I have setup my PiBot to be a WiFi Hotspot so that I can remote in to the headless beast. Given this is no easy task for me (poor typing skills, old eyes) the setup process is prone to errors when I do it.
With that in mind I would like to clone the SD card so I have a backup. I tried to use the process set out in the Pi Weekly issue 82; however, success eludes me.
This process uses a Pi Hub and the following steps to clone multiple SD cards at once:
install dcfldd < sudo apt-get install dcfldd >
sudo dcfldd if=ImageFileToBeCopied.img of=/dev/sda of=/dev/sdb of=/devsdc of=/dev/sdd
Given I only want to clone the SD card running the PiBot using a read write adapter plugged into the Pi Hub I am guessing that I would modify the code as follows:
dcfldd if=ImageFileToBeCopied.img of=/dev/sda
However, my guess did not work -- any suggestions to allow me to clone the PiBot SD card would be greatly appreciated.
