Finally, you need a high-capacity USB key for storing backups. In theory, you could use a USB hard disk, but, because it must be connected to Raspberry Pi through a powered USB hub, this approach would make the setup unwieldy.

Going the Software Route

The easiest way to transform Raspberry Pi into a backup device is to use the excellent gPhoto2 [1] software available in the Raspbian software repository. To install it, you use the
