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 4.9.6:
Changes & Enhancements:
  • The APFS Volume Group Converter utility is now capable of converting an HFS+ formatted volume to an APFS Volume Group.
  • If a download is in progress for an in-app-update when the application is quit by the user, the termination will be aborted and the download progress panel window will be brought to the front.
  • The Configured System Identifier readiness test can now be ignored to allow the sync task to be run on different systems without the warning preventing it from running.
  • Improved the Trial Key Retriever reliability on macOS 10.15, Catalina (or later).
  • Improved shell task execution reliability to better handle errors and exceptions.
Bug Fixes:
  • Fixed a problem whereby if "Launch at login" was enabled and so was "Use background scheduler," the Background Scheduler could conceivably be launched twice at login.
  • Fixed a long-standing bug whereby the results of running external commands and tasks could be misinterpreted because of failing to read the entire output/result from running that command affecting operations such as mounting Disk Images or Blessing bootable backup targets.
  • If running on macOS Catalina (or later), the Background Scheduler uses the UUID of the corresponding 'Data' volume to prevent a situation whereby an OS update causes a change in the UUID of the System volume.
  • If running on macOS Catalina (or later), the configured system identifier stored in Task Documents is derived from the UUID of the corresponding 'Data' volume to prevent a situation whereby an OS update causes a change in the UUID of the System volume.
  • Fixed a problem whereby a change to the System volume's UUID caused by an OS update could trick the mount detection logic for a given target to fail, forcing the user to re-select the target.
  • Fixed a bug whereby selecting a pre- or post- sync script could cause the application to crash.
  • Fixed a consistency problem whereby kilobyte file sizes and transfer rates were displayed with the K symbol instead of KB.
  • Fixed a bug whereby a file-folder pair (i.e. folder on one side, file on the other, both with the same name) marked for synchronization would not display a status icon in both the Analyze panel or the Trial Sync Selector sheet window.
  • Fixed a bug whereby a file-folder pair (i.e. folder on one side, file on the other, both with the same name) was likely to generate a folder enumeration error when running a Trial Sync (the error was benign if the user just ignored it).
  • Fixed a bug whereby auditing differences in a file-pair would not factor the file size in some circumstances resulting in the File/Folder Information in the Analyze panel failing to display a file size difference in red.
  • Fixed a problem whereby some some displayed file attributes in the Analyze panel would remain in cache after file entries were reloaded.
  • Fixed several bugs in the Synchronizer, Bootable Backup Assistant and APFS Volume Group Converter whereby errors and/or incorrect behavior would result if there was an existing APFS Preboot volume on the destination but it wasn’t spelled exactly 'Preboot' e.g. 'PreBoot'.
  • Fixed a Catalina-specific bug whereby file system observers would fail to detect deep file system changes if the root folder being modified resided on your boot system's 'Data' volume causing live triggered syncs not to run after deep file system changes were made.
  • Fixed a bug in our custom target selector whereby rapidly selecting folders before their contents were displayed could conceivably cause a crash.
  • Fixed a bug in our custom target selector whereby rapidly selecting folders could result in unnecessary fetches of folder contents and extraneous re-display of folder contents.
  • Fixed a bug in the APFS Volume Group Converter utility whereby it was assumed that the destination volume had ownership enabled but that isn't necessarily the case.
  • Fixed a bug whereby a copy task could be initiated with a user abort pending and the copy would have to fully complete before the abort was recognized.
  • Fixed a bug in the Backblaze B2 storage provider whereby move/rename operations on files larger than 5 GB would always fail.
  • Fixed a bug in the Backblaze B2 storage provider whereby move/rename operations on files that result in a timeout would get caught in a timeout loop until the move/rename operation succeeded.

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.

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.

The •combination• of ChronoAgent + ChronoSync is absolutely the best working system for backups and bi-directional syncing that I've found in my three decades of using Macs. The duo enable a smart-scan feature which performs incredibly fast. If you haven't tried running both together [i.e., with agents on target Macs], I highly recommend it. Great job, Econ Technologies! -HI-

This is a solid app, never crashes, full of features, and the price is right. $50 might seem like a lot for most but every upgrade is free for life. My only complaints are the update mechanism and a couple of not so intuitive UX choices.

Better than Carbon Copy Cloner for versioning files

I find CCC to be one of the best cloning and backup software. I have used it for many years with no single flaw. The bootable backup is very important.
I recently migrated to Chronosync because a few advantages (I still love CCC) that Chrono offers for my need: the most important of all is how the Archives are organized.
CCC organizes archives in a separate folder called "archives". Chrono puts archives inside the core structure of the backup. I find the Chrono strategy very useful to keep versions of files.
For CCC, finding the earliest version of one specific file requires browsing through hundreds of folders. In Chrono, they are kept together, numbered with version numbers.

To put it shortly, I use Chronosync both as my GIT/SVN (versioning) and as my cloning (backup) system.

I cannot prevent from highly recommending Chronosync. I own since 2012 and it never failed. The support is amazing. Quick and efficient. They are committed to help you whatever your questions. Use it for multiple purposes : -backups. They work better than Timemachine and never fail -synchronization of different disks in different places through the cloud or through external drive. A fantastic feature.
