That seems harsh. If they really are raising B2 storage prices by 20% having held them unchanged for 7 years then in my country that's not even keeping up with inflation. And if they're charging flat rates for their other system but average data volumes have increased a lot - which seems very likely - then again a transparent increase in the pricing isn't unreasonable. The last thing I'd want for a backup service is to end up quietly cutting corners because they are no longer making enough money to do things properly.
