The Shared Protection Point Operation Failed With Windows Server Backup 0x81000101 Error

Windows Server Backup is timing out during shadow copy creation since it is taking more than 10 minutes.

Increasing the timeout value to 20 minutes usually fixes this issue.

Add a new registry entry.

  1. Run regedit.exe and navigate to L”HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionSPP”
  2. Create a new Registry value of type DWORD with name “CreateTimeout”
  3. Change value to 1200000(2*10*60*100 = 20min) in decimal not hex

Restart backup.
