• Does CCC have to be running for a scheduled task to run?
• What happens if no one is logged in when a task is scheduled to run?
• Will CCC run when the computer is turned off?
• Will CCC run when the my laptop's lid is closed?
• How is system sleep handled?
• Why does my laptop sometimes go to sleep during a backup task?

Note: The topics in this article are not relevant to APFS-formatted destination volumes that have CCC snapshot support enabled. For those volumes, CCC leverages snapshots to implement the SafetyNet functionality, and the snapshots aren't affected by any of the shortcomings described here.

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.

• Can I back up an encrypted volume to a non-encrypted volume?
• If I back up an encrypted volume to a non-encrypted volume, will the copied files be encrypted on the destination?
• Will Carbon Copy Cloner enable encryption on my backup volume?
• Do I have to wait for encryption to complete before rebooting from my production volume?

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.

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.

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.

Spesso la risposta probabilmente è Sì. In ogni caso abbiamo qualche avvertimento.

CCC può fare il backup dei contenuti della partizione Boot Camp ma non può creare una copia avviabile della partizione. Se vuoi creare un backup dei tuoi dati utente della partizione Boot Camp, allora CCC è quello che ti occorre. Se vuoi migrare la tua partizione Boot Camp su un disco fisso nuovo dovresti utilizzare una soluzione diversa ad es. WinClone o una delle soluzioni commerciali di virtualizzazione che offrono strategie di migrazione da Boot Camp.
