Long story short, I think its time I need a fresh install of OS X. I want to do a back up of my HDD but don't know which route to go? Should I use Time Machine or Carbon Copy Cloner. I want to start completely fresh just transfer over my files and no OS/Apps etc. Which is the better route to take? I'm leaning towards Carbon Copy only because I can have a bootable drive if something goes wrong. However, once the back up is made can I just drag and drop my files again? I'm mostly concerned about my iTunes and photos/lightroom/aperture libraries and playlist/folders? For instance if I copy of the iTunes Music Library.xml file it should recreate my library as it was, correct?
