The setup is very simple, but maybe too simple? If I was to consider this for a company, I'd want to know how to make backups and what the available strategies are for some basic highly available setup (or at least for a disaster recovery). "Snapshot the whole virtual machine" might not be a very good answer (and might not be possible if running on bare metal). Nice to see "buy a license an off you go" to be back though!
