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. Each replicated folder has unique settings, such as file and subfolder filters, so that you can filter out different files and subfolders for each replicated folder.

Authentication-Level Constants. There is one update manager per replicated folder. Update managers work independently of one another. By default, a maximum of 16 four in Windows Server R2 concurrent downloads are shared among all connections and replication groups. Because connections and replication group updates are not serialized, there is no specific order in which updates are received. If two schedules are opened, updates are generally received and installed from both connections at the same time.

If the schedule is open, DFS Replication will replicate changes as it notices them. There is no way to configure a quiet time for files. If you are using Windows Server or Windows Server R2, you can create a read-only replicated folder that replicates content through a one-way connection.

Doing so can cause numerous problems including health-check topology errors, staging issues, and problems with the DFS Replication database. If you are using Windows Server or Windows Server R2, you can simulate a one-way connection by performing the following actions:.

Train administrators to make changes only on the server s that you want to designate as primary servers. Then let the changes replicate to the destination servers. Configure the share permissions on the destination servers so that end users do not have Write permissions. If no changes are allowed on the branch servers, then there is nothing to replicate back, simulating a one-way connection and keeping WAN utilization low. If DFS Replication considers the files identical, it will not replicate them.

If changed files have not been replicated, DFS Replication will automatically replicate them when configured to do so. However, this is only a schedule override, and it does not force replication of unchanged or identical files. During initial replication, the primary member's files will always take precedence in the conflict resolution that occurs if the receiving members have different versions of files on the primary member.

The primary member designation is stored in Active Directory Domain Services, and the designation is cleared after the primary member is ready to replicate, but before all members of the replication group replicate. If the initial replication fails or the DFS Replication service restarts during the replication, the primary member sees the primary member designation in the local DFS Replication database and retries the initial replication.

If the primary member's DFS Replication database is lost after clearing the primary designation in Active Directory Domain Services, but before all members of the replication group complete the initial replication, all members of the replication group fail to replicate the folder because no server is designated as the primary member. For more information about initial replication, see Create a Replication Group. The primary member designation is used only during the initial replication process.

If you use the Dfsradmin command to specify a primary member for a replicated folder after replication is complete, DFS Replication does not designate the server as a primary member in Active Directory Domain Services. However, if the DFS Replication database on the server subsequently suffers irreversible corruption or data loss, the server attempts to perform an initial replication as the primary member instead of recovering its data from another member of the replication group.

Essentially, the server becomes a rogue primary server, which can cause conflicts. For this reason, specify the primary member manually only if you are certain that the initial replication has irretrievably failed. If remote differential compression RDC is enabled on the connection, inbound replication of a file larger than 64 KB that began replicating immediately prior to the schedule closing or changing to No bandwidth continues when the schedule opens or changes to something other than No bandwidth.

The replication continues from the state it was in when replication stopped. This can delay when the file is available on the receiving member. When DFS Replication detects a conflict, it uses the version of the file that was saved last. It remains there until Conflict and Deleted folder cleanup, which occurs when the Conflict and Deleted folder exceeds the configured size or DFS Replication encounters an Out of disk space error.

The Conflict and Deleted folder is not replicated, and this method of conflict resolution avoids the problem of morphed directories that was possible in FRS. This event does not require user action for the following reasons:. When a quota threshold is reached, it cleans out some of those files. There is no guarantee that conflicting files will be saved. DFS Replication does not continue to stage files outside of scheduled replication times, if the bandwidth throttling quota has been exceeded, or when connections are disabled.

DFS Replication opens files in a way that does not block users or applications from opening files in the replication folder. This method is known as "opportunistic locking.

The staging folder location is configured on the Advanced tab of the Properties dialog box for each member of a replication group. Files are staged on the sending member when the receiving member requests the file unless the file is 64 KB or smaller as shown in the following table. Files are also staged on the receiving member as they are transferred if they are less than 64 KB in size, although you can configure this setting between 16 KB and 1 MB.

If the schedule is closed, files are not staged. If any part of the file is already being transmitted, DFS Replication continues the transmission. If the file is changed before DFS Replication begins transmitting the file, then the newer version of the file is sent.

Added the Does DFS Replication continue staging files when replication is disabled by a schedule or bandwidth throttling quota, or when a connection is manually disabled?

The following are best practices for implementing file screens or quotas: The hidden DfsrPrivate folder must not be subject to quotas or file screens. Screened files must not exist in any replicated folder before screening is enabled.

No folders may exceed the quota before the quota is enabled. The reasons for this are as follows: Opening. Unlike custom DFSR replicated folders, sysvol replication is intentionally protected from any editing through its management interfaces to prevent accidents.

MSC tool, modify the following distinguished name DN value and attribute on each of the domain controllers DCs that you want to make non-authoritative:. Run the following command from an elevated command prompt on the same servers that you set as non-authoritative:. That domain controller has now done a D2 of sysvol replication.

MSC tool, modify the following DN and two attributes on the domain controller you want to make authoritative preferably the PDC Emulator, which is usually the most up-to-date for sysvol replication contents :. Modify the following DN and single attribute on all other domain controllers in that domain:. Run the following command from an elevated command prompt on the same server that you set as authoritative:.
