The current version of Carbonite backs up only files that reside on permanent hard drives in your computer. Carbonite will not back up network drives, external drives, or NAS (network accessed storage) drives. If you have files on these external storage devices that you want Carbonite to back up, they should be moved to the internal hard disk of your computer.

Files on Non-Permanent Drives and Carbonite

If there are files on a remote drive that you wish to include in your Carbonite backup, you should first copy the files to a folder selected for backup on your local hard drive. After they have been moved to the local hard drive, you can then select the files for backup by right-clicking on them and selecting Carbonite; Back this up (on a Mac you can back up files through the Carbonite Preference pane).

The files need to remain on your local drive in order to stay backed up. Deleting a file, or not keeping it on the local drive, will cause Carbonite to remove them from our secure backup servers within thirty days.

If the files are on a shared network drive, you could install Carbonite on the computer on which the network drive physically exists. Once installed, you can select the files for backup directly from that computer.

Check back soon for a Carbonite service plan that will allow you to back up your external drives.
