DFSReplicationGroupConnection

Parameters

Parameter	Attribute	DataType	Description	Allowed Values
GroupName	Key	String	The name of the DFS Replication Group.
SourceComputerName	Key	String	The name of the Replication Group source computer for the connection. This can be specified using either the ComputerName or FQDN name for the member. If an FQDN name is used and the DomainName parameter is set, the FQDN domain name must match.
DestinationComputerName	Key	String	The name of the Replication Group destination computer for the connection. This can be specified using either the ComputerName or FQDN name for the member. If an FQDN name is used and the DomainName parameter is set, the FQDN domain name must match.

Description	Write	String	A description for the DFS Replication Group connection.
EnsureEnabled	Write	String	Ensures that connection is either Enabled or Disabled.	Enabled, Disabled
EnsureRDCEnabled	Write	String	Ensures remote differential compression is Enabled or Disabled.	Enabled, Disabled
EnsureCrossFileRDCEnabled	Write	String	Ensures cross-file similarity remote differential compression is Enabled or Disabled.	Enabled, Disabled
MinimumRDCFileSizeInKB	Write	UInt32	The file size threshold for RDC to apply in KB.

Description

This resource is used to create, edit and remove DFS Replication Group connections. This resource should ONLY be used if the Topology parameter in the Resource Group is set to Manual.

Examples

Example 1

Create a DFS Replication Group called Public containing two members, FileServer1 and FileServer2. The Replication Group contains a single folder called Software. A description will be set on the Software folder and it will be set to exclude the directory Temp from replication. The resource group topology is left set to 'Manual' so that the replication group connections can be defined.

Example 2

Create a Hub and Spoke style DFS Replication Group called WebSite containing one Hub member and one or more Spoke members. The name of the Hub computer is passed in the HubComputerName parameter and defaults to 'Hub'. The Hub member contains a folder called WebSiteFiles with the path 'd:\inetpub\wwwroot\WebSiteFiles'. This path is replicated to all members of the SpokeComputerName parameter array into the 'd:\inetpub\wwwroot\WebSiteFiles' folder. The spoke computers are passed in the SpokeComputerName parameter and defaults to 'Spoke1', 'Spoke2' and 'Spoke3'.
