I have 2 servers both in different data centers. If I want to use Cloudberry to backup server 1 to server 2, what protocol would you recommend? Also is there some sort of WebGUI since both machines are running Ubuntu Server? I have an old licenses of Cloudberry backup Linux server from 2017 and was thinking of using it.
You'd need to connect both machines via VPN and map one of them as a local destination, but that's not really a configuration that we officially support, because of our focus on the cloud backups.
