Is it possible to setup a backup DNS service node in PPA?
While planing the new PPA system setup, you wish to have a backup DNS service node in case of a system failover.
Yes, it is possible to setup a backup DNS service node to be used in case of a system failover. In order to implement that, you would need to add a new slave DNS service node. Add the node to PPA by running the wizard:
Infrastructure > Service Nodes > Add New Node in the Administration Panel
During the node registration, specify the DNS Server role (or one of the combined roles which include the DNS service).
Once you add the node, it appears in the list of registered PPA name servers, which is available at:
Services > DNS Zones > DNS tab > Nameservers
Set this node as a slave name server in the DNS resource type properties located at the
Products > Resources > DNS > Activation Parameters tab
In addition, you can set the SOA record template parameters: refresh and retry intervals, expiration period, and minimum TTL. The template settings are applied to the SOA record of all zones but can be overridden for a specific zone.
