Overview
parsync is a resumable sync tool for pulling files from SSH remotes or copying between local folders. It transfers many files in parallel, and can use optional block-delta sync. On Linux it can take an RDMA fast path for large whole-file copies when both hosts support it, and falls back to the normal transfer otherwise. It is written in Rust.
Key features
- Parallel file transfers over SSH
- Resume interrupted transfers
- Optional block-delta sync
- Linux RDMA fast path with automatic fallback
- Supports SSH config host aliases
Best for
Anyone moving large amounts of data over SSH who finds a single-stream rsync too slow. Windows metadata support is described as best-effort.
