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

The blog post announces the alpha release of the Changed Block Tracking API, which enhances Kubernetes’ storage ecosystem. This feature enables more efficient backup operations by allowing CSI storage drivers to identify changed blocks in PersistentVolume snapshots. The API focuses on block-level changes, reducing the need to scan entire volumes during backups, and is currently supported only for block volumes, not file volumes. It aims to address challenges like long backup windows, high resource utilization, and increased storage costs. The implementation involves components such as the CSI SnapshotMetadata Service API, a Kubernetes CustomResourceDefinition, and an external snapshot metadata sidecar. Storage providers looking to integrate this feature must implement specific requirements, while backup solutions must handle authentication and optimize backup workflows. The blog suggests ways to get started with the feature, outlines future plans, and provides resources for further learning and community involvement. 👉 Read more
