Default Behavior

Windows Backup is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Backup service is started, it is running as localSystem in its own process of svchost.exe. If Windows Backup fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the SDRSVC service has failed to start due to the error.

Dependencies

Windows Backup cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.

Restore Default Startup Configuration for 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 %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
