Protecting Stateful Workloads With CSI Snapshot
summary
CSI adds a Kubernetes-native snapshot API with CRDs VolumeSnapshot and VolumeSnapshotContent, controller-side createSnapshot/createVolumeFromSnapshot RPCs, a snapshot class for dynamic provisioning, and a plug-in-generated snapshotID separate from the user-supplied name. Snapshots report a readyToUse flag (some drivers upload asynchronously), restores use a DataSource on PVC to clone from snapshot, controllers prevent deletion during restore, and demos show WordPress recovery and OpenSDS snapshots uploaded to S3. Feature status: alpha in K8s 1.12 with policy, topology and hooks planned.
