Blog: Kubernetes 1.27: Introducing An API For Volume Group Snapshots

Volume group snapshot is introduced as an Alpha feature in Kubernetes v1.27. This feature introduces a Kubernetes API that allows users to take crash consistent snapshots for multiple volumes together. It uses a label selector to group multiple PersistentVolumeClaims for snapshotting. This new feature is only supported for CSI volume drivers.

Some storage systems provide the ability to create a crash consistent snapshot of multiple volumes. A group snapshot represents “copies” from multiple volumes that are taken at the same point-in-time. A group snapshot can be used either to rehydrate new volumes (pre-populated with the snapshot data) or to restore existing volumes to a previous state (represented by the snapshots).
