What?, just what are you on about?
Our future subscription service offering uses your internet service in the exact same way as your hub currently fetches platform updates.
So unless you've explicitly denied internet access to your hub, there's nothing that needs to be done to your firewall.
The backups will also include an option to further encrypt the data, though the database is already encrypted.
This is not a core service, it's a subscription add on, if you don't like the current feature set you don't have to purchase it.
