I have a service that allows unlimited online backup. I also have an unlimited FTTC product. So I'm currently backing up my hard drives, which amounts to hundreds of GBs of data. I've never transferred this much data in a month before and find it hard to believe that anyone at Plusnet looking at my data usage would not think I'm abusing their service. At the back of my mind is the concern that sooner or later Plusnet are going to take action against heavy users, as they've done before.
