Google One isn’t syncing my phone backup, how can I fix it?

Here’s how to get Google One backups working correctly:

Make sure your Android has a stable internet link, preferably Wi-Fi, and make sure that auto-sync and backup are turned on in Settings > Google Backup. Also, make sure that the Google One app is up to date and using enough space.

If backups still don't work, go to Settings > Apps and clear the cache and data for Google Play Services, Google One, and the Google app.

Then, restart your device and try a manual backup in Settings > Google > Backup > Back up now.

Also, make sure that your phone's date and time are set to automatic and that any battery-saving modes are turned off.

If you need to, remove and re-add your Google account in Settings > Accounts to update your sync details.

Start a new backup and wait up to 24 hours after making these changes. Google One backups can take that long, especially after setup or big changes.

Do you have another way to solve it? We'd love to hear from you in the comments.
