Incremental File Synchronization Using Optimized rsync and zsync Techniques

The article proposes an incremental synchronization scheme for Meituan’s Rhino Cloud Disk that shifts rsync‑style signature and delta generation to the client, leverages zsync‑like HTTP range fetching, and discusses challenges such as block fragmentation, low locality in binary files, server‑side merge overhead, and future optimizations like variable‑size chunking and Rabin fingerprint‑based content‑defined chunking.
