There is a problem with the solution's architecture. First of all, it requires double the resources on the virtual environment to set up one environment. You set up a cluster of virtual machines per site, so you are doubling the resources you need. While it wastes resources, it also provides a strategy to do high availability. It also lacks backward compatibility with some of the old vCenter servers. When you get an issue, they want you to upgrade up to the latest edition. However, when I have an old vCenter server, I should be able to use whatever version we have to do the replication. It also has a security vulnerability because it requires several ports to be open in the customer environment. These ports are open on the firewall. It also lacks a reporting mechanism to show a customer, the number of machines you've backed up and the difference. It's essential for a customer to know what is happening.
