1 Introduction

This document describes procedures to perform disaster recovery for Oracle Communications Cloud Native Core Console (CNC Console) deployment. The operators can take database backup and restore them either on the same or a different cluster.

Prerequisites

Before you run any disaster recovery procedure, ensure that the following prerequisites are met:

• DBTier should be in healthy state and available on multiple sites along with CNC Console.
• On demand backup should be enabled on DBTier. Scheduled regular backups help to:
  • Restore stable version of the CNC Console configuration database.
  • Minimize significant loss of data due to upgrades or roll back failures.
  • Minimize loss of data due to system failure.
  • Minimize loss of data due to data corruption or deletion due to external input.
  • Migrate Console database information from one site to another.
• Custom values file used at the time of Console deployment is retained. If the custom_values.yaml file is not retained, then regenerate it manually. This task increases the overall disaster recovery time.
• Docker images used during the last installation or upgrade must be retained in the external data source.

  For the CNC Console database backup and restore prerequisites, see CNC Console Database Backup and Restore section.

Audience

The CNC Console Disaster Recovery Guide provides guidance to network administrators and professionals responsible for deployment and maintenance of CNC Console.
