Most Comcast customers in the US have a 1T monthly cap. Their language: "After using these 2 courtesy months, if you exceed the plan you will be charged $10.00 for each 50GB of additional data provided, but charges will not exceed $200 each month, no matter how much you use." I hit 700G last month. If I had to do a full backup or restore I'd definitely go over 1T. Annoyingly, they count both ingress and egress traffic.
