You failed to understand that the majority of the cost to roll out the NBN is installing the fibre cables to every house. Once the fibre is in place upgrading the line cards is a negligable cost and will be paid for by subscriber fees. If you look at any decent telco they already practice this procedure (going from dial-up equipment to ADSL to ADSL2 to ADSL2+ back end equipment and many ittereation in between). The limiting part of the network is now the copper cable which needs to be upgraded to fibre.
There is something else you're forgetting. Remeber the Distribute.IT hack back in June 2011? They couldn't recover their data mostly because they used an online disk array which the hackers also took out. So even if your disk array is in a geographically separate location it's more than likely going to be connected via some method 24/7 which would make it a lot easier to take out of commision should someone want to. I know there are measures you can take, but nowhere near as strong as having offline backup/archive.
