Automation Suite on OpenShift installation guide

Backing up the cluster​

• You must back up only the primary cluster and external storage (SQL and Objectstore).
• It is not mandatory to take a backup of the secondary cluster. Instead, you can choose to take a backup of the secondary. However, you can still use the primary cluster to set up the secondary cluster.

Restoring the primary cluster​

• If the primary cluster goes down, you must use the backup to restore it.
• If configuration changes were made on the secondary cluster while the primary cluster was down, follow these steps to ensure the restored primary reflects the latest configuration:
  • Merge configurations from the primary and secondary clusters to create an updated input.json that includes all changes made on the secondary after the primary went down.
  • Apply any required updates to parameters that are specific to the primary cluster.
  • Restore the primary cluster using the merged input.json file.

Restoring the secondary cluster​

• If the secondary cluster's backup is unavailable, you can restore it from the primary cluster by taking the following steps:
  1. Generate the input.json from the primary cluster.
  2. Update the input.json with the specific value of the secondary cluster.
  3. Install the secondary cluster.
• If the backup for the secondary cluster is available, you can restore the secondary cluster from the backup.
