Creating a backup of Cloudera Control Plane

You can back up the Kubernetes namespaces and resources on Cloudera Embedded Container Service (ECS) and OpenShift Container Platform (OCP) for the Control Plane on the Cloudera Data Services on premises > Cloudera Management Console >Backup Manager > Control Plane page. You can choose to back up the resources within the cluster or to an external location.

Ensure that the following prerequisites are complete:
  • You must have the PowerUser role.
  • For OCP, ensure that a VolumeSnapshotClass is installed with a CSI driver that matches the CSI driver for the storage class used.
  • Before you use an external location for backups, you must ensure that you have enough storage on your local system. This is because a local copy of persistent volume claim (PVC) is created temporarily which is later deleted after the backup event is complete. For example, if you are backing up 1 TB data, you require a minimum of 2 TB or more storage on your local system, where 1 TB is the original PVC and the copy requires another 1 TB.
When you create a backup of the Cloudera Control Plane, Data Recovery Service (DRS) initiates the backup event or job for the chosen backup entity, assigns an ID called backupCrn to the backup event, and creates a backup of the persistent volume claim (PVC) snapshots of the Cloudera Control Plane namespaces and the backup event's PVC. CRN or Customer Resource Number is the Cloudera-specific identifier provided for an event or job.

When you choose external backup, additional external backup events or jobs for the PVCs in the Cloudera Control namespaces are initiated to backup the data externally using Kopia.

  1. Go to the Cloudera Data Services on premises > Cloudera Management Console > Backup Manager > Control Plane page.
    The sample image shows the Backup and Restore Manager page.

  2. Click New Backup on the Backups tab.
    The sample image shows the New Backup option on the Backups tab.
    The Create Backup modal window appears.
  3. Enter the following details on the Create Backup modal window:
    1. Optional: Enter a unique Backup Name.
    2. Choose the Backup Entity that you want to back up.
    3. Back up the resources to an external location by performing one of the following actions:
      1. Toggle External Backup Enabled.
      2. Choose another external location if you do not want to use the default external location.
    4. Click Create.
    The sample image shows the Create Backup modal window where you enter a backup name, choose the backup entity, and click create to create a backup.
  4. DRS initiates the backup event and generates a backupCRN which is an automatically assigned ID for the backup event.
    The backupCRN appears in the CRN column on the Backups tab that you can click to view the backup event details.
    The sample image shows the backup CRN as CRN on the Backups tab in Backup and Restore Manager.
  5. Click the CRN to view the current status of the backup event on the Backup Details modal window.
    The sample image shows the backup CRN as CRN on the Backups tab in Backup and Restore Manager.
