I have about 10k pictures, (close to 50GB) on my MacBook Pro, all stored in an Aperture Library.
I run time machine (on Snow Leopard if it matters), so they're backed up hourly to my time capsule, plus I burn DVDs annually. But we had a fire scare recently, and it reminded me that both the DVDs and the Capsule are in the same physical location as the laptop, making them useless if the apartment getting destroyed is the problem (rather than the drive failure I was focused on originally).
I can obviously store the DVDs in a location outside the house, but really don't want to risk a year's data, and it's too annoying to burn all those disks monthly, etc.
Is there an automatic solution that will back up this much data automatically somewhere offsite? I'm willing to pay something in theory, but the paid idisk solution on MobileMe doesn't seem scalable, and I don't trust its longevity. Ideally, I want something I don't have to run myself periodically.
