The backup either to your PC or the cloud works OK. You have 2 choices :
Connect the iPhone to your PC and run iTunes, than you can backup to PC or the cloud or both.
Connect your iPhone to electricity and wi-fi connection , and backup manualy to the cloud.
What doesn't work AUTOMATICALY as it should, is cloud backup when the iPhone is charging and connected to wi-fi and the iPhone
goes into "sleep mode". The reason ? When charging and "sleep mode", the iPhone 5 disconnects from wi-fi and connects to 3G, which doesn't support cloud backup.
