Reminder: Recovery HD volume cloning is not applicable to APFS-formatted destination volumes (i.e. Catalina and later)

Carbon Copy Cloner offers complete support for archiving, cloning, and recreating Apple's Recovery HD partition. See the Cloning Apple's Recovery HD partition section of CCC's Disk Center documentation for instructions to create a Recovery HD volume on your backup disk.

Frequently Asked Questions about encrypting the backup volume

Can I run a backup while I'm using my computer? If I have open files, will they be backed up?

Product: 
ccc5

Generally, yes. Performance will be affected during the backup task (especially the first one) as CCC reads the entire source volume and writes to the destination volume. If your work is "disk bound" — that is your applications are reading or writing to either the source or destination, then you'll notice a performance hit. If you're just reading email or writing a document, then you probably won't notice the performance hit.

I have a clone created by another application. Will CCC recognize that data, or will it want to recopy everything?

Product: 
ccc5

CCC always examines the files on the destination to determine if they already match those on the source. If you have a volume that is virtually identical to your source, CCC will copy only the items that are different between the two volumes.

Can I run my backups more frequently than Hourly?

Product: 
ccc4

CCC offers hourly, daily, weekly, and monthly scheduling options, which suits the needs of most users. Some usage scenarios, however, demand higher frequency backups. For example, photographers might prefer to have their SD cards offloaded to a tethered computer every 5-15 minutes during a photo shoot. When the shoot is complete, though, the backup task should not run at all. Special cases like these demand more flexible execution options, which can be achieved by leveraging CCC's built-in command-line utility.

Kann ich ein Backup eines Computers erstellen und mit dem Klon einen anderen Computer wiederherstellen?

Product: 
ccc4

Die Antwort dazu ist häufig wahrscheinlich schon. Es gibt jedoch ein paar Einschränkungen.

„Kann CCC meine Boot Camp (Windows) Partition sichern?“

Product: 
ccc4

CCC kann die Inhalte Ihrer Boot Camp Partition sichern, jedoch keinen bootfähigen Klon der Partition erstellen. Wenn Sie nur die Benutzerdaten aus Ihrer Boot Camp Partition sichern möchten, kann CCC Ihnen dabei helfen. Wenn Sie Ihre Boot Camp Partition auf eine neue Festplatte migrieren möchten, sollten Sie über eine alternative Lösung wie WinClone oder kommerzielle Virtualisierungslösungen mit Migrationsfunktion für Boot Camp nachdenken.

Can I run backup tasks while my system is on battery power?

Product: 
ccc4

CCC can run backup tasks while the system is running on battery power, but will not (by default) start automated tasks when your laptop is running on battery power. Backup tasks generate a lot of disk read and write activity, and that can run your battery down. Additionally, macOS tends to aggressively put the system to sleep when it's on battery power, causing task completion to be deferred until the system is awoken.
