Configurer les conditions d’exécution des tâches programmées

La planification périodique ne suffit pas toujours à définir exactement le mode d’exécution des tâches. CCC propose des conditions d’exécution permettant de restreindre l’exécution des tâches programmées sous certaines conditions.

When I boot from my backup, Little Snitch reports that its rules have been replaced by a different version. Why, and how can I avoid this?

Product: 
ccc5

According to ObDev developers, it is crucial for Little Snitch to avoid unnoticed ruleset changes. Little Snitch therefore has numerous mechanisms to detect whether it is using the exact same ruleset file, as in, on the same volume and at the same physical address on that disk. This sort of mechanism makes it impossible for Little Snitch to use the ruleset on the booted backup volume without physical intervention from a user at the system (thus the dialog asking if it's OK to use the current version of rules or to use a default ruleset).

Creating a separate task to prevent VM container versions from bloating the SafetyNet

Product:

If you frequently use virtual machine container files (e.g. with Parallels, VMWare, VirtualBox, etc.), you may find that CCC's SafetyNet folder tends to get very large, very quickly. Every time you open your virtual machine, the monolithic virtual machine container file is modified, and CCC will require that it gets backed up during the next backup task. If the SafetyNet is on, CCC will move the older version of the VM container file into the SafetyNet folder.

Modifying CCC's Security Configuration

Product: 
ccc5

Rather than requiring you to enter admin credentials every time you want to run a task or make changes to a task, CCC only requires you to authenticate once when CCC is initially installed. While this configuration is easier to use, there are situations where this configuration is not appropriate. If you leave your system unattended with an admin user logged in, someone with physical access to your system can modify or run your CCC backup tasks.

Réglages avancés

Product:

Les réglages avancés de CCC sont destinés à des cas spécifiques. De manière générale, ils n’ont pas d’utilité particulière pour les opérations de routine. Certains d’entre eux ne sont pas sans risque, par conséquent soyez prudent et n’hésitez pas à poser vos questions via l’option de menu Poser une question sur CCC… dans le menu Aide de CCC si les explications qui suivent ne suffisent pas dans votre situation spécifique.

Pour accéder aux réglages avancés, cliquez sur Réglages avancés sous le sélecteur de source de CCC.

Exclure des fichiers et des dossiers d’une tâche de sauvegarde

Product:

Par défaut, CCC copie l’intégralité du volume ou du dossier défini en tant que source. Si vous ne souhaitez pas copier tous les éléments de la source, vous pouvez définir un filtre de tâche pour restreindre les éléments à copier.

Some files and folders are automatically excluded from a backup task

Product: 
ccc5

Carbon Copy Cloner maintains a list of certain files and folders that are automatically excluded from a backup task. The contents of this list were determined based on Apple recommendations and years of experience. The following is a list of the items that are excluded along with an explanation of why they are excluded.

Restoring from a disk image

Product: 
ccc5

You can access the contents of a disk image the same way that you access other volumes and external hard drives on macOS. Double-click on the disk image file to mount its filesystem, then navigate the filesystem in the Finder to access individual files and folders. If you have the permission to access the files that you would like to restore, simply drag those items to the volume that you would like to restore them to.

Backing up to/from network volumes and other non-macOS-formatted volumes

Product:

In addition to backing up to volumes formatted with the macOS standard HFS+ or APFS format (collectively referred to as "macOS-formatted" from here forward), CCC can copy user data files to network volumes (e.g. AFP and SMB via macOS and Windows File Sharing) and to other non-macOS-formatted volumes such as FAT32. Non-macOS-formatted volumes are presented in CCC's Source and Destination selectors in the same manner as macOS-formatted volumes, so there are no special steps required for backing up to or from these filesystems.
