If you have connected your Pro Backup to your Google, you have the option to sync your files to Google Drive. To enable this go to Settings > Google Drive and switch on the toggle next to Sync files to Google Drive.
By default we do not enable this option as this can consume a lot of storage of your Google Drive. We therefore recommend verifying that you have enough storage available in your Google Drive before activating this option.
Note: Once you have enabled this option, it take up to a few days before all files are synced.
