AllSync

FoldersSynchronizer is a nifty and popular utility for macOS (Apple Silicon and Intel) 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 pairs of 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... FS can display a preview panel listing all the files FS is going to copy, replace and delete. FS can save a log file or send it to a custom email address, and it can sync and automatically quit the application… FoldersSynchronizer has been successfully tested on macOS 14 Sonoma. Previous versions for previous macOSs, for Intel and PPC are available too.
