Restoring a Cloud Pak for Data online backup on the target cluster with NetApp Astra Control Center

Important: IBM Cloud Pak® for Data Version 4.8 will reach end of support (EOS) on 31 July, 2025. For more information, see the Discontinuance of service announcement for IBM Cloud Pak for Data Version 4.X.

Upgrade to IBM Software Hub Version 5.1 before IBM Cloud Pak for Data Version 4.8 reaches end of support. For more information, see Upgrading from IBM Cloud Pak for Data Version 4.8 to IBM Software Hub Version 5.1.

This information shows you how to restore a Cloud Pak for Data online backup to the target cluster with NetApp Astra Control Center.

Before you begin

If you previously tried to restore a backup unsuccessfully, delete all Cloud Pak for Data resources and projects (namespaces) before you attempt another restore. For details, see Restoring an online backup prerequisite tasks (NetApp Astra Control Center).

About this task

You cannot restore a backup to a different project of the Cloud Pak for Data instance.

Best practice: You can run the commands in this task exactly as written if you set up environment variables. For instructions, see Setting up installation environment variables.

Ensure that you source the environment variables before you run the commands in this task.

      ${OC_LOGIN}
      Remember: OC_LOGIN is an alias for the oc login command.
    2. Get the size of the elastic-master-backups PVC. 
      oc get pvc -n ${PROJECT_CPD_INST_OPERANDS} elasticsearch-master-backups -o yaml
      Under status.capacity.storage, note the size of the PVC.
    3. Edit the Common core services custom resource: 
      oc edit -n ${PROJECT_CPD_INST_OPERANDS} ccs ccs-cr
    4. Add the following line after spec, specifying the size noted in step 15b: 
      elasticsearch_backups_persistence_size: "<size>"
