Creating a Full Cluster Application Group for Kubernetes

You can create a full cluster application group that protects your entire Kubernetes cluster using namespace-centric protection. A full cluster application group automatically discovers and protects all namespaces, applications, PersistentVolumeClaims, and non-namespaced (cluster-scoped) resources/objects.

Go to the Add Application Group Dialog Box

1. From the Command Center navigation pane, go to Protect > Kubernetes.

   The Overview page appears.

2. Go to the Applications tab.

3. In the upper-right area of the page, click Add application group.

   The Add Application Group page of the configuration wizard appears.

Select the Cluster and Backup Plan

1. From the Cluster list, select the cluster to create the application group for.

2. Click Next.

   The Plan page of the configuration wizard appears.

3. Select the backup plan to back up the cluster and applications.

   If you don't already have a backup plan that you can use, to create one, click the add button and specify the details in the Create backup plan dialog box.

4. Click Next.

   The Add Application Group page of the configuration wizard appears.

5. In Application group name, enter a descriptive name for the application group.

Select the Resources to Back Up

1. Under Content, click Add, and then select Applications.

   The Add Kubernetes applications dialog box appears.

2. Select only the cluster.

3. Click Done.

Exclude the Applications or Resources from Backup

You can exclude Kubernetes applications or resources from an application group so that they are not backed up.

For more information, see Excluding Kubernetes Applications or Resources from an Application Group.

Create the Application Group

1. Click Submit.

   The application group properties page appears.

2. To run an on-demand backup of the application group, in the upper-right area of the page, click Backup.

   Important

   If you need to backup the applications or volumes in system namespaces (such as those that begin with kube- and openshift-), you can display the system namespaces in Commvault by using the bK8sShowSystemNamespaces entity setting.
