Backup and restore

MKE 4k supports backup and restoration of cluster data through the use of the Velero add-on. System backup is enabled by default. In addition, MKE 4k also supports etcd backups through the CLI.

Backup configuration

The backup section of the mke4.yaml configuration file renders as follows:

backup:
  enabled: true
  storage_provider:
    type: InCluster
    in_cluster_options:
      distributed: false

By default, MKE 4k supports backups that use the in-cluster storage provider, as shown in the type.InCluster field. In-cluster backups for MKE 4k are implemented using the MinIO add-on.

The distributed setting configures MinIO storage to run in distributed mode.

Create a backup and perform a restore

For information on how to create backups and perform restores for both storage provider types, refer to:

Existing limitations

  • MKE 4k does not currently support:

    • scheduled backups
    • backup to NFS storage
    • backup to local disks

  • Restoration Scope: Backups can only be restored to the same cluster where they were originally created. Restoring to a new set of nodes is not supported.
