Patrick notes in detail that the post is written with Colin's approval. I am not a customer of any of Patrick's services, nor am I a customer of Colin's, although perhaps I should be a customer of both. The most telling part of the post is right here, beginning with a quotation from the Tarsnap FAQ:

" >Q: What happens when my account runs out of money?

" >A: You will be sent an email when your account balance falls below 7 days worth of storage costs warning you that you should probably add more money to your account soon. If your account balance falls below zero, you will lose access to Tarsnap, an email will be sent to inform you of this, and a 7 day countdown will start; if your account balance is still below zero after 7 days, it will be deleted along with the data you have stored.

"Yes folks, Tarsnap — “backups for the truly paranoid” — will in fact rm -rf your backups if you fail to respond to two emails.

"Guess how I found out about this?"

That says it all.

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.
