As of macOS 10.5 and later, there is a special -E or --extended-attributes switch which allows retaining much of the HFS+ file metadata when syncing between two machines supporting this feature. This is achieved by transmitting the Resource Fork along with the Data Fork.zsync is an rsync-like tool optimized for many downloads per file version. zsync is used by Linux distributions such as Ubuntu for distributing fast changing beta ISO image files. zsync uses the HTTP protocol and .zsync files with pre-calculated rolling hash to minimize server load yet permit diff transfer for network optimization.zsync web siteRclone''' is an open-source tool inspired by rsync that focuses on cloud and other high latency storage. It supports more than 50 different providers and provides an rsync-like interface for cloud storage. However, Rclone does not support rolling checksums for partial file syncing (binary diffs) because cloud storage providers do not usually offer the feature and Rclone avoids storing additional metadata.
