There are good UI solutions to this problem... For example, a dialogue box that asks you to type "Yes I am sure I want to delete all my data, forever". We do things like this for internal tools at work, seems to go pretty well.

Bear in mind the specific case being discussed is for B2 buckets, not Backblaze personal backup. Anyone using the B2 interface directly I would hope could be viewed as technically competent. If they can distinguish between the two on their end, it would make sense to provide it as an option for B2 at least.

The best way to deal with 'are you really really sure' is something like send an email with a link you have to visit as confirmation as that breaks you mentally out of the 'keep confirming without thinking' cycle which we are all at least slightly prone to given the number of confirmation dialogues we all see these days.

GitLab makes you do something similar to delete a repo, but not as explicit with the message. I think you just have to type the repository name in a box (to confirm you read the instructions) and click the delete button.
