About

Fast rsync-like tool for incrementally copying files. Runs natively on both Windows and Linux and uses network for communication, to maximise speed when syncing between Windows and WSL filesystems.

Features

• Local or remote targets (including remote to remote)
• Fast, especially when nothing has changed
• Runs natively on Windows and Linux. Much faster than using WSL with /mnt/ or \\wsl$\
• No setup needed on remote targets
• Preserves symlinks
• Filters
• Replay frequently used syncs
• Sync multiple folders in one command
• Dry run
• Progress bar and statistics

Installation

1. Install the rust build tools: https://www.rust-lang.org/tools/install
2. Install build tools for cross-compiling (see below)
3. Run cargo install rjrssync

This will download the latest release of the source code from crates.io, build and then install rjrssync.

As part of the build, rjrssync is also cross-compiled for several other platforms and these are embedded into the final binary. You may need to set up your build environment for this to work, for example adding some additional targets to rustup.

Example (Linux)

sudo apt install mingw-w64 rustup target add x86_64-pc-windows-gnu rustup target add x86_64-unknown-linux-musl rustup target add aarch64-unknown-linux-musl

Example (Windows)

rustup target add x86_64-unknown-linux-musl rustup target add aarch64-unknown-linux-musl

Usage

A quick example:

rjrssync local-folder/ user@hostname:/remote/folder

rjrssync uses ssh to estabilish an initial connection to the remote host but then switches to its own protocol to maximize performance. The first time that a remote host is used, rjrssync will deploy a pre-built binary to the remote host, which will be launched whenever rjrssync connects to that host. You will be prompted before this deployment happens.

See rjrssync --help for more.
