Call me paranoid but I worry a lot about my files. I back everything to external hard drives, but seeing as my hard drives live next to my desktop I'm not protected from natural disasters and the like. I opened a free account with recently and I have to say I'm liking it. It recognizes all of my indesign project files which makes it super easy to decide what to store to the cloud and what not to. I'm not the most tech savvy guy in this forum so I'm wondering what you all are using? Any other storage platforms I should know about?
