A set of C++ command-line tools (cdc_rsync and cdc_stream) for syncing and streaming files from Windows to Windows or Linux, using Content Defined Chunking (FastCDC) for efficient delta transfers. Originally built for Stadia game developers to rapidly sync large game builds to remote Linux instances.
Use cases
- sync large game builds from Windows to a remote Linux machine faster than rsync
- transfer only changed parts of big files over a slow connection
- stream files to a Linux instance over SSH without copying full archives
- replace scp for iterative development with many small files
- delta-sync directories between Windows machines
When to choose
- you need fast Windows-to-Linux file sync with delta transfers
- rsync/scp is too slow for your large, frequently changing builds
- you want fast compression and efficient handling of many small files
When to avoid
- you need a general-purpose cross-platform sync daemon with continuous monitoring
- your platforms are not Windows/Linux or macOS is the target
- you need GUI-based file synchronization
