Default Behavior

The Windows Backup service is a Win32 program that can be started by the Service Controller and that obeys the service control protocol. In Windows 8 it will not be started until the user starts it. When the Windows Backup service is started, it runs as localSystem in its own process of svchost.exe. If Windows Backup fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the SDRSVC service hasn't been started.

Dependencies

Windows Backup can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

Restore Default Startup Configuration of Windows Backup

Before you begin doing this, make sure that all the services on which Windows Backup depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config SDRSVC start= demand

3. Close the command window and restart the computer.

The SDRSVC service is using the SDRSVC.dll file that is located in the C:\Windows\System32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 8 installation media.
