I do offsite backup with 30Mbps up, it takes days to do the initial but incrementals are fine.

Whenever I do an initial, I get a nastygram from my ISP (Cox Las Vegas) threatening me with disconnection for having the audacity to upload 3TB in a few days. This happens despite having paid an extra $50(!) line item addon (on top of a $120/mo bill, so a 42% upcharge) for “unlimited transfer” every month for something like four years.

Criminal scum, the lot of them.
