i think it depends on how you restore it. ive never used nero, unfortunatley, but i think that if you make a full back up it will usual do all, as far as i know. the backups ive done were everything. but i think there is an option to back up just files, well, there usually is, as i kno. as nikeus asked, was it the whole thing, or just the basic files, system essential items, etc.?
