Uhh, he did say 8TB worth of data. Not knowing his internet connection, this is still pretty much out of reach for most residential services except extreme FIOS connections. If you factor in caps it could take a long time. For example, lets be generous and figure he has a 350G/mo cap. Even at this rate for 8 terabyes it would take nearly 2 full years to get it to the cloud without exceeding the cap. That's just for the upload. Same amount of time for the download. Now let's also say he didn't have a cap, and also had a great connection at about 50Mbps (which most of us don't in the US). That would take over 16 days full line rate accounting for overhead just to get it up there, same amount back down. If you had an unmetered Gigabit line, that might be one thing.
Sounds like he's a starving artist with low budget. Gotta work with the requirements.
I think sneakernet an array to a friend that you trust that lives far enough away from you or take them to work (if you don't work at home) are the best options.
