Cas d'utilisation

Usually it's easiest to restore a single item from your backup by simply dragging it from the backup volume to your original source volume. Sometimes, though, it's not that easy. Suppose, for example, that you have inadvertently deleted all of your Safari bookmarks. The Safari Bookmarks file is stored in a hidden folder within your home directory, and the fact that this folder, and the folder on the backup volume are both hidden makes accessing that file in the Finder quite difficult. The steps below demonstrate how to restore this item from your Carbon Copy Cloner backup volume.

Il existe plus d'une raison pour effectuer un clonage exact d'un disque dur. Imaginez que vous deviez confier votre ordinateur portable à un service de réparation. Vous devrez éventuellement emprunter un autre ordinateur pour la durée de la réparation, sans pouvoir disposer de vos données, applications et environnement de travail exactement comme sur votre ordinateur. Une situation pouvant s'avérer très frustrante et inhiber votre productivité.

Les périphériques de stockage en réseau comme Time Capsule connaissent un succès grandissant depuis qu'ils fournissent un nuage de stockage personnel partagé. Ce type de stockage s'avère évidemment intéressant en tant que destination de sauvegarde. L'idée de sauvegarder tous ses contenus sans devoir brancher un seul câble est également très séduisante.

Create a new task

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

Backing up multiple volumes or multiple Macs to a single hard drive can be a messy proposition. If you back up each source volume to the same destination volume without some pre-planning, data from each source volume will be merged in a heap on the backup volume. Additionally, your tasks will archive or delete each other's backed up content. Carbon Copy Cloner can solve this problem! We lay out a few different scenarios and solutions below.

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.

No, CCC will exclude the Backups.backupdb folder during a backup task because Time Machine backup folders contains Apple-proprietary filesystem devices. Apple's recommended procedure for copying a Time Machine volume is documented in this Apple Kbase article.
