FreeFileSync
Free open source file synchronization and backup for every platform

FreeFileSync is an open-source folder comparison and synchronization tool available for Windows, macOS, and Linux. It intelligently detects differences between source and target folders and transfers only the changed data, avoiding redundant full copies. The project is sustained through donations and ad revenue, with a Business edition available for commercial use.
FreeFileSync compares source and target folders to identify differences, then transfers only the minimum data needed to bring them into sync.
