Always. ALWAYS have SEVERAL backup copies of your work!
I just found out ALL my digital artwork from years is gone for good! The hdd just decided to go belly up and my back up DVDs got lost. All my work from my graphic design years, my source files for interactive work, my all digital paintings.
I'll have to live with the low res files at fb.
