Volume Backups and Restores

Manage volume backups and restores for cluster deployments.

Backups​

volsync automates scheduled volume backups to cloud storage. Apps can include the ReplicationSource resource to enable this functionality.

Manual backups

See volsync documentation for ad-hoc backup triggers.

Restores​

Use the homelab-helper project to perform volume restores by annotating the PersistentVolumeClaim:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    pvc-restore.homelab-helper.benfiola.com/backup: ""
  name: sample
  namespace: sample
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: default

The annotation value controls the restore source:

  • Empty string ("") - restore from the latest snapshot
  • Number - restore from N snapshots ago (e.g., 3 restores from three snapshots ago)
  • RFC3339 timestring - restore from a snapshot at the specified time
