Our verdict
FreeFileSync is the tool we suggest for making backups to an external drive: compare two folders, review the differences, then copy only what changed. Mirror, two-way and update modes cover most backup routines, and RealTimeSync can run jobs automatically. The project relies on ads and donations; a paid Donation Edition adds extras such as parallel copying and a portable version.
