Hello First thanks for all the help the people in this forum gave me till now and can give me in this question.
I am at the moment using a Stratus Plug from Ionics, and I want to create a back up of a the software that I have installed as well as the scripts and programs I made. This back up should give me the option to flash it trought the usb port using a pen dirve and the software /root/setup/plugflasher/reflash_auto.
I was reading thins method:
