🔹 Kubernetes - Announcing Changed Block Tracking API support (alpha)

The blog post announces the alpha release of the Changed Block Tracking API, which enhances the Kubernetes storage ecosystem by allowing CSI storage drivers to efficiently identify changed blocks in PersistentVolume snapshots. This feature speeds up backup operations by focusing only on modified data instead of scanning entire volumes. The API supports block volumes but not file volumes and includes three key components: the CSI SnapshotMetadata Service API, a Kubernetes CustomResourceDefinition, and an External Snapshot Metadata Sidecar. Storage providers must implement CSI RPCs, have storage backend capabilities, and deploy external components to support this feature. Backup solutions must establish authentication, implement client-side streaming, and optimize workflows using the changed block metadata. The post also outlines how to get started with this feature, its benefits, and how to get involved in its development through the Kubernetes Storage Special Interest Group. 👉 Read more
