If WhatsApp doesn’t detect a backup, it might be because:

• You aren't logged into the same Google account.
• You aren't using the same phone number that was used to create the backup.
• Your SD card or chat history is corrupted.
• A backup file doesn't exist on the Google Drive account or locally on your phone.

If you’re having issues creating a Google drive backup, verify the following:

• If you're attempting to back up using cellular data, you have data for both WhatsApp and Google Play services. Contact your provider if you're unsure.
• Attempt to back up on a different network. Try connecting to Wi-Fi if you're unable to back up using mobile data.
