@kytta consider the transfer costs. Last time I checked *data storage* costs were small at B2, but *data transfer* costs were substantial.
In a situation where something goes wrong and you need to rely on these backups, that amounts to highway robbery. And you pretty much have no choice but to pay at that point.
@rysiek they have a free allowance of 3x the stored data, and $10/TB after that. I find that pricing quite fair; definitely better than some other cloud providers
