Back up with Large number of Resources

Applicable to Classic mode only

note

Backup and restore to NFS backup locations using KDMP applies to Classic mode only. NFS backup locations and KDMP are not supported in Federated mode.

Portworx Backup enables you to protect complex applications that consist of a large number of Kubernetes resources. You can append large numbers of resources or resource sets to your Namespaces and perform backup and restore operations without interruption.

The following topics provide instructions on how to create backups and restores of Namespaces that involve large numbers of resources or resource sets.

Back up Namespaces with a large number of resources

To create a backup of Namespaces with a large number of resources:

1. On the home page, click the cluster that holds the required Namespace.

2. From the cluster page, select the required Namespace(s) with a large number of resources.

3. All resources: this drop-down allows you to select:

• Required resources along with a search option to traverse the list with the resource name

• All the resources

Note that this drop-down only provides options to select resource types or resource groups, not individual resources.

• Vertical ellipsis > Select Resources: placed at the end of application row, this option allows you to select individual resources belonging to a resource group/type after selecting the resource groups through All Resources drop-down.

• Select Resources: this window provides options to select individual resources under every resource type.

4. After selecting the required resources, click Backup.

   Create Backup window does not display the resources included for the backup as the resource count is too large to display.

   

   Portworx Backup does not allow custom selection of resources from the vertical ellipsis when the resource count exceeds 1000. This limit applies to the total number of resources across all selected Namespaces in a single backup operation. By default, all resources in Namespaces are selected for the backup. In this scenario, the web console displays a notification message.

   

   Portworx Backup successfully creates a backup of the Namespace(s) with a large number of resources. Because of the large number of resources in the Namespace, the web console does not display the resource details in the Backup Details window after backup creation.

For uninterrupted backups of Namespaces that contain a large number of resources, you can add a few parameters to the ConfigMap in the kube-system Namespace and customize them to suit your environment. For more information on advanced settings related to these operations, see Large resource ConfigMap parameters.
