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

The blog post announces the alpha support for a Changed Block Tracking (CBT) API in Kubernetes. This feature allows CSI storage drivers to efficiently identify changed blocks in PersistentVolume snapshots, enhancing backup operations by focusing only on modified data. The API, currently applicable only to block volumes, is aimed at improving backup efficiency by reducing time, resource usage, and storage costs. Key components of the implementation include the CSI SnapshotMetadata Service API, a Kubernetes CustomResourceDefinition (CRD), and an external snapshot metadata sidecar. Storage providers must implement specific RPCs and ensure backend capabilities for block-level change tracking, while backup solutions need to handle authentication and develop streaming client-side code. The feature is expected to move to beta in future releases based on feedback and adoption. The blog encourages community involvement and provides resources for getting started with the feature. 👉 Read more
