Yes folks, Tarsnap — “backups for the truly paranoid” — will in fact rm -rf your backups if you fail to respond to two emails.
I don't think that quite says it all, because the other important factor is that you can't properly predict when the underlying conditions that would trigger those e-mails will arise. Patrick seems to have latched onto the use of picodollars as his pet hate there, but of course the real cause is the unpredictable efficiency of compression and deduplication. This problem remains even if you move to tiered dollar pricing for "up to X GB" plans.
I have multiple businesses that are definitely good candidates for using Tarsnap, but sadly that combination of unpredictability and insufficient warning/recovery mechanisms is a deal-breaker for us. No matter how great Tarsnap might be technically, from our point of view it's not offering a reliable backup with its current model, which is a shame for all concerned really. I do hope Colin will consider the various comments on this and look into fixing it.
