Windows Server Backup - error 0x81000101

WindowsQ: Windows Server Backup keeps saying it has failed to backup. It gives me this error 0x81000101. What does this mean and why?

A: Sometimes Windows Server Backup failed to backup the data. Windows Server Backup is timing out during shadow copy creation since it is taking more than 10 minutes. Here is the resolution:

  1. Run regedit.exe and navigate to
    HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionSPP”.

  2. Create a new Registry Value of type DWORD with name “CreateTimeout”.

  3. Change value to 12000000(2*10*60*1000 = 20 mins) in decimal
