summary
CSI Snapshot API gives a single, provider-agnostic way to create and restore block or file-volume snapshots; Kubernetes exposes VolumeSnapshot/VolumeSnapshotContent/VolumeSnapshotClass CRDs, the controller issues CSI CreateSnapshot calls and stores the provider snapshot handle (demo uses AWS), and restores by creating a PVC that points to a snapshot with restore via PVC dataSource (works for the WordPress/MySQL demo). Ecosystem tooling builds on this, for example Velero CSI plugin, and incremental/delta snapshots are not supported yet.
