Editors' Review

Users working between multiple workstations may need to access the same file from different computers and back up data between them. ChronoSync for Mac is a welcome program for those users and syncs data quickly and securely.

The program offers a free trial version available with a 500-file transfer limit while the full version requires $40 to unlock. The setup of ChronoSync for Mac went smoothly despite requiring acceptance of a lengthy user agreement. Upon first starting the program up, the user can choose to open a complete user manual, which is a welcome addition to this type of program, as novice users may not understand all of the features. Technical support for updates was also present. Upon starting, the user interface was easy to decipher, with left and right transfer folders similar to FTP programs for server upload. The user can select to back up and sync between folders in the same device, or on a different computer linked via a network. Many options are available to restrict or permit syncing of certain files or criteria. The buttons for operating the program's main features were easy to locate, even if the instructions were not used. Actual syncing completed quickly and without error, as would be expected.

For those users backing up files between networked computers, ChronoSync for Mac performs well and offers all expected features.

Editors' note: This is a review of the trial version of ChronoSync for Mac 4.3.7.

Full Specifications

What's new in version 4.9.2

  • We now allow a bucket name to be specified on the Advanced tab of the AWS S3 Connection Profile editor and automatically display this as the only choice available when connecting to S3 with that profile.
  • The Backblaze B2 Storage Provider is now capable of establishing connections using Application Keys.
  • Enhanced Security.
  • The Open & Sync, Open & Trial Sync and Open & Validate operations now wait longer after opening the task document before issuing commands.
  • Tweaked how messages are posted to the synchronizer log at sync completion.
  • Adjusted the queuing and management of concurrent operations.
  • Implemented new console logging mechanism whereby we no longer redirect stderr and stout and instead log messages directly to ChronoSync-Console.log and ChronoSync-Scheduler-Console.log.
  • When executing shell tasks, we now capture stderr and forward any output to our console logs.
  • SFTP: Enhanced connection stall/drop detection.
  • SFTP: Enhanced diagnostic messages if logging is enabled.
  • Backblaze B2: A 403 error is now reported as "Disk quota exceeded" instead of "No space on device" since the error is generated when all transactions are used up.
  • Modified error handling for 'parameter errors' generated when pre-allocating space for large files.
  • When a preference pane is first displayed, we now explicitly remove focus from any controls.
  • Improved global exception handling.
  • Modified auto-quit behavior in certain situations.
  • Corrected some auto layout problems in various languages.
  • Tweaked the bootable blacklist to exclude more folders.
  • When un-mounting a volume and un-mounting a snapshot, we now try to prevent blocking indefinitely if the volume cannot be unmounted.
  • Added logic so that the "Show ChronoSync Menu" preference setting is asserted to NO if the Background Scheduler is not presently running. Attempting to change this value to YES will launch the Background Scheduler. If that fails, the preference value is not changed.
  • Updated various resources to transition away from using red text to present a duplicate folder/file name (and similar) warnings.
  • Implemented a change to how the standard file manager retrieves SpotlightComments from files.
  • Made a minor change to how Spotlight Comments are set by the standard file manager.
  • Enhanced diagnostic logging.
