If you're using an application firewall such as Little Snitch, you will see several outgoing network connections coming from CCC. We explain below what connections you should expect to see, and also explain why some connections that look unexpected are simply misreported by Little Snitch.

Ordinary activity

CCC will make external network connections for the following activity:

If you frequently use virtual machine container files (e.g. with Parallels, VMWare, VirtualBox, etc.), you may find that CCC's SafetyNet folder tends to get very large, very quickly. Every time you open your virtual machine, the monolithic virtual machine container file is modified, and CCC will require that it gets backed up during the next backup task. If the SafetyNet is on, CCC will move the older version of the VM container file into the SafetyNet folder.

Rather than requiring you to enter admin credentials every time you want to run a task or make changes to a task, CCC 4 now only requires you to authenticate once when CCC is initially installed. While this new configuration is easier to use and has been requested by countless users, there are situations where this configuration is not appropriate. If you leave your system unattended with an admin user logged in, someone with physical access to your system can modify or run your CCC backup tasks.

Standaard kopieert CCC alles van het volume of de map die u als de bron opgeeft. Als u niet elk onderdeel van de bron wilt kopiëren, selecteert u “Geselecteerde bestanden” in het venstermenu Kloon onder de Bronkiezer. Geef dan de onderdelen op die moeten worden uitgesloten van de reservekopietaak.

De geavanceerde instellingen van CCC zijn handig in bepaalde situaties maar zijn doorgaans niet vereist voor normaal gebruik. Sommige van deze instellingen zijn risicovoller. Wees daarom voorzichtig wanneer u ze gebruikt en stel gerust vragen via de menuoptie Stel een vraag over CCC... in het menu Help als de onderstaande uitleg niet volstaat voor uw specifieke scenario.

CCC is fully qualified for use with FileVault-protected volumes. CCC offers some advice around enabling encryption in the Disk Center.

Enabling encryption on a volume that contains (or will contain) an installation of macOS

If your goal is to create a bootable, encrypted backup, use the following procedure:

CCC makes bootable backups specifically to avoid this kind of situation. When you have a bootable backup, you simply boot from that, then restore everything to a replacement disk or the original disk. One step, minimal time, couldn't be easier. Occasionally people get into this sticky situation though -- I have a backup of everything in a disk image or in a folder on the backup volume, there's a clean installation of macOS on my replacement disk, now how do I get everything back to the way that it was before?

Often when you have a backup task that runs on a scheduled basis, there are associated tasks that you would like to perform before or after files are actually copied. CCC offers the option to run shell scripts before and after a backup task, unmount or set the destination as the startup disk, run another CCC backup task, and power management options such as restart and shutdown. If you would like to perform any of these pre or post clone tasks, click on the "Use Advanced Settings" button at the bottom of CCC's window.
