  • Fixed an agent communication bug whereby errors generated when obtaining the results of an asynchronous command that itself did NOT generate an error would not pass up the call chain.
  • Fixed a bug whereby if a folder enumeration error occurred on a non-empty, leaf sync node, the sync processing would not flag & respond to the error.
  • Fixed an auto-layout bug that could clip the "When deleting files" label.
  • Fixed a bug whereby changing targets on a previously run synchronization could result in a crash.
  • Fixed a bug whereby folders that have the UAppend, UChg, SAppend or SChg BSD flags set would not have their modification dates preserved.
  • Fixed a bug whereby a sync document that was maintaining an archive, but then had archiving disabled, would still factor in the maintenance scan count in the progress reporting.
  • Fixed a bug that could misrepresent the "% full" value displayed in a target's setup pane if the target volume were extremely large.
  • Fixed a bug whereby if ChronoSync need to update an alias file after it had been copied, it would not do so using bookmark-style aliases.
  • Fixed a problem that occurred when renaming files on certain NAS devices.
  • Enhancements:
  • Compatible with the latest versions of ChronoAgent (1.6.0) and InterConneX (1.2.1).
  • Improved SmartScan performance when connected to a ChronoAgent.
  • More efficient "Optimal host routing" logic.
  • Enhanced recovery from broken/bad network connections (when connected to ChronoAgent).
  • More optimal WAN settings are used when connected to a ChronoAgent over the internet.

  • Now tries harder to preserve sync state history after changing connection profiles.
  • More efficient display of entries in the Trial Sync Selector window.
  • Displays the correct remote machine icon when connected to ChronoAgent v1.6.0 or later.
  • Fixes:
  • Automatic exclusions at root level of volumes were not working.
  • More accurate updating of readiness messages when a target connection state changes and/or failures.
  • Any backup that targeted the root level of the boot volume would not reconstruct alias files that get copied.
  • Closing a sync document window within 1-2 seconds of sync completion could potentially cause a crash.
  • Archive deletion and restore operations did not have their initial log entries bookmarked.
  • User/group mapping on a ChronoAgent connection could be temporarily disabled when encountering large folders and updating the the Sync Document UI at the same time.
  • The "Saving..." progress indicator at sync completion was not visible on Yosemite & El Capitan systems.
  • In rare instances, closing a sync document window while actively editing text in a field could have caused a crash.
  • A flaw in the networking logic could have terminated active connections erroneously.
  • The Document Organizer was erroneously displaying duplicate entries after performing duplication & rename operations in a certain sequence.
  • The Sync Log window could not be opened in the midst of performing a Restore, Delete or Archive Restore operation.
  • Eliminated some long stalls that could occur when a large number of files were selected on the Analyze Panel and those files changed state in the file system.
  • If opening a bootable backup document that could not connect to either target, it was possible the document would spontaneously change to a ‘regular’ (non-bootable) backup.
  • A layout problem with the readiness popover window could clip its content.
  • Fixed a bug that was sometimes causing scheduled syncs to crash at the end of a synchronization.
  • Fixed a bug where post-sync tasks including emails, local notifications, push notifications and post-sync scripts were being improperly executed.

Full details can be found in the 'ChronoSync 4.7.0 Enhancements, Tweaks, and Bug Fixes' tech note.

  • Amazon S3 and Google Cloud services support added.
  • Added SFTP Server support.
  • New disk image mounting options.
  • Added Progressive Scanning functionality in the 'Special File/Folder Handling' options.
  • 'Smart' Readiness warnings added so you can either choose to fix or ignore the displayed warnings.
  • Support for encrypted volume mounting.
  • All-new connection profile architecture.

Enhancements:

  • Significantly improved performance when syncing with Google Cloud Connections. Depending upon sync contents, up to a 20% improvement can be realized.
  • Significantly Improved performance when syncing with Amazon S3 Cloud Connections. Depending upon sync contents, up to a 20% improvement can be realized.
  • Improved tracking of DMG volume location to better handle mounting and unmounting DMGs as well as the volumes they reside on.
  • Tweaked bandwidth limit calculations to more accurately match desired limits set in Connection Profiles.

Bug Fixes:

  • Fixed a bug that could cause a crash anytime after opening a Container Document even if the Container has since long been closed.
  • Fixed a bug whereby if a DMG on a file server were un-mounted by ChronoSync, the file server would not be un-mountable.
  • Fixed a bug whereby if targeting a DMG on a file server using “Mounted Volumes (Admin Access)”, the server containing the DMG would not get automatically mounted.
  • Fixed a problem in Admin Access that could result in a crash under ideal timing circumstances.
  • Fixed a bug whereby the readiness manager would erroneously state “You cannot perform a bootable backup with the current boot volume as your destination.” when switching between Bootable and Bootable Mirror operations with the same direction.
  • Fixed a bug in the Log Window whereby if you opened a log for a synchronizer document, then closed it while the sync was running (and generating log entries), then re-opened the Log Window, it would not ‘snap’ to the bottom of the log window.
  • Fixed a minor problem with Drag & Drop to the Scheduled Documents Manager Window.
  • Fixed a minor problem in the Registration Window and license key validation.
  • Fixed a problem whereby customers were being prompted for a Keychain Password.
  • Fixed a problem in Amazon S3 Cloud Connections whereby it was not properly setting the maximum number of concurrent operations.
  • Updated Online Help so terminology is more consistent with terms used in the App.

Enhancements:

  • Incorporated security updates and minor bug fixes to support SFTP protocols.
  • Added additional connection tracing options for the AWS S3, Google Cloud and SFTP connection profiles.
  • Improved the detailed log messages that are generated when diagnostic logging is enabled for AWS S3, Google Cloud and SFTP connection profiles.
  • Added the “Ignore resource fork errors” option to the SFTP connection profile. When ON, any attempt to write resource fork data to files will silently fail, allowing data forks to be written and syncs to proceed without error.
  • Added an “Edit” button next to the connection popup in the target panes of the Setup panel. Provides a convenient way to edit a connection profile. Only appears if the connection profile is editable.
  • Added localized Spotlight keywords to the app bundle’s info.plist file.

Bug Fixes:

  • The SFTP connection now better handles generic error codes during the connection/pre-configuration process instead of failing to connect.
  • The SFTP connection falls back to using “/“ as the initial directory if the server returns errors when trying to set the initial directory.
  • Fixed a bug in the SFTP connection profile editor whereby opening an existing profile would immediately advance the focus to the Password field if Password authentication was configured.
  • Improved Target verification to prevent concurrent verification of the same target which, in some instances, can cause problems resulting in incomplete scheduled synchronizations.
  • Fixed a problem where it was possible that targets were not verified prior to synchronization. The synchronizer now forces verification of targets before running.
  • Fixed a crash that could occur when the partition scheme information about a volume raised an exception.
  • Addressed a misleading tooltip for the “Preserve resource forks” option.
  • Eliminated a crash that could occur when closing a sync document window shortly after activating it.
  • Fixed a visual artifact that occurred with Container Sync documents on Sierra when opening a document on the Documents panel and switching to the Options panel where big black rectangle would appear as the controls were added to the window.
  • Fixed a bug related to SmartScan and old sync documents that did not record the ‘lastDataSize’ property of synchronized file-pairs. This problem only happens if an old sync document were ‘upgraded’ to include the Data Size trigger.
  • Fixed a minor leak in the local agent connection profile that would leak the agent password every time it was retrieved from the keychain.

Miscellaneous:

  • The Document Organizer does not allow dragged sync documents to be dropped on other applications. This prevents a potential problem where a sync document could be unexpectedly moved.
  • Updated the target description displayed on the Target Pane of the Setup Panel to be more readable.
  • We now wait up to 30 seconds for an encrypted volume to mount after it has been unlocked.
  • Added and updated several localizations.
