In addition to raising prices, please implement recurring payments as soon as reasonably practical. This is what happens when one's pre-paid Tarsnap balance goes to zero: 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. I was N days from hitting a the 7 day warning, so 14+N days away from hitting "Lose all my business' backups for the last several years." It is possible that I would have gotten really lucky and seen those emails (which I was, by definition, not particularly expecting) rather than, oh, being on a business trip in April and finding about them after the fact. I cannot put enough underlines under I Would Consider Losing All My Backups A Failure Mode.
