GitHub - kubernetes-csi/external-snapshotter: Sidecar container that watches Kubernetes Snapshot CRD objects and triggers CreateSnapshot/DeleteSnapshot against a CSI endpoint.

The Kubernetes implementation of the Container Storage Interface (CSI) has been promoted to GA in the Kubernetes v1.13 release. Support for CSI was introduced as alpha in Kubernetes v1.9 release, and promoted to beta in the Kubernetes v1.10 release. The GA milestone indicates that Kubernetes users may depend on the feature and its API without fear of backwards incompatible changes in future causing regressions. GA features are protected by the Kubernetes deprecation policy.

Volume group snapshots were introduced as an Alpha feature with the Kubernetes 1.27 release and moved to Beta in the Kubernetes 1.32 release. The recent release of Kubernetes v1.34 moved that support to a second beta. The support for volume group snapshots relies on a set of extension APIs for group snapshots. These APIs allow users to take crash consistent snapshots for a set of volumes. Behind the scenes, Kubernetes uses a label selector to group multiple PersistentVolumeClaims for snapshotting.

The support for volume group snapshots relies on a set of extension APIs for group snapshots. These APIs allow users to take crash consistent snapshots for a set of volumes. Behind the scenes, Kubernetes uses a label selector to group multiple PersistentVolumeClaims for snapshotting. A key aim is to allow you restore that set of snapshots to new volumes and recover your workload based on a crash consistent recovery point.

Volume group snapshots were introduced as an Alpha feature with the Kubernetes v1.27 release, moved to Beta in v1.32, and to a second Beta in v1.34. We are excited to announce that in the Kubernetes v1.36 release, support for volume group snapshots has reached General Availability (GA). The support for volume group snapshots relies on a set of extension APIs for group snapshots. These APIs allow users to take crash-consistent snapshots for a set of volumes.

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.
