You already installed the modified version from Lululla (that he called same but v02)... so you are stuck. You need to uninstall the previous one, that you removed already by hand... and install this v01.

Or, as wrote few times, you can simply use the scripts that are already in the image at /usr/bin to do the backup, check for .sh files and you will find them. You will need to had an hdd, where the nfi file backuped will be stored.
