FreeFileSync

FreeFileSync helps you manage your file backups through intelligent synchronization. It creates and maintains backup copies by first performing a detailed comparison between your original files and the backup location. The software then updates the backup by copying only the files that are new or have been modified, ensuring a complete and current copy without the wait of a full transfer. This efficient, difference-based approach, available for free on Windows, macOS, and Linux, makes it an essential tool for reliable and fast data protection.
