Reliable backups, drive clones, and folder synchronizations.

Overview

ChronoSync is the professional choice for periodic backups, bootable drive clones, and folder and file synchronizations. Target any device or folder visible in Finder such a volume, thumb drive, NAS, disk image, select cloud services, server or (with ChronoAgent) another Mac! Directly connect to Amazon S3 and Google Cloud Storage cloud services and SFTP file servers. ChronoSync replaces your backup utility, drive clone utility, and folder sync utility with a single, powerful application. Get push notifications of your syncs sent to your phone with ChronoMonitor. Add InterConneX (free for iOS) and use ChronoSync to push files and folders to your iDevice.

What's new in ChronoSync

Version 4.9.11:
Changes & Enhancements:
  • Modified Bootable Backup sync task behavior to account for macOS 10.15.5 not allowing creation of valid firmlinks. On macOS 10.15.6+ ChronoSync provides the 'Fix' Readiness option to configure the required valid APFS Volume Group. On macOS 10.15.5 systems, the backup volume must be erased using the Bootable Backup Setup Assistant to create the required APFS Volume Group for Bootable Backup.
  • Altered the logic so that sub-second timestamps have to differ by 2ms or more for a file-pair to be considered different when comparing package file contents.
  • Added the ability to detect if a connected ChronoAgent implements the firmlink creation to allow Remote Bootable Backup on ChronoAgent connections.
  • Added logic to allow instantiating sync task documents in-memory if for some reason the underlying macOS system doesn't allow document creation read from storage/disk.
  • The Google Cloud connection profile type is no longer available to users UNLESS an existing Google Cloud connection profile is defined. In this case, the user is able to edit and create Google Cloud profiles, but they won't work due to API changes on Google's side.
  • The Bootable Backup Readiness Test now generates an error if the source target of a bootable backup resides on a macOS 11 (aka Big Sur) or later system.
  • Added the ability to specify a custom location for mounting APFS snapshot volumes via the 'Snapshot_Mount_Folder' plist setting on macOS 10.15 or newer.
  • Snapshot mount points now use 0755 permissions.
  • The Bootable Backup Assistant does not present source volumes with Big Sur (or later) installed on them as potential sources for a Bootable backup operation.
  • Applied fall back logic to all error conditions that occur when attempting to obtain attributes for an item.
  • Improved recognition of the active System component of the boot APFS volume group and its Data counterpart.
  • Increased the priority of the Bootable Backup Readiness test so that it is evaluated before many other readiness errors and reported to the user before other terminal conditions.
  • If a bootable backup operation encounters an error when running the UpdatePreboot tool, the entire output generated by UpdatePreboot is dumped to the ChronoSync-console.log.
  • Snapshot mount points are now created by the ChronoSync process instead of ChronoAgentLocal on macOS 10.15 or newer.
  • Determining if volumes are mounted is now done in a more Big Sur compatible way.
  • Modified the console messages produced when post-processing a bootable backup to provide a clearer idea of what is happening when diagnosing problems.
  • Changed the package aggregation algorithm to improve bulk file and folder attribute collection.
  • Added the ability to collect diagnostic messages when invoking the Restore operation.
  • Modified the Validator date compare to take into account date value rounding that can occur.
Bug Fixes:
  • Fixed a bug whereby deleting a task document from the Organizer window would not delete any scheduled items that are referencing that task document.
  • Fixed a bug whereby interpreting millisecond timestamps attached to files on APFS filesystems was subject to a scaling error when converting between time representations. This could result in unnecessary file data copying.
  • Fixed a bug whereby the Volume Group Converter would raise exceptions and fail to completely convert a single volume to a volume group if the user just previously retargeted their destination and opted to preserve sync history.
  • Fixed a bug whereby the Volume Group Converter wouldn't work correctly in some right-to-left scenarios.
  • Fixed an error handling bug when collecting attributes to force a rescan of the directory contents instead of causing an immediate fatal error.
  • Fixed a bug when collecting attributes for directory contents and identifying items that should remain invisible to apps and be ignored.
  • Fixed a bug whereby if a sync task document window is open, and the completion summary sheet is displayed, scheduled synchronizations for that sync task will fail because the summary sheet does not get auto-dismissed.
  • Fix for a cosmetic problem displaying checkboxes in the Trial Sync Selector on Big Sur.
  • Fixed a bug regarding priority of Readiness Tests when working from a saved sync task document.

Hard to add anything to all the positive reviews... ;-) What I like most is the transparent multi-sync procedure (when you set up multiple sync documents and launch them with a container), it also connects to remote drives with no hiccup. If ChronoSync meets some error, it generally offers a way to fix it either by changing a setting for you or by ignoring the offending file. The only thing I really regret is that I can't find any place where it would tell me how much data has to be synced — or was actually synced — as Synchronize Pro X did.

Poor customer support for a problem allegedly fixed in the latest release. An additional issue cropped up too. Developer rudely refused to look into either problem in spite of following all their instructions, then providing logs and screenshots. Avoid.

I have been an Apple Consultant for nearly 40 years and I have to say ChronoSync is AMAZING. It has been in my list of necessary software for my clients since you first released it. Every time I throw a task at it, ChrosoSync comes through with flying colors. Today the task was to copy files from a server via SSH to a local drive, then archive the files to another offsite server. It couldn't have gone any easier or straight forward! The Analyze and Rules sections help a great deal with only backing up what was needed and skipping any live databases. The Color tagging of tasks and containers made it very easy to follow in the Organizer. Grouping each task in a Container made reporting simple. Lastly, ChronoMonitor let us know that everything was working. Thank you to everyone at econ for creating AND innovating such an outstanding product.

It will do much more, but I use ChronoSync for one thing: Archiving files, photos and videos onto an external drive and replicating the original to several other drives. With minimal setup, the process is one-click easy and super fast. A great product to have if you're paranoid about losing your electronic valuables. The bonus: New versions are easily installed and don't cost you a cent.

If you are upgrading to Catalina, it is extremely important you follow the recommendations from Econ Technologies regards using ChronoSync (CS). They sent an email to all registered users, they point to a Catalina specific tech note at https://www.econtechnologies.com/chronosync/TN-CS-Catalina-Update.html READ it, heed it. Significant changes to APFS in Catalina. We should remind ourselves that Econ Tech does NOT charge for software updates, even though with every release of macOS, significant changes from Apple are made that require significant testing and changes in CS; kudos to Econ. Personally, I always do clean installs of a major macOS change; yes, it means more time reinstalling apps, configs and data, but having done hundreds of osx/macOS updates on countless mac models going back to 10.0.0, this method has proven to be the best in terms of eliminating post update issues.

I'am currently using Chronosync to backup some of my data to external drives. It finctions perfectly with an high level of customisation (exemple: I use flags and comments to select my files). Now I have in project to - synchronize my data with Apple's iCloud Drive (without Chronosync) - backup my data to the Cloud with Chronosync + Backblaze B2 (or maybe Wasabi). I'm testing... I had some questions but EconTechnologies was as usual very fast and efficient to give me responses...

Complete Mac backup cloning works like a champ, and is lightning fast! Tech support was very responsive and answered my two questions very quickly. I highly recomend this software and company.

I use this on a daily basis. It's very user friendly and does everything I want it to. I never have to worry about losing any of my data, ever, thanks to Chronosync. Oh, and you can't beat free updates for life.
