You can backup an entire cluster at any time. Cluster information that is captured includes the Global Controller and worker node settings, site configurations, users and role information, persistent volumes, and related metadata. Dell Technologies recommends that you change the backup file location to an external backup location. You can also select a specific backup file and use that to perform a restore. Restoring from a backup restores the Global Controller and worker nodes, site configurations, users and role information, persistent volumes, and related metadata. Back up files are valid for up to 30 days. For details about backup and restore, see the Bare Metal Orchestrator Command Line Interface User's Guide.
