rsync

Overview

rsync is the standard tool for efficient file synchronization. It only transfers changed parts of files (delta transfer), supports SSH, handles permissions, and works for backups, deployments, and directory mirroring.

Instructions

Step 1: Basic Usage

# Sync local directories
rsync -avz source/ destination/
# -a = archive (preserves permissions, timestamps, symlinks)
# -v = verbose
# -z = compress during transfer

# Sync to remote server
rsync -avz ./dist/ deploy@server:/var/www/myapp/
