Note Keep the following things handy during disaster recovery, depending on what is affected in your cluster. You must use the disaster recovery capability in any of the following scenarios: If Kyvos Manager, BI Server, or Query Engine nodes are affected. If only the Kyvos Manager nodes are affected. If Kyvos Manager and all Kyvos nodes (BI Servers, Query Engines, Web Portal, and Postgres Server) are affected.
If only the BI Server or Query Engine nodes are affected, then add a node for that service, and the cluster can be restored. You will not need to use disaster recovery capability for this case. If you enable TLS for Kyvos Manager and Kyvos application, the TLS option is not applicable during the Disaster Recovery restoration. After successful restoration, the TLS-related certificates are restored, and you can continue with the TLS option.
