Thanks! To be honest, getting rich has never been on my list of reasons for building tarsnap -- I really just wanted good backups. But my idea of good backups is a backup service, and in order for a backup service to be sustainable it needs to make money, and in any case I couldn't afford to spend two years writing code for tarsnap without a good chance of earning some money from it later...
A reliable revenue model only increases confidence in a service such as backups. It is always good to know your backups won't disappear because the service has gone bust.
Absolutely -- and there have been more than enough examples of backup services going out of business lately to make people worry about this. This is the main reason I wrote my previous blog post: http://www.daemonology.net/blog/2009-03-09-tarsnap-reaches-p...
