Default Behavior

Windows Backup is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Windows Backup service is started, it logs on as localSystem and running in its own process of svchost.exe. If Windows Backup fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the SDRSVC service startup failure.

Dependencies

Windows Backup cannot be started, if the Remote Procedure Call (RPC) service won't start.

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 11 installation media.
