Hmm... yeah I don't use an online storage site either... but could be a good idea. I just keep everything I'm "working on" on my main internal HD of my MacBook Pro (which doesn't do much traveling) and then I make backups onto my main external HD every couple of days. Then once the data is in those two places, I can breath easy. If every decide to remove it from one of those two places (which I often do actually) then I burn in to a DVD first. I have a DVD binder of all my backups labeled well. Also, that second drive (the external...) I make backups of it onto another external here and there too. I'm paranoid about losing data. But I know if I do lose anything, it will be when I least expect it. I've found external hard drives seem to be the most dangerous place for them - so if you only have ONE and you use it a lot, and I would back them up to a second and/or DVD soon!
