I'm looking for some suggestions on good ways to back up my files. I just moved from a Dell to my 1st mac (a MacBook Air 13 with 128gb). My current dell probably has 20gb or so of pictures and another 90gb of music and then a smaller amount of videos and random files. It's not important that all of this lives on my mac (and it can't) but I was trying to find an easy solution for juggling external drives, flash drives, sdxc cards etc. I could probably portion out music that I really want and listen to a lot and pictures from the last few years to keep locally and those that I don't need on another device. Does anyone have experience with a similar situation? What are your thoughts on sdxc cards or the really small flash drives that are barely noticeable when plugged in? Any help would be appreciated. Thanks!
