Starting in Windows Server 2008 and continuing in Windows Server 2008 R2, DFSR supports a protective mechanism called “Content Freshness”. Content Freshness is an admin-defined setting that you can set on a per-computer basis when using DFSR on Win2008 or Win2008 R2 – it doesn’t exist on Windows Server 2003 R2. The DFSR database has a record for each Replicated Folder (RF) called CONTENT_SET_RECORD. This record contains a timestamp called “LastConnected”. We store this record on a per-Replicated-Folder basis because it’s possible for a replicated folder to be current when it’s connected to other members in that replication group. At the same time, another replicated folder can be stale because its not connected with other members in its replication group. Every day, DFSR updates this timestamp to show the opportunity for replication occurred.
