ChronoSync Express is the entry-level version of the popular ChronoSync utility. It is the one application you can count on for both reliable backups and easy folder synchronization. ChronoSync Express combines an efficient file copy engine, flexible scheduling options, broad connectivity, and a robust user interface into the one utility that no Mac should be without. 

IMPORTANT: ChronoSync Express enjoys the added security benefits of running within the application sandbox, as is required for all Mac App Store apps. As a result, however, it differs from the standard version of ChronoSync by eliminating a few features such as embedded script execution and bootable backups. Full details can be found by clicking our website link.

At its simplest, just create a new Synchronizer Task, pick two folders, and synchronize! When you need more control, use the built-in Options to dictate how individual files are handled, create archives of deleted or replaced files, and customize error handling and notifications. ChronoSync Express brings professional-level features to a consumer-level product!

What’s New

Version 1.3.5

• Implemented additional logic when attempting to move files to the trash so that any restrictive ACLs are temporarily removed from the files to ensure success.
• Modernized the file lock/unlock routines.
• Disabled some irrelevant Readiness Warnings.
• Fixed a bug whereby, with a certain combination of task settings, the Analysis Report would fail to print the last page of the report.
• Fixed a bug whereby the auto-conversion of a sync task created pre-Catalina would potentially cause a hang if BOTH the source and destination targets were referencing the newly created ‘Data’ volume on Catalina.
• Fixed a bug whereby deleting a file from the archive during the maintenance phase of a synchronization would fail if the folder containing that file was locked.
• Fixed a bug whereby creating a folder in the archive during the course of a synchronization would fail if the parent folder in the archive was locked.

Excellent software, has saved me numerous times

This software is excellent. I highly recommend the full version which I use on my main system and this lite version I use everywhere else. I appreciate how simple and straightforward it is to set up a series of scheduled jobs and set a version history for the archive. Whereas Time Machine has failed me several times, because of permissions, versioning or some other idiotic nonsense, ChronoSync has made recovery of previous versions simple. It enables me to write my synced data to safer file systems where unix permissions behave consistently, like APFS and ZFS (Time Machine is still not capable) and recover the files regardless if my UID has changed, without having to enter some ridiculous 3D rendered full screen window.

This is Worth Every Penny You Pay for it

I had been looking for something like this. I just heard about this software on a podcast. It works beautifully. The best $25 I’ve spent in years. It backed up a Terabyte drive in a couple of minutes. It’s saves me tons of time backing up drives manually. Now, I can just do my work without thinking about backup. Backups happen automatically on two external G-Drives.

I have the software installed on my iMac which backups to two external hard drives. I also have the software installed on my macBook Pro for tethered shooting.

ChronoSynch Express

Affordable, easy to use and gets the job done. I'm glad I have this software on my iMac. I use it to Synch with my Image Library which is on a separate external drive. The initial Synch, of course, took several hours, but now when I plug it in weekly to update the Synch, it’s a matter of minutes and I know I have an exact copy of important digitial image files. Reassuring. Highly Recommend!
