Can I use CCC to copy a Time Machine backup?

No. Copying a Time Machine backup volume with anything other than the Finder is not supported (by us, nor Apple); CCC specifically disallows copying anything to or from a Time Machine backup volume. Apple does not document a procedure for making copies of Time Machine volumes.

I have a backup created by another application or an older version of CCC. Can CCC update my existing backup?

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.

Folder-to-Folder Backups

When you select a volume as the source and destination, CCC copies the entire contents of that volume (minus anything you exclude) to the destination volume, preserving the full hierarchy of folders on the source. If you don't want to preserve that hierarchy, you can back up a specific folder from the source to a specific folder on the destination. In this configuration, CCC will copy the contents of the selected folder to the selected destination folder, without the hierarchy up to that source folder.

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

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.

We often see backup tasks configured with the whole startup disk selected as the source, and then everything excluded from the backup except for a single folder. This kind of configuration is suboptimal for several reasons:

Backing up Trash content

CCC will not back up the contents of Finder's Trash by default, but CCC 5 offers an option to back up the Finder's Trash in the Task Filter window. Choose Copy Some Files from the popup menu underneath the Source selector to reveal CCC's Task Filter window.

Posso eseguire il backup di un computer e usare il clone per ripristinare un altro computer?

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

CCC può fare il backup della mia partizione BootCamp (Windows)?

Product:

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.
