Editors' Review


Carbon Copy Cloner is a simple, donation-ware utility for cloning entire drives, performing incremental backups, and scheduling ongoing backups. This app has a long track record as one of the most useful and reliable disk utilities available, and its interface and features (especially for scheduling) have only gotten better. Its also kept up with the Mac OS, adding support for HFS+ filesystem compression. Other recent updates have integrated support and documentation into the app better, speeded up recovery of files from damaged volumes, and ensured that Carbon Copy Cloner excludes the Time Machine database.

Carbon Copy Cloner makes it very easy to quickly clone a hard drive (i.e., duplicate every single file on the drive, even at the block level), or you can indicate which files and folders should be copied--and you can also direct it to only copy files that have changed since the last backup. Carbon Copy Cloner can help you schedule regular backups, too, according to any schedule you set, and it can also work with iPods and remote Macs. Carbon Copy Cloner may have a fairly narrow feature set (for example, you can't back up directly to optical disks), but it provides a lot of well-executed functionality at a low price.

"Fly in the ointment"

October 06, 2014  |  By mzulgis

Great product, works as advertised...


...unless you upgrade your Mac. Bombich are asking for money to upgrade to the current version just 5 months and 11 days after I bought it.
The version I bought in April 2014 will not run on my laptop so after just 5 months I am being forced into another purchase.

Full Specifications

What's new in version 3.3.4
  • Resolved an issue in which an error was reported if a file had 126+ Access Control Entries (ACEs).
  • Resolved an issue in which extended attributes were not reapplied to files modified since a previous backup.
  • Resolved an issue affecting Leopard users only in which the password specified for encrypting a disk image would not be recognized if the user did not click out of the password text field prior to clicking the Save button.
  • Resolved an issue in which the CCC.log file may be unwritable for the currently-logged-in user.
  • The text at the bottom of the Scheduler window now properly indicates that disabled scheduled tasks are not scheduled to run at a particular time.
  • Added a message to the end of an aborted block-level cloning task that informs the user to reformat the target volume in Disk Utility.
  • Improved the wording of some of the "What is going to happen" statements.
  • Resolved an issue in which CCC allowed a user to specify a directory as a pre- or post-flight script path (the path to an executable file is expected). This setting would subsequently cause CCC to report an error.
  • Resolved an issue in which CCC might hang while "Authenticating" or report an error while trying to run the first task that requires elevated privileges if the ownership of the /Library/PrivilegedHelperTools directory is amiss.
  • CCC now properly disallows the scheduling of a task that saves a disk image to the startup disk.
  • When using the "Archive deleted and modified items" feature, the timestamped folders are now stored in one folder at the root level of the target volume.
  • CCC now generates a warning when absolute paths are entered in the subfolder field of the Advanced Settings panel.
  • CCC now properly prevents you from trying to save a disk image in a folder to which you do not have write access.
  • Added a check for software updates to the end of the backup task for scheduled tasks.
  • Resolved an issue in which the "Data Copied" field would occasionally errantly report a very large number.
  • CCC now presents a more informative dialog when a block-level clone is stopped before it is finished. CCC now indicates that the target volume must be reformatted and presents a button that takes you to the Disk Utility application.
  • CCC provides better progress indication when converting a sparse disk image to a read-only disk image.
  • If the target directory does not exist on a remote Macintosh target, CCC now reports this condition before enumerating files.
  • Made several minor changes to the documentation to make it valid against XHTML Strict.
  • Adjusted the calculations behind weekly scheduling. Rather than having a week start on Sunday for all locales, the week will now begin on the date specified as the "Start on" date. Tasks scheduled with intervals greater than every week (e.g. every other week, every third week, etc.) will also more reliably determine the first and last days of the interval.
  • Scheduled backup tasks that specify a volume that is managed by autofs or automountd will now attempt to trigger those automounts.
  • CCC now indicates very clearly whether a Time Machine backup will be transferred.
  • Improved error messages associated with input/output errors to offer clear guidance on resolving them.
