The CLUSCTL_RESOURCE_ADD_REGISTRY_CHECKPOINT_64BIT resource control code associates registry data, as specified in section 184.108.40.206.1.1, from the 64-bit version of the registry of the server with the designated resource.
After successful completion of the method, the server SHOULD NOT write any data to the buffer that is designated by lpOutBuffer.
The server MUST restore the registry data on the node hosting the resource prior to bringing the resource online. The server MAY choose to detect changes in the registry data and take another checkpoint of the data associated with the resource. The server SHOULD monitor changes in the checkpointed registry key and take another checkpoint when a change has been detected.
The server SHOULD<121> support this control.
