OADP features and plugins

OpenShift API for Data Protection (OADP) features provide options for backing up and restoring applications.

The default plugins enable Velero to integrate with certain cloud providers and to back up and restore OKD resources.

OADP features

OpenShift API for Data Protection (OADP) supports the following features:

Backup

You can back up all resources in your cluster or you can filter the resources by type, namespace, or label.

OADP backs up Kubernetes objects and internal images by saving them as an archive file on object storage. OADP backs up persistent volumes (PVs) by creating snapshots with the native cloud snapshot API or with the Container Storage Interface (CSI). For cloud providers that do not support snapshots, OADP backs up resources and PV data with Restic.

Restore

You can restore resources and PVs from a backup. You can restore all objects in a backup or filter the restored objects by namespace, PV, or label.

Schedule

You can schedule backups at specified intervals.

Hooks

You can use hooks to run commands in a container on a pod, for example, fsfreeze to freeze a file system. You can configure a hook to run before or after a backup or restore. Restore hooks can run in an init container or in the application container.

OADP plugins

The OpenShift API for Data Protection (OADP) provides default Velero plugins that are integrated with storage providers to support backup and snapshot operations. You can create custom plugins based on the Velero plugins.

OADP also provides plugins for OKD resource backups, OpenShift Virtualization resource backups, and Container Storage Interface (CSI) snapshots.

Cloud storage that supports CSI snapshots

  1. Mandatory.

  2. Virtual machine disks are backed up with CSI snapshots or Restic.

  3. The csi plugin uses the Velero CSI beta snapshot API.

About OADP Velero plugins

You can configure two types of plugins when you install Velero:

  • Default cloud provider plugins

  • Custom plugins

Both types of plugin are optional, but most users configure at least one cloud provider plugin.

Default Velero cloud provider plugins

You can install any of the following default Velero cloud provider plugins when you configure the oadp_v1alpha1_dpa.yaml file during deployment:

  • aws (Amazon Web Services)

  • gcp (Google Cloud Platform)

  • azure (Microsoft Azure)

  • openshift (OpenShift Velero plugin)

  • csi (Container Storage Interface)

  • kubevirt (KubeVirt)

You specify the desired default plugins in the oadp_v1alpha1_dpa.yaml file during deployment.

Example file

The following .yaml file installs the openshift, aws, azure, and gcp plugins:

  1. apiVersion: oadp.openshift.io/v1alpha1
  2. kind: DataProtectionApplication
  3. metadata:
  4. name: dpa-sample
  5. spec:
  6. configuration:
  7. velero:
  8. defaultPlugins:
  9. - openshift
  10. - aws
  11. - azure
  12. - gcp

Custom Velero plugins

You can install a custom Velero plugin by specifying the plugin image and name when you configure the oadp_v1alpha1_dpa.yaml file during deployment.

You specify the desired custom plugins in the oadp_v1alpha1_dpa.yaml file during deployment.

Example file

The following .yaml file installs the default openshift, azure, and gcp plugins and a custom plugin that has the name custom-plugin-example and the image quay.io/example-repo/custom-velero-plugin:

  1. apiVersion: oadp.openshift.io/v1alpha1
  2. kind: DataProtectionApplication
  3. metadata:
  4. name: dpa-sample
  5. spec:
  6. configuration:
  7. velero:
  8. defaultPlugins:
  9. - openshift
  10. - azure
  11. - gcp
  12. customPlugins:
  13. - name: custom-plugin-example
  14. image: quay.io/example-repo/custom-velero-plugin

OADP support for IBM Power and IBM Z

OpenShift API for Data Protection (OADP) is platform neutral. The information that follows relates only to IBM Power and to IBM Z.

OADP 1.1.0 was tested successfully against OKD 4.11 for both IBM Power and IBM Z. The sections that follow give testing and support information for OADP 1.1.0 in terms of backup locations for these systems.

OADP support for target backup locations using IBM Power

IBM Power running with OKD 4.11 and OpenShift API for Data Protection (OADP) 1.1.0 was tested successfully against an AWS S3 backup location target. Although the test involved only an AWS S3 target, Red Hat supports running IBM Power with OKD 4.11 and OADP 1.1.0 against all non-AWS S3 backup location targets as well.

OADP testing and support for target backup locations using IBM Z

IBM Z running with OKD 4.11 and OpenShift API for Data Protection (OADP) 1.1.0 was tested successfully against an AWS S3 backup location target. Although the test involved only an AWS S3 target, Red Hat supports running IBM Z with OKD 4.11 and OADP 1.1.0 against all non-AWS S3 backup location targets as well.
