7.3. DFS Replication
DFS Replication is the new state-based, multimaster replication engine in
Windows Server 2003 R2. Although some DFS Replication concepts and
processes are similar to the concepts and processes in File Replication
service (FRS), there are several important differences that you should be
aware of before you deploy DFS Replication.
7.3.1. DFS Replication Concept
First, let’s review the basic concepts of DFS Replication. These concepts—
replication groups, connections, members, and replicated folders—are
illustrated in the following figure.
As this figure shows, a replication group is a set of servers, known as
members, that participates in the replication of one or more replicated
folders. A replicated folder is a folder that is kept synchronized on each
member. In the previous figure, there are two replicated folders, Projects and
Proposals. As data changes in each replicated folder, the changes are
replicated across connections between the members. The connections
between all members form the replication topology.
Creating multiple replicated folders in a single replication group simplifies the
process of deploying replicated folders, because the topology, schedule, and
bandwidth throttling for the replication group are applied to each replicated
folder. To deploy additional replicated folders, you can use a short wizard to
define the local path and permissions for the new replicated folder. Each
replicated folder also has its own settings, such as file and subfolder filters,
so that you can filter out different files and subfolders for each replicated
folder.
The replicated folders stored on each member can be located on different
volumes in the member, and the replicated folders do not need to be shared
folders or part of a namespace, though the DFS Management snap-in makes
it easy to share replicated folders and optionally publish them in an existing
namespace. You will do both in one of the tasks later in this guide.
