Each time CCC performs a backup or restore task, the results and statistics of that task are recorded and displayed in CCC's Task History window. To view task history, click on the Task History button in the toolbar, or choose Task History from the Window menu.

Task History window

Task events can be filtered and sorted by task name, source, destination, start time or status. CCC will show up to 2000 task history events. Each event will indicate when the task started, how long it took, how much data was copied, the overall status of the task, and the CCC and macOS version at the time of the event. The color of the status indicator is defined as follows:

  • Green: Task completed successfully
  • Yellow: The task completed, but errors occurred while transferring some files
  • Red: An error occurred that prevented the task from completing
  • Gray: The task was cancelled

Audit: Viewing details about the modifications made by the backup task

When enabled for a particular task, 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. Each transaction will indicate the size and modification date of the file at the time of the backup, and the action that was applied to the item. A status icon in the "🤔" column indicates why the action was taken, e.g. a file may have been updated because its size or modification date differed on the source and destination. You can hover your mouse over this icon for detailed information about the differences that were noted for that particular item.

Viewing the current item on the source or destination, viewing older versions

Right-click on a transaction to view a contextual menu of options specific to that item. If older versions of a file are available in a snapshot, those versions will be listed in the Versions sub menu. Note that these options will be disabled if your source and destination volumes are not mounted.

Errors

There are many hardware and filesystem problems that could affect your Mac's hard drives. Filesystem and media corruption are commonplace, and CCC delivers expert advice to you when errors occur. CCC's Task History window shows the results of all of your backup tasks, and details of any errors that occur. CCC enumerates these errors, analyzes them for common conditions, then explains the problem in simple terms with down-to-earth advice for fixing the problem.

Exporting a list of affected files

If you would like to save a list of the affected files in the errors table, select the affected items (or press Command+A to Select All), then choose Copy from CCC's File menu (or Command+C) to copy the list of items to the clipboard. Please note that every error may not be the same. When you export a list of files, the per-file contextual information is not retained. Return to CCC's Task History window for the contextual information and advice specific to each file.

Getting help for common errors

When errors occur, CCC will categorize the error and offer troubleshooting advice. For some errors, CCC will offer helpful buttons at the bottom of the task history window that will, for example, take you to Disk Utility or reveal a corrupted file in the Finder. If the affected file is one that doesn't need to backed up, click the button to exclude the item from the backup task to avoid future errors on that file. Click on each error to see what CCC recommends to resolve the error. If you're stuck or overwhelmed, or if CCC's advice alone isn't helping you resolve the problem, click the "Help Me!" button to submit a summary of the problem to the Bombich Software Help Desk.

Can I remove events from CCC's Task History window?

To remove one or more task events from the history table, select the events, then right-click on the selection and choose Remove from the contextual menu. Removing task events from the Task History window has no effect on the backup, it only removes the event from CCC's Task History window, as well as any transactions stored in CCC's task history database. You must be logged in as an administrator user to delete task history events.

If you would like to clear all of CCC's task history, open the Task History window, then choose Clear Task History... from CCC's File menu.
