Data Storage Question!!

I’m preparing to shoot a movie in a couple weeks, and I need to be able to store up to 8 TB of footage. I’ll be shooting the movie on a bus as it travels long distances. The data needs to be backed up such that I’m positive I won’t lose it.

How can I do this cost-effectively? Should I keep a big hard drive with me on the bus and one back home that I can upload to? Is there a cheap cloud storage service that would be better than this? Is a rattling bus a dangerous place for a hard drive, and would a solid-state drive fare considerably better?

Y’all know more about computers than I do. Please come to my rescue.

In short: How should I store and back up 8 TB of footage while on the road?
