Great write up, I've been curious about it, but I'm not particularly bothered. I think what I'm going to end up doing is to basically tar ~/media, pipe it through GPG, and pipe it through some upload-to-glacier script. Maybe automate that once a month or something and then have tarsnap for much smaller/rapidly changing stuff. As it stands now I have 100gb in ~/media that's costing me about $1/day, so it'd be nice to reduce that.
