How do I backup or download my zone files?
In this article it is assumed that you have already setup your dns zone using the portal. In addition you know your public IP address of the workstation you are currently using.
In the portal you will need to add your public IP address to the Allow Transfer list for your domain.
Once complete you can transfer your zone file and back it up using an application like named-xfer
named-xfer -z example.com -f example.com.txt ns1.dns-engine.com
named-xfer comes with most unix distributions, however on Windows you use the ISC standardÂ named-xferÂ tool.
