Server 2008 r2, shadow copy number inside the registry changed beyond 64 limit set
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ VSS \ Settings]
"MaxShadowCopies"=dword: 00000200

The question now is, the shadow is able to survive, but in previous version of the show cannot exceed 64 version, above wouldn't show, please answer where to set the display limit,
