backup role server IP

Hello

Should the backup role dedicated server be available from the internet? Will be be ok if I will choose internal (RFC 1918) IP for it with NATed access to the global network?

An internal RFC1918 IP should be fine if it's reachable from all the servers in your cluster.

When you onboard the server to your cluster, you need to ensure the call home to the control panel is on the RFC1918 IP. Therefore you might want to override the public DNS for the control panel domain with an /etc/hosts entry on the backup server.
