Velero Backup and Restore

1. Labelizing resources

All resources of componant to backup should be lablized. For example, regarding Grafana application, resources labelized with velero=grafana-backup.

kubectl -n monitoring label grafana.grafana.integreatly.org/grafana replicaset/grafana-deployment-XYZ pvc/grafana-pvc pv/pvc-XYZ serviceaccount/grafana-sa configmaps/grafana-ini  configmaps/grafana-plugins secrets/grafana-admin-credentials secrets/grafana-credentials services/grafana-service ingress/grafana-ingress servicemonitor/grafana pod/grafana-deployment-6598b4f597-p6ncb velero=grafana-backup

2. Backup

2.1 Create Backup manifest

Backup should be created through a manifest. In this example for Grafana application manifest file velero-backup-grafana.yaml (adapt content to the needs).

apiVersion: velero.io/v1
kind: Backup
metadata:
  name: backup-app-grafana
  namespace: infra
spec:
  includedNamespaces:
    - monitoring
  includedResources:
    - '*'
  volumeSnapshotLocations:
    - aws-default  
  labelSelector:
    matchLabels:
      velero: grafana-backup
  storageLocation: rs-velero-bucket-name
  snapshotVolumes: true
  ttl: 72h

2.2 Create Backup

Apply the manifest to create the backup itself.

kubectl -n infra apply -f velero-backup-grafana.yaml

2.3 Check Backup status

kubectl -n infra describe backup.velero backup-app-grafana

3. Delete resources

kubectl -n monitoring delete grafana.grafana.integreatly.org/grafana replicaset/grafana-deployment-XYZ pvc/grafana-pvc pv/pvc-XYZ serviceaccount/grafana-sa configmaps/grafana-ini  configmaps/grafana-plugins secrets/grafana-admin-credentials secrets/grafana-credentials services/grafana-service ingress/grafana-ingress servicemonitor/grafana pod/grafana-deployment-6598b4f597-p6ncb velero=grafana-backup

  namespace: infra
spec:
  backupName: backup-app-grafana
