Error:The shared restore point operation failed with error (0x81000101)
[System State Backup] The creation of a shadow copy has timed
out. Try this operation again.
This error occurs when the backup fails due to Windows Server Backup timing out during shadow copy creation since it is taking more than 10 minutes.
Here is how to resolve this issue:
Increase the timeout value to 20 minutes.
This involves updating a registry key. Please do this carefully.
- Run regedit.exe and navigate to L"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SPP"
- Create a new Registry value of type DWORD with name "CreateTimeout"
- Change value to 12000000(2*10*60*1000 = 20 mins) in decimal
Re-run backup.
