How to back up or restore WhatsApp data
WhatsApp chats can be backed up using Google Drive and restored to a new Android device. You can back up the messages as well as the media (photos, videos) that you have sent and received.
To back up successfully, you will need to ensure the following are in place:
Please note: You can only back up data between devices if they are using the same Operating System. If you delete your account through the WhatsApp settings, it will also remove your backup on Google Drive.
Restore your WhatsApp messages and media from Google Drive when you reinstall WhatsApp.
Please note: WhatsApp only allows the option to back up and restore for devices with the same Operating System. This is a function of the WhatsApp application.
Please note: If you don’t restore now, you won’t be able to restore later.
