Back up Your Raspberry

Just a word of warning
Raspberry pi has a feature called SDCARD Copier or something like that
It just saved me.

I started experimenting with lmms, Cecilia and building Csound from sources
in there Cecilia requires a build of wxPython and it killed my fresh build of SuperCollider 3.9 and i was angry until i realized i had made a backup copy of a 16GB Sdcard as a failsafe and i popped my case open inserted it and boom, back in business

going to make one i do not touch and one for more courageous experimentation!
