Data Protection

Data is protected on two levels outside Kubernetes. A logical volume is backed up to S3-compatible object storage as a chain of snapshots, and its snapshots are replicated to a second cluster, from which a failover can be served. The control-plane database itself is backed up periodically as well.

Topic	Purpose
Backup and Recovery	Backing up a volume to S3-compatible object storage, and restoring it.
Asynchronous Replication	Replicating snapshots to a second cluster for a failover.
Control-Plane Database Backup	Backing up and restoring the control plane's FoundationDB metadata.
