Scoped snapshots enabled.

Question

Event ID: 13
Windows cannot perform an online backup of this system because scoped snapshots are enabled. To resolve this, disable scoped snapshots by creating the following registry value
on this computer:
               PATH: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\
               DWORD: ScopeSnapshots
               Value: 0
Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.
what i'm trying to figure out is why we have the same image - creating virtual machines. when you go to backup using any backup product, DPM, TSM, Netbackup, & Windows Backup - you get this error.  for some VM's this error does not display
and will complete the backup in an online state. when was "scoped snapshots enabled" on the operating system? Server 2012 R2 sp1 enterprise & 2012 Standard?
