Dfs replication what is

In the console tree, under the Namespaces node, right-click a folder that has two or more folder targets, and then click Replicate Folder. Configuration changes are not applied immediately to all members except when using the Suspend-DfsReplicationGroup and Sync-DfsReplicationGroup cmdlets. The new configuration must be replicated to all domain controllers, and each member in the replication group must poll its closest domain controller to obtain the changes.

The amount of time this takes depends on the Active Directory Directory Services AD DS replication latency and the long polling interval 60 minutes on each member. To poll immediately for configuration changes, open a Command Prompt window and then type the following command once for each member of the replication group: dfsrdiag.

Click 'Next. Click 'Install' if everything looks as expected. The second configuration option allows you to configure a reference name for the path you have selected. Select 'Next. The default option is OK, and anytime an update is made on the source server the destination server is updated.

Select 'Create' if everything looks OK. Phone: Email: support percussion. Related Links. Introduction DFS replication is used to ensure that data is synchronized between servers. To setup a local publishing server in CM1: 1 Navigate to the 'Publish' menu.

The DFS namespace aggregates and abstracts this underlying complexity from the end-users. This is not only beneficial from the end-user perspective but also the IT admin who, with DFS, has greater flexibility to manage the underlying physical storage backing the DFS hosted shares. If more storage is needed, the IT admin can add a new storage device and share, copy over the files and synchronize them from the old device to the new device, and simply retarget the DFS link to point to the new share on the backend.

However, non-Windows backed shares can be published for which client redirectors are available in a DFS namespace. This can include any SMB-compatible device such as network-attached storage NAS devices from many different vendors as well as Samba shares. This is really up to the needs of the business. Common DFS organization may be related to the business organizational unit, the geographical location, combinations of both, or perhaps other custom business entities to define a DFS namespace.

We have already touched briefly on why a domain-based DFS namespace would be beneficial, however, choose domain-based DFS namespaces for the following:. DFS Replication in Windows Server is a role service that allows replicating the folders referred to by a DFS namespace path across multiple servers and sites.

DFS replication is configured as a multi-master replication technology meaning any member of the DFS replication group can make changes to the data. RDC is extremely efficient in that it can detect changes to a file and only copy the changed file blocks instead of recopying the entire file. A DFS replication group mentioned earlier is a group of servers that participates in the replication of one or more replicated folders.

A replicated folder stays synchronized between the members included in the DFS replication group. The settings for the replication group including its topology, schedule, and bandwidth throttling are applied to the replicated folders contained in the DFS replication group.

Each replicated folder in the DFS replication group has unique settings including the file and subfolder filters to filter out different files and subfolders for each replicated folder. Replicated folder can be located on different volumes in the member and do not need to be shared folders or part of a namespace. An important note to consider when looking at how DFS replication works is that DFS replicates a file only after it is closed.

This means that it is not a suitable solution for replicating files that may constantly be in use like database files or other files that are open for an extended period of time. For documents or other files that need to be worked on in parallel with other users, you may want to look into other technologies like Storage Replica that was introduced in Windows Server There are a few requirements and considerations to make note of when thinking of deploying a Distributed File System DFS.

Servers that are running the following operating systems can host multiple domain-based namespaces in addition to a single stand-alone namespace. Servers that are running the following operating systems can host a single stand-alone namespace:. DFS can be used in conjunction with Azure, but there are a few considerations that you will want to make in using the two together.

PowerShell is a great way to install DFS roles quickly and easily. This is also great for the automation and mass installation of roles across many servers.

As you can see the management console is fairly straightforward. The New Namespace Wizard launches. The first step is entering the name of the server that will host the namespace. You can either enter the server name or click Browse and find the server name. Enter the Namespace server. Enter the Namespace Name and Settings. As noted, the name you choose is the name that appears after the server or domain name in the namespace path. You can also click the Edit Settings button and get more granular with the local path and settings.

Enter the name for the namespace. The next step is choosing a Namespace Type. This is where you can choose between a domain-based and a standalone namespace server. Also, you can choose the Enable Windows Server mode enabled by default which sets up the namespace with increased scalability and access-based enumeration ABE. ABE means that end users only see the files presented which they have access to. Choosing the Namespace Type.

Reviewing DFS Namespace settings and completing the configuration. Finishing the new namespace wizard.
