To use DFS Replication, you must create replication groups and add replicated folders to the groups. Replication groups, replicated folders, and members are illustrated in the following figure. This figure shows that a replication group is a set of servers, known as members, which participate in the replication of one or more replicated folders.
A replicated folder is a folder that stays synchronized on each member. In the figure, there are two replicated folders: Projects and Proposals. As the data changes in each replicated folder, the changes are replicated across connections between the members of the replication group. 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 Dfsradmin. This action is one of the two delegation actions that are available in DFS Management. To manually perform this action in Active Directory Users and Computers, follow these steps:.
Click the Security tab, and then click Advanced. Grant the desired users or groups the Create All Child objects permission, and then click to select This object only in the Apply onto area. This is the other delegation action that is available in DFS Management. Grant the desired users or groups the Full Control permission, and then click to select This object and all child objects in the Apply onto area.
Typically, the user must be an administrator to manage local computer settings. To enable a user who is not an administrator to manage local computer settings, grant the user direct control of the required objects in Active Directory.
To do this, follow these steps:. Right-click the computer node, and then click Properties. By default, the path of the computer node is one of the following:. To grant a user control of all existing and future replication groups in a domain, follow these steps:. Add the users or groups to each member's local Administrators group. Or, grant the Full Control permission for the computer objects of each server in the replication groups. To grant a user rights only to modify, to add, or to delete a replicated folder, follow these steps:.
To grant a user rights only to modify, to add, or to delete members and connections, follow these steps:. To generate a diagnostic report, a user must be a local administrator of the servers that are part of the report. More Information Configuration objects It is useful to have an overview of all objects before you view each object in detail. A green check mark verifies that everything is working properly and that the node is online, whereas a red X means that there is a problem.
To add a new link, right click the root for which you want the link to be created, and select New Link. In the "New Link" screen, enter a name and path for the link and click OK. Repeat this for as many links as you need to create. Figure 5: creating a new link. Links are visible right under the node. Figure 6: dfs root and three links in the DFS mmc console. Publishing the root in Active Directory By publishing dfs roots in AD as volume objects, network users will be able to search for shares more easily and administration can be delegated.
To do this right click the desired dfs root, select Properties and go to the Publish tab. Enter the appropriate details in each box and press OK. In the keywords section you can specify certain words that will help locate the dfs root when it is being searched for. Figure 7: publish tab in the dfs properties window. The four ways in which replication can be achieved between two or more servers are: - Ring - Hub and Spoke - Mesh - Custom The first three refer to network topologies and the last allows you to specify an advanced method of replication, which can be tuned to your needs.
The advantages and disadvantages of replication are as follows: Advantages - client caching, integration with IIS, easy to administer and setup. Disadvantages - limited configuration options, there is no method of programmatically initiating a replication session. We have seen how with the use of the Windows Distributed File System, one is able to manage data more efficiently. The new and improved features make data management and distribution faster and more effecient because users are able to find what they need when they need it.
