Rather than requiring you to enter admin credentials every time you want to run a task or make changes to a task, CCC only requires users with administrative privileges to authenticate once when CCC is initially installed. While this configuration is easier to use, 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.

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:

Standaard kopieert CCC alles van het volume of de map die u als de bron opgeeft. Als u niet elk onderdeel op de bron wilt kopiëren, kunt u een taakfilter instellen om te beperken welke onderdelen worden gekopieerd. Kies Kopieer sommige bestanden in het venstermenu onder de Bronkiezer of klik vervolgens op de knop Taakfilter () om het venster Taakfilters te openen.

Soms is het plannen van taken op basis van een tijdschema niet voldoende om exact te beschrijven hoe u wilt dat uw taken worden uitgevoerd. CCC biedt startvoorwaarden, waarmee u het starten van uw taken kunt beperken onder bepaalde omstandigheden wanneer de taak normaal gesproken gestart zou worden.

According to ObDev developers, it is crucial for Little Snitch to avoid unnoticed ruleset changes. Little Snitch therefore has numerous mechanisms to detect whether it is using the exact same ruleset file, as in, on the same volume and at the same physical address on that disk. This sort of mechanism makes it impossible for Little Snitch to use the ruleset on the booted backup volume without physical intervention from a user at the system (thus the dialog asking if it's OK to use the current version of rules or to use a default ruleset).

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.

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.

Om de geavanceerde instellingen te openen, klikt u op de knop  Geavanceerde instellingen onder de bronkiezer van CCC.

Carbon Copy Cloner maintains a list of certain files and folders that are automatically excluded from a backup task. The contents of this list were determined based on Apple recommendations and years of experience. The following is a list of the items that are excluded along with an explanation of why they are excluded.

You can access the contents of a disk image the same way that you access other volumes and external hard drives on macOS. Double-click on the disk image file to mount its filesystem, then navigate the filesystem in the Finder to access individual files and folders. If you have the permission to access the files that you would like to restore, simply drag those items to the volume that you would like to restore them to.

In addition to backing up to volumes formatted with the macOS standard HFS+ or APFS format (collectively referred to as "macOS-formatted" from here forward), CCC can copy user data files to network volumes (e.g. AFP and SMB via macOS and Windows File Sharing) and to other non-macOS-formatted volumes such as FAT32. Non-macOS-formatted volumes are presented in CCC's Source and Destination selectors in the same manner as macOS-formatted volumes, so there are no special steps required for backing up to or from these filesystems.
