You can only patent something original, that someone with the similar experience and knowledge would NOT be able to come up with easily. Therefore, it's extremely unlikely that you could patent a stored-proc to perform backups/restores/consistency checks. Also, the amount of 'prior art' in the area would likely preclude any possibility of you being able to claim originality. And then you'd have to pay a patent lawyer to convert the idea into patent language, and file with the relevant patent offices. It's an expensive, tortuous process that I'm glad Microsoft funded for my patents.

Give your proc away for free - you won't make money from it.
