Take a look at this similar question over on the TechNet forums


The key there is to look for the logs

Do they tell you more about the cause?

I will try as soon as server is not busy and will update.

Error in backup of C:\ during read: Error [0x80070057] The parameter is incorrect.

I just tryed again and got the following error. This failure happening at 99%. I could not find useful info on the link that you have given above post. There is a registry key whihc is not exist in my server's registry.
