Sync and backs-up files, folders and disks.
FoldersSynchronizer is an nifty and popular utility for macOS which synchronizes and backs-up files, folders and disks. You can choose one or more pairs of files, folders or disks then FS will synchronize or backup those exactly.
FS lets you organize your sync and backup on several sessions you can save to a file for a later reuse. On each session you can apply special options like Timers, Multiple Folders, Filters, Exclude Items, Auto-Mount local and remote volumes, launch your own AppleScripts, set how to resolve conflicts, execute an incremental or an exact copy, include locked files.
