Announcing Changed Block Tracking API support (alpha)

We're excited to announce the alpha support for a changed block tracking mechanism. This enhances the Kubernetes storage ecosystem by providing an efficient way for CSI storage drivers to identify changed blocks in PersistentVolume snapshots. With a driver that can use the feature, you could benefit from faster and more resource-efficient backup operations. If you're eager to try this feature, you can skip to the Getting Started section . What is changed block tracking? Changed block tracking enables storage systems to identify and track modifications at the block level between snapshots, eliminating the need to scan entire volumes during backup operations. The improvement is a change to the Container Storage Interface (CSI), and also to the storage support in Kubernetes itself. With the alpha feature enabled, your cluster can: Identify allocated blocks within a CSI volume snapshot Determine changed blocks between two snapshots of the same volume Streamline backup operations by focusin
