> If the Ambari server host is lost, there should be capability to provision a new Ambari server that can be brought up with most of the existing state. We can assume that the Database would be external and retains its state.
> This requires:
> Backup feature to periodically backup Ambari non-DB state: keystores, certificates, Ambari server state, agents states
> Restore feature to start an Ambari server from a back up. Also, re-point agents to the new Ambari server.
