Hey guys, today i tried the developer preview of Mavericks and it was awesome. Unfortunately it messed up my Windows 7 bootcamp, probably becaused i repartitioned the hard drive to install Mavericks to an extra partition. I've used it for an hour and i was impressed moslty disregarding a few bugs (the battery icon showed 10 hours remaining when on 92% whereas before it was on about 5!). Now i would like to install it over my Mountain Lion and use it as a main OS but i'm not sure how to backup my data as i don't have an exeternal hard. Is there a way to back it up on to a bootcamp partition? I mostly care about pictures, music, photos, documents etc, and i only want to install it over my Mountain Lion erasing everything so it can work better. Tnx in advance.
