What is Google Backup and how do I set it up?

Google Backup automatically saves your contacts, messages, app data, and settings to the cloud. Google Photos saves your pictures separately. Both turn on automatically when you set up your phone and are free to use.

Google Backup is Android's automatic cloud backup system. It runs in the background and saves your contacts, SMS messages, app data, device settings, and WiFi passwords to Google Drive. Google Photos backs up your photos and videos separately. When you get a new Android phone and sign in with your Google account, everything restores automatically.
