    I've decided to get a cPanel VPS in addition to my dedicated server to provide some failover redundancy for DNS and to also back up existing accounts between the two systems. I want to use the VPS as a secondary DNS. Is it better to do a trust relationship between the servers or to do DNS clustering? I'm getting a bit confused by the terminology. I'm used to setting up primary and secondary DNS services by hand.

    Go on, have a guess
    I'd suggest using a DNS cluster. It removes any manual involvment and means that you can maintain the DNS zone files on either server. You effectively have two master DNS nameservers that sync with each other.

    Thanks - I've tried it and it works very well indeed.

    Name Servers?

    How would the name servers work out?

    I mean lets say you have one main domain that you wanted to cluster on the two servers. Would the original TWO name servers and their IPs be enough? Or would you need FOUR name servers with 2 IPs of each server?

    Thanks

    You would use one IP from the first server for your ns1 and another IP from the second server as your ns2. No need waisting four IPs for something that only needs two.
