GdriveUnknown

I'm hitting also hitting the limits daily, as I just got gigabit fiber. I'm trying to backup 15TB in my Gdrive but I've only gotten upto 3TB so far. What would be the best way to go about this? After the backup I should be fine as I never upload more than 20GB-50GB Daily. I tried entering a upload throttling amount but that doesn't really work. I've tried upload threshold but that only goes to 10mb. I tried to enter 740GB, but it say the max is 10mb. Do I put 1440 Minutes in a day? Do I change the size of my cache? I've set that to 1TB.
