Management Context: On creating a replica site, the selected Organization (O) or Organizational Unit (OU) becomes the management context. There is no separate workflow to create a management context.
DFS Replica (VLDB): The DFS Replica (VLDB) service provides the framework for locating volumes within the management context. Managing this service involves creating, day-to-day management, maintenance, and repair of the replica. In UMC, the term VLDB is replaced with DFS Replica service for better understanding.
