How to setup a backup NameServer?

[houguanghua]

Dave,
 
sorry for the delay reply.
 
These zones are not owned by ISP, such as: yahoo.com, facebook.com...
If such backup dns server is ready, ISP will talk to these WEB sites to keep synchronization with their authority NSs.
It's maybe a huge project.
 
Thanks,
Guanghua hou
