We currently have primary and secondary DNS servers on our corporate network. They are setup in a master/slave type setup, where the slave gets its DNS information from the master.
I'm trying to figure out what the real advantage is for the master/slave setup instead of just setting up an automated rsync between the two to keep the DNS settings matched.
Can anyone shed some light on this? Or is it just a preferential thing? If that is the case, it seems like the rsync setup would be much easier to setup, maintain and understand.
