Foxing: High-Fidelity Filesystem Replication
Summary
Foxing is an open-source project that implements a high-performance replication system for Linux filesystems using eBPF. The repository features two components, fxcp (a fast copy tool) and foxingd (an eBPF-powered replication daemon), with architecture details, performance benchmarks, and Quick Start guides. It emphasizes near real-time mirroring with strong consistency guarantees and a processing pipeline from kernel events to target filesystems.
