Restore

Follow this guide to restore an Elemental configuration from a backup with Rancher.

Prepare rancher-backup operator and backup files for restoring

Go to official Rancher documentation and make sure that rancher-backup operator is installed and has access to backup files.

You first have to follow this documentation to do a backup of Elemental resources.

Restore the Elemental configuration with rancher-backup operator

Create a restore object (adapted to your needs) to restore the backup tarball.

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: elemental-restore
spec:
  backupFilename: rancher-backup-430169aa-edde-4a61-85e8-858f625a755b-2022-10-17T05-15-00Z.tar.gz

Apply manifest on Kubernetes.

kubectl apply -f elemental-restore.yaml

Check logs from rancher-backup operator.

kubectl logs -n cattle-resources-system -l app.kubernetes.io/name=rancher-backup -f

Verify if backup file was restore successfully.
