What do you use for personal, offsite backup?
appl3star: Dropbox. Well, it´s an online and offline solution for me and my most valuable files no a Macbook Pro - since I get online access via getdropbox.com and I got an old PC (yes, a Windows XP PC) as a sync client for Dropbox on a second location. So if both machines fail: Online copy. And if Dropbox fails, I still got everything on two harddisks in separate locations.
