Excellent, efficient tool for manual backup and folder mirroring. No persistent services. Does what it promises and is updated frequently. Takes advantage of multicore now. A big thanks to the developers.

Thumbs up DG reviewed FreeFileSync:

Favourite tool I have used. Thanks so much. Makes keeping my USB stick and google drive in perfect sync.

Thumbs up tsreyb reviewed FreeFileSync:

Wow! FreeFileSync is the best backup tool I've ever used! I've bounced back and forth between many tools over the years, and this one is so much simpler (without sacrificing functionality) in so many ways. The backup process is quick and reliable.
