Most 'X' as a service concepts have a point where doing it yourself is the more cost efficient option. Backup is no exception to that rule. A service like this works best when you have a manageable amount of very precious data. If you have mountains of low grade data then likely you're better off rolling your own. After all, since tarsnap is a very nice layer on top of S3 there is always at least one competitor cheaper for bulk back-up (amazon) and even they charge a substantial amount of money for storage and bandwidth. Costs vs benefits. It's never been different and it never will be.
