Backing up Windows Primary DNS server to restore back the state in case replication went wrong

Hi All,

Is there a fast and easy way to backup our primary DNS server on Windows Server 2003 ?
I'm about to do DNS replication from one site to another and just precaution what should I backup in case the replication goes wrong and how to restore it.

Thanks.

yes it is AD integrated.
Then it is automatically backed up with AD. The System State backup pulls Active Directory when run on a Domain controller. If there is a problem, you will just need to authoritatively restore the zone entry in the backup.

"authoritatively restore the zone entry" --> this sounds scary (-_-)"
An authoritative restore marks a specific set of restored data for replication to all domain controllers in the forest after the AD services start up on the server. If you only have one DC, you don't have to do an Authoritative Restore. If you have lots of Domain Controllers, the only way to make sure all of the DCs get the restored data (without restoring it on each domain controller) is to do an authoritative restore.

ahh. IC

the scenario is like this

Site A (HQ): ServerA - Primary DC and DNS and DHCP

Site B (Branch): ServerB - DNS and DHCP for site B only

so in order to do this then i should backup Site A only since the replication that I want is from site A into site B, not the other way around.

ah.. IC, at the moment I have no plan to DCPROMO site B windows server box.

So does the DNS replication can still be going or not possible without making the AD integrated zone ?
