Backup and Restore
You don't normally have to worry about backups, they are automatically done after changes, either when the application closes, or after 15 minutes of inactivity.
Backups are also done when the DataStore is updated during the installation of a new version.
Backups are copied to a folder on OneDrive (you will be warned if OneDrive cannot be accessed), so there are copies of backups off your machine.
Automatic restores are performed when the application detects a problem opening the datastore. Manual restore is available, but should only be used after careful consideration.
