    It looks like the SQL Server doesn’t have permission to access file C:\backup.bak. I would check the permissions of the account that is assigned to the SQL Server service account.

    As part of the solution, you may want to save your backup files to somewhere other that the root of the C: drive. That might be one reason why you are having permission problems.
