    Former SyncToy user converted to FFS. Researched a lot of alternatives, found FFS came closest to what I needed. Completely dropped SyncToy now. Happily using FFS for several months.

    Rsync implementations on Windows are very slow when performing a first-time backup; two days or more in unacceptable for a task which SyncToy can perform in a few hours.

    Best alternative IMO, functionality wise. You can setup profile to sync between 2 folders, you can preview what file to be synced, can exclude files.

    A graphical interface for the Rsync engine that will synchronise files between two computers either locally or over the internet. The beauty of Rsync is that it only transfers the exact part of a file that has changed (differential synchronisation), saving bandwidth and time.
