To enable recovery of Intigua 3.7 following a disaster scenario, you can deploy the Intigua server and database in two datacenters, with data replication. Upon failure, you can manually reconfigure the standby server as a single active server and redirect endpoint and administrative traffic to it.
One Intigua server is designated as active, and another, in a remote datacenter, as standby. The standby server's services are stopped. The active Intigua server uses a primary database in its same datacenter; a hot standby database is ready, in read-only mode, in the standby server's datacenter. Intigua-provided scripts set up the databases, replicate VAI content between the Intigua servers via Rsync, and replicate the database via asynchronous log shipping.
Endpoint connections to the primary server are by hostname rather than by IP address, and upon failure of the primary datacenter you activate the standby deployment and update DNS records to redirect endpoint and administrative traffic to it.
