CCC includes a command line utility that allows you to start, stop, and monitor the progress of specific CCC backup tasks. The utility is located inside of the CCC application bundle. To get basic usage instructions, invoke the utility without arguments in the Terminal application, e.g.:
user@Mac ~ % "/Applications/Carbon Copy Cloner.app/Contents/MacOS/ccc" ccc -v|--version Prints the version of the CCC command-line utility (this is not the same as the main application version) ccc -s"Task Name" | --start="My Backup Task" (-w|--watch) -w|--watch: Keep running and print task output until the task is finished. Ignored for task groups. ccc -x["Task Name"] | --stop[="My Backup Task"] [-r] Stop all tasks, or the specified task. By default the task is treated as if cancelled. Use -r to report the event (e.g. via Notification Center and, if configured, email). Use another non-zero value if you would like task notifications to be sent. ccc -h|--history [-c|-d] Print a summary of task history, i.e. the data you would see in the table at the top of the Task History window. -c prints in CSV format -d prints dates in seconds since Midnight Jan 1, 1970 (rather than formatting the date) ccc -p|--print-schedules [-c|-d] List each task and when it will next run. -c prints in CSV format -d prints dates in seconds since Midnight Jan 1, 1970 (rather than formatting the date) ccc -w["Task Name" | --watch[="Task name"] Watch task progress (press Control+C to exit) Specify a task name to limit task output to the indicated task ccc -i|--status Print a status line for each task. ccc -g|--global globalDefaultName [bool|int|float|string] globalDefaultValue Set a global default value. ccc -g|--global globalDefaultName delete Delete a global default value. ccc -n|--notification notificationTitle notificationBody Send a notification to the Notification Center. ccc -z["Task Name"] | --disable[="Task Name"] ccc -e["Task Name"] | --enable[="Task Name"] Disable or enable all tasks [or a specific task]. ccc -u | --uuids Print task names and their unique identifiers.
Here are some examples of how to use the CCC command-line tool to start and stop a task, and get its last history event:
