Local Mac To SFTP & FTP Sync: Chronosync

In our ongoing series on syncing local Mac folders with SFTP To Go, we’ve explored a range of nifty FTP sync tools for Mac, file managers, and FTP clients, including FreeFileSync, GoodSync, Transmit 5, and Forklift. 

FreeFileSync offers an open-source manual option with somewhat convoluted automation options, while GoodSync excels in automation all on its own. Transmit 5 is great for quick manual FTP syncs (and SFTP Syncs), and Forklift brings user-friendly two-way sync features, albeit also manual.

This post is all about ChronoSync, known for its automation features, flexible scheduling, real-time SFTP or FTP sync, and advanced file archiving and restore features.

We’ll walk you through the setup and show you why ChronoSync is such a popular choice for sensitive file management and customizable SFTP and FTP synchronization between your local Mac and SFTP To Go.

ChronoSync won’t connect to the SFTP To Go server unless the app is open.  


If you’ve configured triggered or scheduled sync, ensure you set ChronoSync to open at login by CTRL clicking the dock icon and selecting “Open at Login”. Missed scheduled tasks will be caught up once your Mac wakes up.


Users can also use a custom script to wake up the Mac and put it back to sleep after scheduled tasks if needed.


You can then check the connection status in the sync-task’s “Readiness State” field. The connection should hold as long as ChronoSync is running in the background.
