I'm looking for redundant DNS, so I have two servers set up in ISPConfig: server A that has all the hosting clients' data and server B that has my site's data on it. Server A acts as a DNS (primary), database, e-mail and web server and server B is only configured in ISPConfig for DNS. What I'm wondering is if I set server B to be a mirror of server A in the Server Services feature, will that JUST be for DNS? Server B only has DNS checked in ISPConfig, and Server A has everything checked. I just don't want all of the other data on server A copied over as well (just DNS records).
