During my testing and breaking things of course I have been in a situation where some components and applications were not working properly. Now obviously the requirements for a homelab are less stringent and demanding compared to a Production environment. When making this considerations I was wondering if there was a way to easily replicate DNS data to a different system. And homelabs these days are not that different. Production environments should always have a protection plan which provides a line of defence not just against data loss but also availability for the data. Without a name resolver some applications might not even be fully working. Why are they so important? More and more apps, hosts and devices on the network communicate with each other relying on name services and of course just the вЂњstandard DNSвЂќ is key to the large majority of applications. Now to the question as to why would I need a second DNS server? Well there are plenty of reasons and in particular all focused on the availability of the data in this case DNS records data. And there are plenty of them divided by categories. Simply put there are built-in and downloadable Apps that further extend the functionalities of these NAS boxes. Configuring Synology DNS as a secondary Server is a simple operation.
