Carbon Copy Cloner 4.1.8 – Easy-to-use backup/cloning utility.

Carbon Copy Cloner 4.1.8

Carbon Copy Cloner backups are better than ordinary backups. Suppose the unthinkable happens while you’re under deadline to finish a project: your Mac is unresponsive and all you hear is an ominous, repetitive clicking noise coming from its hard drive. With ordinary backups, you’d spend your day rushing out to a store to buy a new hard drive and then sit in front of your computer reinstalling the operating system and restoring data.

With Carbon Copy Cloner, your data and the operating system’s data are all preserved on a bootable volume, ready for production at a moment’s notice. When disaster strikes, simply boot from your backup and get back to using your Mac. At your convenience, replace the failed hard drive and then let CCC restore the OS, your data and your settings directly from the backup in one easy step.

Any backup application can save your stuff. A CCC bootable backup will save your productivity too!

What’s New

Version 4.1.8:

  • The CCC command-line application now has an option to print the task history in CSV format.
  • The CCC command-line application can now be invoked to send CCC-badged notifications from a shell script.
  • Added a "Task Configuration" token to the Email Template.
  • An exit status of 104 will now cause the global preflight script to cancel the backup task and avoid recording a task history event.
  • CCC will now proactively seek out case conflicts on the destination when the source is a case-sensitive volume and the destination is not. When case conflicts occur in filenames, CCC will append a randomized suffix to the conflicting files on the destination (but all files will be copied). When a case conflict occurs in a folder name, the conflicting folder will not be copied. In every case, CCC will report case conflicts at the end of the backup task and offer advice for resolving the issue.
  • Some network volumes incorrectly report themselves as case-insensitive despite being backed by a case-sensitive volume. CCC now tests for case-sensitivity on network volumes rather than trusting the value that is reported in their volume attributes. With this change, CCC can now report potential case-conflict scenarios more consistently to the user when configuring a backup task.
  • Made some improvements to SMTP account importing from the Internet Accounts database (El Capitan only). Also added an "Edit" button next to the SMTP account popup menu to make it more obvious how to edit those settings.
  • Made some improvements to the presentation of Gmail authentication failures. CCC will now walk the user through the process of creating Gmail app passwords when two-step verification is enabled on the user's Gmail account.
  • Added an "Always show progress window" option to the CCC menubar application menu. That option will always be available now, and closing the mini task progress window will not change that setting.
  • Added new task history status icons that should be easier to distinguish for users with color vision deficiency.
  • Fixed an issue in which the mini task progress window would never be visible if the user had checked the "Hide" button next to CCC User Agent in the Login Items tab of the Users and Groups Preference Pane.
  • CCC will now proactively request that the user restore AC power when performing a Recovery HD cloning task. CCC, nor any application, cannot prevent the system from sleeping when running on battery power.
  • CCC's privileged helper tool will now dissent a request to unmount a volume if it is currently removing a SafetyNet folder from that volume.
  • The free space threshold for deciding whether to compact a sparse disk image is now 25GB or 15% of the capacity of the destination, whichever is larger.
  • CCC will wait longer for a preflight disk image compaction task to complete to accommodate slower destination volumes.
  • You should never move an application (e.g. from your Downloads folder to the Applications folder) while that application is open. Previously, doing so with CCC could cause it to crash. CCC will now detect if the CCC application file has been moved while CCC is open. If the selected task has unsaved changes, CCC will automatically move the application back to its original location. If that fails, or if there are no unsaved changes, CCC will present a dialog, then quit and reopen itself from the new location.
  • The options to not report an error when the source/destination is missing and to run the task as soon as the missing volume reappears were not previously available to tasks configured to run "Manually when I click the Clone button". That was appropriate, except in one case - when that task was invoked via task chaining. Now those options are made available to manual tasks, but only when those tasks are called via task chaining.
  • / and /.quota.user are now excluded from the backup task because changing those items on the destination causes the kernel to dissent unmount requests.
  • Made some improvements to the auto-dismissal of the task finished overlay that's presented within the Task Plan when the selected task has completed. In some cases, that information would be presented, then revoked before the user had a chance to read it. Now it will remain until dismissed.
  • Fixed an issue in which CCC would errantly unmount a FUSE volume at the end of the task if it was mounted with the allow_root flag and mounted by the root user (e.g. with "sudo").
  • Addressed an issue in which the reminder associated with tasks configured to run on reconnect could be presented earlier than expected.
  • Improved error handling if errors occur during the attempt to mount a disk image when choosing "Restore from disk image" from CCC's Source selector.
  • Fixed an issue in which the user could modify a task in CCC, then run the task via the CCC menubar application (which is a separate application from CCC). The task would run with the old settings, though the editor would present UI that suggests that the task is running with the new settings. Now if the user tries to run a task in the edit state via the menubar application, the menubar application will refuse to start the task, present a dialog indicating that the task is being edited, and will then open CCC.
  • Fixed a window resizing anomaly that could cause the source selector to be inaccessible.
