yeah i usally back up everything, i mean i have backups of the project but early versions. that one night i did a install the back up was on that oc while the actual cooked project was on a portable HDD that i take to uni. Doest matter i got alot of the blueprints documented so i can always easily get back to where i was its not the difficulty im worried about its the time it will take, would take atleast a few days non stop work to get back to where i was, oh well, thanks again guys.
