Carbon Copy Cloner 6.1.1 (7323)

Carbon Copy Cloner 6.1.1 (7323)

CCC 6 offers unprecedented accountability for your backup tasks, plus a brand new file copier that's faster, smarter, and designed to adapt to Apple's fast pace of OS and filesystem innovation. Combined with a sleeker, modern interface, we think you're going to love this new version of CCC.

What's new in CCC 6?
Faster backups with our next-generation file copier
We've completely rebuilt our file copier to take advantage of the performance characteristics of modern storage. Built on a multi-threaded design, our new file copier provides a foundation for many of the new features noted below, and paves the way for many new features in the future.

CCC Dashboard: The new menubar application
CCC's menubar application has gotten a complete makeover. The new "Dashboard" offers one-click access to starting, stopping and monitoring your CCC tasks, plus details about recent task activity.

The Dashboard also gives you a heads up to snapshot disk usage on the startup disk. Have you ever deleted files from the startup disk, emptied the Trash, then wondered why the space wasn't freed? Many people have been blindsided by the creation of snapshots on the startup disk – by CCC, Time Machine, and even macOS. CCC's Dashboard tracks the disk usage consumed by snapshots. If a sudden change occurs, or if disk usage is exceeding expectations, CCC raises the change to your attention so you can address the root of the matter.

Snapshot Navigator: Easy way to explore older versions of files
Looking to restore a specific version of a file? CCC's Snapshot Navigator allows you to step through older versions of your backups and get a preview of your files as they were at specific points in time.

Redesigned Interface with Dark Mode
CCC v6 includes a new, cleaner user interface. We reorganized the main window to make it smaller while making many of the controls and font sizes larger. We completely redesigned every window in CCC; revisited every button, every icon, and every color decision to offer a high quality Dark Mode experience. CCC now offers more detailed progress indication while a task is running, including a time remaining estimate. File processing and transfer rates are now charted live during backup tasks. Hover your mouse over the chart to view the current write rate (white) and files evaluated per second (green).

Quick Update: Leveraging FSEvents for super quick updates to the destination
Did you know that macOS keeps track of changes to folders? CCC 6's Quick Update taps into this service (called "FSEvents") and the result is lightning quick updates to your backups - no exhaustive scanning for changes required. When Quick Update is enabled for a task, CCC will ask the FSEvents service for a list of folders modified on the source since the last backup rather than scanning every folder for changes. The performance benefit of this feature cannot be understated, we've seen up to 20X improvement to backup time, especially for tasks involving a destination network volume.

Compare: Visual comparison of the source and destination
You've finished your backup but the source and the destination aren't exactly the same size; did CCC miss something? Probably not – the disk usage of your source and destination are usually different, but what are the specific differences?

CCC's Compare feature offers a visual comparison of your task's source and destination, and provides details if the differences are the result of a task filter. Use this feature to quickly determine if something is missing from the backup, or if folder size differences are simply the result of files sitting in the Trash.

Task Preview: See what changes CCC is going to make before actually making them
If you've ever been nervous about what changes CCC may make on a destination volume, you can use the new Preview feature in CCC 6 to see what's going to happen before making the changes. This "Dry Run" is available via the Preview button in CCC's toolbar, and any time you save a task for which the SafetyNet feature has been disabled.

Backup Audit: Task History events include a list of transactions
What was copied, and why? You asked for this, and we're delivering it with style in CCC 6. When your tasks run, CCC will record detailed information about the transactions that occurred during the task, e.g. files copied, files updated, folders created or updated, files deleted or archived. You can view these backup audits in CCC's Task History window, and never again wonder why CCC copied a particular file.

New scheduling option: Run a backup task "When files are modified on the source"
Using the same underlying technology that’s used by the "Quick Update" feature, CCC 6 offers a new automation option that allows you to have a task run when a threshold of data changes have occurred at the source. So rather than hourly or daily, etc., the task will run after 5GB’s worth of data has changed (for example). You can throttle that with a time limit as well, e.g. don’t run the task more than once every 5 minutes.

Advanced File verification
Previous versions of CCC have included the exhaustive "Find and replace corrupted files" option, but that option has a couple shortcomings that we wanted to resolve. CCC 6 can verify files at the end of the backup task, and also offers the opportunity to verify files on the source and destination, independently, against a hash that was recorded when the file was last copied.

Verifying the integrity of the source or destination

CCC 6 stores the modification date, size, and checksum of every file that was copied by a particular task. On demand, you can ask CCC to evaluate files on either the source or destination (independently of the other volume) against historical checksums. This gives you the opportunity to not only verify the integrity of the backup, but also to verify the integrity of the source.

Verification of files that were copied by the current task event
If you've ever migrated data to a new disk, you've probably wondered, "How do I know that all of the data was actually copied?" You may also not have realized that media sector failure is most often discovered on read, not on write, which means that data corruption that occurs on the new disk isn't usually discovered until some time in the future when you try to re-read the files. This new Advanced Setting offers a new postflight task option to verify files that were written to the destination.

Other new features and improvements
Our to do list never ends, and we're constantly receiving great feedback from users on how we can improve CCC.

Here are just a handful of simple improvements that we're excited to introduce in CCC v6:

  • Per-task control over the file copier's CPU usage.
  • You can temporarily pause a backup task.
  • More information about your source and destination right at your fingertips – click on the source or destination selector to see extensive information about the selected volume.
  • Refined Simple Mode – quitting and reopening CCC to switch modes is no longer necessary.
  • Items that cause task errors can be excluded directly from the Task History Errors table.
  • CCC's Task Filter now offers support for respecting macOS "backupd" exclusions (i.e. exclusions defined for Time Machine).

What's New:

Version 6.1.0:

  • Fixed an issue in which CCC was unable to create files and folders in some OneDrive-related folders on the destination.
  • Added an option to reveal the Advanced Settings persistently in the main window.
  • Added a contextual menu to the CCC menubar icon for "quick access" functions (e.g. open CCC, run a task, quit the Dashboard). Right-click on the CCC menubar icon to access this menu.
  • Added navigation buttons to the CCC toolbar to make it easier to get back to a task after making volume configuration changes (e.g. when adjusting snapshot settings).
  • Added an option for a light background for the sidebar (i.e. in Light Mode).
  • Added settings to choose a specific appearance (i.e. light or dark, independent of the system setting).
  • The Source and Destination selectors are now enabled while a task is running. You can click on these to see details about the source and destination (e.g. disk usage, free space) as the task progresses.
  • Task History events now show information about how many files and how much data was removed from the destination (in addition to how many files and how much data was copied to the destination).
  • Every Mac that is supported by macOS Catalina has native USB 3.0 support, so now CCC's Copy Coach proactively warns when a source or destination is connected via USB 2.0 (e.g. due to using an old USB hub or non-USB 3.0 compliant cable).
  • The Dashboard now shows both "last run time" and "next scheduled run time" for each task. Previously this was an option, but presenting both at the same time seems to be what most people are looking for.
  • Enhanced the search feature in the CCC Documentation window to offer an option to search the current page for matching text, or to execute a search of the entire CCC Kbase.
  • Task groups can now be specified via the "Run another task" option in Advanced Settings > Postflight.
  • Fixed a minor apparent discrepancy when using the "Verify files copied by this task" feature on a NAS volume. Previously this would show size-based differences due to the absence of extended attributes despite that those were deliberately not copied.
  • Audit records can now be exported to a CSV file.
  • Added a "Copy Link" option to the Tasks contextual menu. These links will open CCC and select the applicable task. These can be useful alongside other Mac automation.
  • Fixed a couple conditions where CCC would report an error and fail to create a symlink becase a folder with the same name already existed on the destination. Fixed a similar issue where CCC was unable to create new folder on the destination because a file (often a symlink) with the same name already existed.
  • Fixed a mouse tracking issue in the CCC Dashboard "mini progress" window that could make it impossible to click on the pause/stop buttons.
  • The CCC Dashboard window size and placement is now retained across launches.
  • Made a handful of adjustments to how older versions of files are presented in the Snapshot Comparison Browser. Checksums are now calculated on-the-fly for any files smaller than 2MB.
  • The System exclusion limit is no longer applied to a subfolder destination when the source OS is Big Sur or later.
  • Made some adjustments that should improve performance when using an ExFAT or NTFS volume as a source or destination.
  • Made some modest improvements to the "time remaining" estimate. This estimate will now include componesation for time that that will be required for re-verifying files that were copied (if specified for the task).

I can confirm that Carbon Copy Cloner does work as a full version after disabling SIP. (My Gatekeeper had already been turned off prior.)

To disable SIP, do the following:

Restart your computer in Recovery mode.

Launch Terminal from the Utilities menu.

Run the command csrutil disable.

Restart your computer.

FYI: System Integrity Protection (SIP) in macOS protects the entire system by preventing the execution of unauthorized code.
