🔹 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. This feature allows CSI storage drivers to efficiently identify changed blocks in PersistentVolume snapshots, leading to faster and more resource-efficient backup operations. Changed block tracking improves backup processes by tracking modifications at the block level, eliminating the need to scan entire volumes. This API is currently supported for block volumes but not for file volumes. The implementation includes three main components: the CSI SnapshotMetadata Service API, the SnapshotMetadataService API, and the External Snapshot Metadata Sidecar. Storage providers must implement specific requirements to support this feature, and backup solutions need to set up proper authentication and client-side code. The post also outlines the benefits of this feature, including reduced backup duration and resource consumption. The blog encourages interested users to try the feature and provides resources for learning more and contributing to the project. 👉 Read more
