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.

Puis-je sauvegarder un ordinateur et utiliser le clone pour restaurer un autre ordinateur ?

Product:

Souvent, la réponse est probablement oui. Cependant, il y a quelques mises en garde.

CCC peut-il sauvegarder ma partition BootCamp (Windows) ?

Product: 
ccc4

CCC peut sauvegarder le contenu de la partition Boot Camp, mais ne peut pas cloner la partition démarrage. Si votre but est de sauvegarder vos données utilisateur sur la partition Boot Camp, CCC vous conviendra. Si vous voulez migrer votre partition Boot Camp vers un nouveau disque, vous devriez considérer une solution alternative telle que WinClone, ou une des solutions commerciales de virtualisation qui offrent la possibilité de migrer à partir de Boot Camp.
