Code strings related to the new "Backup and restore" feature suggest that users will be able to back up their Health Connect data Daily, weekly, or monthly. Google will also let users choose their preferred cloud storage provider for storing the backed-up data. Currently, it doesn't look like there will be an option to save the data locally on the device. A string in the source code says if you select a backup file from local storage, it will give you an invalid error and ask you to choose a cloud provider app from which you can restore the data.
