I’ve not weighed up R2’s storage cost per gb vs Backblaze yet so it is something I will look into, but currently Backblaze offer free egress up to 3x our monthly storage. We’re only storing about 190gb, so we can transfer over 550gb comfortably for free per month. Currently we transfer on average about 300gb from Backblaze so we’re not being charged for it.

There is also the possibility of getting totally free egress, but its been a while since I looked at that, and relies on the Pictrs dev changing something in the Pictrs software, if I am remembering correctly.
