Kubernetes Official Blog

2025-09-25

Kubernetes announces alpha support for a Changed Block Tracking API that lets CSI drivers report allocated and changed blocks between snapshots to enable faster, incremental backups for block volumes. The feature requires a SnapshotMetadataService CRD, an external-snapshot-metadata sidecar, and CSI SnapshotMetadata gRPC RPCs (GetMetadataAllocated and GetMetadataDelta) with streaming responses.

k8s: Kubernetes v1.34: Moving Volume Group Snapshots to v1beta2

Kubernetes v1.34 advances Volume Group Snapshots to v1beta2. The update adds a VolumeSnapshotInfo type and replaces VolumeSnapshotHandlePairList with VolumeSnapshotInfoList to fix restoreSize handling when CSI drivers do not implement ListSnapshots; objects are migrated from v1beta1 via a conversion webhook and the feature remains CSI-only with GA planned later.
