What is Backup DNS and How to Restore DNS Zones?

Backup DNS comes into play, serving as a critical safeguard. Managing your DNS (Domain Name System) settings with precision is more important than ever. DNS is often described as the phonebook of the internet, translating human-friendly domain names into IP addresses that computers use to identify each other on the network. Any disruption in DNS can lead to websites becoming inaccessible, potentially causing significant business impacts. In this article, we’ll explore what this service is, its importance, and how you can restore DNS zones from backups.

What is Backup DNS?

Backup DNS is a service that makes daily copies of all your DNS zones and settings. These backups store comprehensive records of your DNS configurations, usually for a fixed duration—most commonly 30 days. This includes all types of DNS records such as A, MX, TXT, and CNAME records, among others. By maintaining these daily snapshots, Backup DNS ensures that you have a reliable fallback option in case your current DNS configuration encounters issues or needs to be reverted to a previous state due to administrative changes or DNS attacks.
