Creating a Backup CR

You back up Kubernetes images, internal images, and persistent volumes (PVs) by creating a Backup custom resource (CR).

Prerequisites

  • You must install the OpenShift API for Data Protection (OADP) Operator.

  • The DataProtectionApplication CR must be in a Ready state.

  • Backup location prerequisites:

    • You must have S3 object storage configured for Velero.

    • You must have a backup location configured in the DataProtectionApplication CR.

  • Snapshot location prerequisites:

    • Your cloud provider must have a native snapshot API or support Container Storage Interface (CSI) snapshots.

    • For CSI snapshots, you must create a VolumeSnapshotClass CR to register the CSI driver.

    • You must have a volume location configured in the DataProtectionApplication CR.

Procedure

  1. Retrieve the backupStorageLocations CRs by entering the following command:

    $ oc get backupStorageLocations -n openshift-adp
    Example output
    NAMESPACE       NAME              PHASE       LAST VALIDATED   AGE   DEFAULT
openshift-adp   velero-sample-1   Available   11s              31m

  2. Create a Backup CR, as in the following example:

    apiVersion: velero.io/v1
kind: Backup
metadata:
  name: <backup>
  labels:
    velero.io/storage-location: default
  namespace: openshift-adp
spec:
  hooks: {}
  includedNamespaces:
  - <namespace> (1)
  includedResources: [] (2)
  excludedResources: [] (3)
  storageLocation: <velero-sample-1> (4)
  ttl: 720h0m0s
  labelSelector: (5)
    matchLabels:
      app=<label_1>
      app=<label_2>
      app=<label_3>
  orLabelSelectors: (6)
  - matchLabels:
      app=<label_1>
      app=<label_2>
      app=<label_3>
    1 Specify an array of namespaces to back up.
    2 Optional: Specify an array of resources to include in the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified. If unspecified, all resources are included.
    3 Optional: Specify an array of resources to exclude from the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified.
    4 Specify the name of the backupStorageLocations CR.
    5 Map of {key,value} pairs of backup resources that have all of the specified labels.
    6 Map of {key,value} pairs of backup resources that have one or more of the specified labels.

  3. Verify that the status of the Backup CR is Completed:

    $ oc get backup -n openshift-adp <backup> -o jsonpath='{.status.phase}'
