Can’t complete or restore Google Account backup

Android
If your backup gets stuck while uploading or downloading, try:
  • Logging out and back into your Google Account.
  • Turning your Wi-Fi off and on, or using mobile data.
  • Force stopping or closing WhatsApp.
  • Reducing the size of your backup as your device might be running too low on space. Learn how here.
  • Checking that your device’s battery is fully charged or plugged into a power source.
  • Turning off your non-primary SIM if you’re using a dual SIM.
  • Check if the Google Play Services app needs to be updated. You can do this by opening your device Settings. Tap App and Notifications and then Google Play Services. Scroll to the bottom and tap Advanced > App Details. If your app displays Update, Google Play Services app is out of date.
If you receive any of the following error messages:
  • ‘This account already exists on your device’
  • 'Unable to access your account at this time'
  • 'Unable to back up messages'
  • Or your listed Google Account is grayed out when trying to add your Google Account to your WhatsApp
Follow these steps to resolve the issue:
  1. Go to your device settings.
  2. Tap Users and Accounts (or Accounts depending on your device).
  3. Select your Google Account.
  4. Tap Account Sync > Menu > Sync. Allow sync to finish so that your data is up-to-date.
  5. Go back to the previous screen and tap Remove Account.
  6. Open WhatsApp to add the previously removed account.
  7. Tap More options > Settings > Chats > Chat Backup > Account.
If these steps don’t solve the issue, check your permission settings for WhatsApp and Google Drive.
Note:
  • If your progress bar shows 100% complete and the notification doesn’t go away, there may still be background processes completing, including media upload or download. Please wait a few hours for the notification to go away.
  • Your Google Account only stores one backup per account. Each new backup overwrites the old one, so there’s no way to restore a previous Google Account backup.
  • If you restore a backup and chats are still missing, you most likely restored a backup file that didn't contain the missing chats.
