I'd expect energy costs of a data centre + wages to dwarf the actual HDD costs.

A half-hour support call is going to cost something like €10 - for which you need to service 5TB-months of data (ie one month of 5000GB of data at 0.2 euro-cents pays for the support cost in min. wage employees).

It's great if this is a sustainable business as I only have 1TB of data at home and probably only a third of that needs backing up. So 4TB-months of data per annum, €8 - that's much cheaper than buying a HDD myself c. £50 [currently €60] which I expect to have c. 5 years of life. Though the A in ADSL then starts getting really annoying.
