through Google Photos.
  5. Tap Turn on.

Your Google One backup can take up to 24 hours. When your data is saved, "On" will be below the data types you selected.

What gets backed up
Important: Not all apps can back up or restore all settings and data. To find out about an app, learn how to contact its developer.

If your backups are uploaded to Google, they're encrypted using your Google Account password. For some data, your phone's screen lock PIN, pattern, or password is also used for encryption.

If you back up to Google Drive, here's what's backed up:

  • Contacts
  • Google Calendar events and settings
  • SMS and MMS messages
  • Wi-Fi networks and passwords
  • Wallpapers
  • Gmail settings
  • Apps
  • Display settings (brightness and sleep)
  • Language and input settings
  • Date and time
  • Settings and data for apps not made by Google (varies by app)

Erase after backing up

After you back up, you can reset your phone by erasing everything on it. Learn how to reset your phone to factory settings.

Get your data onto a new phone

When you add your Google Account to a phone that's been set up, what you'd previously backed up for that Google Account gets put onto the phone.

To restore a backed-up account to a reset phone, follow the on-screen steps. For more help, see your manufacturer's support site.

Your photos and videos are already available in Google Photos. But you can restore the rest of the data you backed up while you set up your new phone for the first time or after a factory reset. At setup, to restore your data, follow the on-screen steps.

The process can take up to 24 hours.
