Backup /restore DNS ADIntegrated Zone.

Posted on 2009-04-21

I have a 2 DNS server zones with the same, but they are completely in different sites and different subnets.
I would like to backup the ADIntegrated zone from one DNS Server and restore to another DNS Server.
I know that it's not possible to backup ADIntegrated zone by itself without backing up the whole system state of the DNS Server. This will cause a problem when I try to restore it. It will overwrite the the existing system state of the secodn DNS server.

I wonder if there is a way to be more specific on what to back up from system state or when restoring the system state.

    i assume you purchased a new server and you want to copy over the dns zones? or are you truly looking for a backup model? the reason i ask is.. if you're just migrating servers, you can fire up the new server while keeping the old server online (to start). have the new server join the pre-existing domain. run dcpomo on the new server and make sure its setup as a dns server (dont make any changes to dns before or after). make sure AD sites and services replication is setup between the 2 dc's. wait for the new domain controller to auto replicate its ad dns zones to the new server. then transfer all the fsmo roles to the new server. run dcpromo on the old server to demote it. and then disconnect the old server from the network.

    both DNS servers have the same DNS zone, and already have records . I only want to add record fom one DNS to another. I don't want replication, this would overwrite the records in the other DNS.

    If I backup system State in one DNS server from one domain and restore it to the other DNS server in the other domain, it will mess up my AD structure since both domain have the same name and same name for DNS zone. I am not sure if I can restore the system state originated from a DNS Server which is also a DC to a DNS server which is not a DC. if it's possible, after restore then I will covert it to primary or secondary, change its name, then back it up again to a flash drive and take to another DNS server which is a DC and restore there as a primary zone, then convert it to ADIntegrated.
    that way I won't have to overwrite the system state.

    Most DNS problems are VERY easily troubleshot and identifiable if you can follow the steps a DNS query takes. I would like to share the step-by-step a DNS query takes from the origin to the destination. _____________________________________________…
