Time Capsule and other network storage appliances are very popular for providing shared "personal cloud" storage. Naturally, this storage looks very appealing as a backup destination. The thought of backing up all of your stuff without having to plug in a cable is very alluring. "Convenient" and "fast" often go hand-in-hand, but that often is not the case when backing up to a network volume. There are several factors that can greatly reduce the performance of your backup, and this backup strategy encounters several of them.

Backing up your data to a network volume

Before you proceed, your NAS volume should be mounted and accessible in the Finder. Instructions for gaining access to network volumes is available in the macOS Help Center. If your network volume does not appear in CCC's Source or Destination menu, consult the documentation that came with the storage device you are trying to access, or choose "macOS Help" from the Finder's Help menu and search for "connecting to servers".

To back up a folder to a NAS volume with CCC:

  1. Choose Choose a folder from the Source selector.
  2. Select the folder that you would like to back up as the source
  3. Choose Choose a folder from the Destination selector
  4. Navigate to your NAS volume, then click the New folder button to create a new folder on this volume, e.g. named "CCC Backup". Click the OK button.
  5. Click the Start button to run the task immediately, or schedule the task to run later.

Note: If you select your whole startup disk as the source to a task that backs up to a NAS volume, CCC will automatically exclude all system-related content. Generally when backing up to a NAS, you should drag a specific folder onto CCC's Source selector to reduce the scope of the task.
