Scheduled Management Backups

Backups should be run on a schedule consistent with the policy requirements of the environment. For example a production environment might be set for "daily" backups, while a testing environment is set for "weekly".

Create a Management Backup

Periodic backups are handled by a ManagementBackup object, which uses a Cron expression for its .spec.schedule field. If the .spec.schedule field is not set, a backup on demand will be created instead.

Optionally, set the name of the .spec.backup.storageLocation of the BackupStorageLocation object. The default location is the BackupStorageLocation object with .spec.default set to true.

For example, you can create a ManagementBackup object that backs up to the storage object created in the preparation step every 6 hours (ref: Kubernetes CronJob schedule syntax, "Vixie cron" step values). Create a YAML file called scheduled-backup.yaml:

apiVersion: k0rdent.mirantis.com/v1alpha1
kind: ManagementBackup
metadata:
  name: kcm
spec:
  schedule: "0 */6 * * *"
  storageLocation: aws-s3
EOF

Start the scheduled backup process by applying the YAML to the cluster:

kubectl apply -f scheduled-backup.yaml

Confirm the backup creation was successful by navigating to the appropriate storage console UI or from the command line:

kubectl get managementbackup

The managementbackup should show as Completed:

NAME              LASTBACKUPSTATUS   NEXTBACKUP   AGE
example-backup    Completed                       8m
