Backup DNS

I have a domain controller which is also a DNS server.
It has some zones which are AD integrated zones and some primaries and some secondaries.

I would like to use NTbackup to backup Active Directory, DNS ( AD Integrated zones, Primary zones, secondary zones).

I wonder if I need to backup just System states and this will incluse everything or I need to backup another folder.
I also want to know if system 32 part of System state.


The botom line is if the server crashes I will still be able to bring back the DOmain controller with AD and DNS working as they used to.

If you know about DHCP, I also want to know if backing up System State will include DHCP

Thanks

another thing I forgot to ask about DNS.

If I have in one DNS server(which is aloso a DC) primary and secondary zones. Would these replicate zones also replicate to the other DNS which is also a DC.
I know that AD Integrated zoen will replicate since it's stored in AD Database, but I amnot sure about primary or secondary zone.

The Active Directory integrated zones are stored in the Active Directory database, so will be included with a System State backup. Other DNS zones have their zone files in C:\WINDOWS\system32\dns, so will also be included in a System State backup. The DHCP database is also located in C:\WINDOWS\system32, so again, will be included in a System State backup.

Primary and Secondary zones do not automatically transfer to another DC; you'd need to initiate a Zone Transfer or make them AD-integrated.

Zone transfer is enabled to the servers that show up under the Name Servers Tab.
This will automatically transfer the zone to windows system 32/DNS folder on the other DNS. Correct?

If you have enabled a Zone Transfer, then the non-AD-integrated zones will be transferred, yes.
