Instance-level backup of the rented appliance, taken by the host we rent the machine from. It is priced at what they charge us plus the declared rate, per machine. It is NOT the platform’s own backup module, which is included in the licence and costs nothing extra.
We are not selling this today. The figure it is computed from has to be current, and ours is not - ask us and a person will tell you what it costs rather than a page quoting you a stale number.
