Cas d'utilisation

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.

Create a new task

Click the New Task button in the toolbar to create a new task, then type in a name for the new task.

Select a source volume

Click on the Source selector, then choose the volume that you want to copy files from.

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.

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.

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

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.
