Back up or restore data on your Pixel phone

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

• Google Contacts
• Photos and videos

Note: To find out how long your phone backs up unlimited photos and videos at full original quality, see the tech specs or learn about upload sizes.

Up to 25 MB of data per app

• Apps and app data

• Device settings
• SMS text messages (not MMS)

This deletion includes app data, call history, device settings, and SMS messages. (Your backed-up photos and videos stay available in Google Photos. Your Google Contacts and Google Calendar still sync.)
