Vitvm is a Git-like tool for versioning virtual machine state, including memory and running processes, enabling rapid snapshots in 72ms and forks in 100ms. It supports full machine checkpointing on Linux with KVM and a files-only mode for other systems, allowing users to inspect, diff, and resume any previous step without replaying.
DeltaSnap is a macOS application that transforms native APFS snapshots into a version control system for individual files and folders, allowing users to quickly recover deleted or modified files and browse file history. It leverages APFS's copy-on-write architecture for fast, space-efficient snapshots and integrates with AI agents to create checkpoints before risky operations.
Kubernetes Changed Block Tracking API moved from Alpha to Beta with the March 2026 v1.0.0 release of external-snapshot-metadata. The main change is the promotion of SnapshotMetadataService CRD from v1alpha1 to v1beta1, requiring users to re-apply CRD definitions and update manifests accordingly. The feature enables CSI drivers to track changed blocks in storage volumes, with focus now on wider adoption and operational feedback before GA.
