FWIW, I also have the same problem (I'm a tarsnap user). I current have just shy of 2TB of GIS data (1.6TB is elevation data alone), so right now I backup everything except my GIS data. I loves me some tarsnap for the other stuff, but right now it's not a solution for this much data. This is definately a pain point of mine. Luckily, the data doesn't change often, and if I needed to restore from data loss it doesn't need to happen ASAP. So I'm thinking just saving the data to seperate hard disks and storing those in a safety deposit box will fulfill my needs. Does that sound right? Or am I missing some large dangers in this solution? (I'm pretty new to this stuff)
