For the moment, my worse case scenario is if my house gets toasted, I will have near 100% data loss as I don't use off-site at the moment. While disks don't last forever, I'm suggesting you could keep up to 3 copies at very low cost. Apart from the live copy, I don't run the backups 24/7 so they're not at risk from transient conditions.
While I'm not a data centre user in quantity of disks, I'd say there is a better than 95% chance of a disk lasting 3 years at 24/7 running, without noticeable error. With two copies, that's well over 99%, and considering I don't run them 24/7, the operating life may well be longer. If I were paranoid, a 3rd copy off site would pretty much cover reasonable scenarios outside the collapse of civilisation.
