using iCloud a back-up instead of a hard disc
Haven't used iCloud before. Had two Mac hard drive disasters and I lost my huge music collection and everything else and had no back-up. Still don't have a back-up because I'm restricted by Apple to Portuguese Apple sites and they don't have what I need/want.
Thinking of a workaround. If I store everything on iCloud will I be able to get it all back on a repaired Mac or a new one if needs must?
iMac, OS X El Capitan (10.11.1), 21.5–inch
