I'm currently backing up my pi by creating an img. This produces a 16gb card and can be quite slow. I've found some code http://raspberrypi.stackexchange.com/qu ... -of-itself at the bottom of the thread.
Now I'm a bit of a noob with *nix commands and understanding partitions etc. could someone smarter than me turn goldilocks suggestion into a script I could run as a corn job
Thanks in advance
