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.

Where your phone data is stored

Your backups are uploaded to Google and encrypted with your Google Account password. For some data, your device's screen lock PIN, pattern or password is also used for encryption.

How your data is protected

Your data is encrypted to help keep it safe and secure.

All data, including photos and videos, messages and more, are encrypted as they move between your device, Google services and our data centres.
Some data is further encrypted with your device's screen lock. Photos and videos in Google Photos and MMS media received from your operator aren't encrypted by your device's screen lock.

Tip: To hide sensitive photos and videos with your screen lock, you can save them to a special folder in the Google Photos app. Learn how to hide your sensitive photos and videos.

Automatically back up your phone

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 device to automatically back up your files.

Open your device's Settings app.
Select Google Backup.
Tips:
- If this is your first time, turn on Backup your device with Google One and follow the on-screen instructions.
- Select the data that you want to back up: Photos and videos, Device data or both.

Your photos and videos are already available in Google Photos. But you can restore the rest of the data that 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.

How backup handles your data

Important: The data that backup collects is encrypted in transit.

Backup sends your data to Google’s backup servers and helps you to transfer data between devices. Backup collects certain information to perform services on your device. Some of this functionality uses Google Play services. For example, backup collects:

Messages, contacts, app settings and preferences are collected as part of your personal backup.
Personal identifiers are collected to ensure that your backups are associated with you and your account.
Crash logs and diagnostics are collected for analytics and troubleshooting purposes.

Turn backup off

To disable your backup, go to Settings System Backup Backup by Google One.
To delete your backup, you can also use the Drive app on Android.
