Yeah, I have 40Mbps uploads at my house, that's the best I can get. I create anywhere from 100GB to 3TB of footage per week. On the high end, it'd take an entire week to sync, sucking up all of my upload bandwidth for that time, meaning I wouldn't even be able to upload the videos I create to YouTube/PeerTube in a reasonable amount of time. When I get faster upload speeds I'll definitely have to build a remote NAS for closer to real time backups.
