Description

The Set-DfsrConnection cmdlet changes a connection between two members of a replication group.

Distributed File System (DFS) Replication connections are the logical partnerships between members in a replication group. The DFS Replication service uses the Remote Procedure Call (RPC) protocol to communicate between servers. The DFS Replication service does not support modifying connection bandwidth or schedules, which typically do not require changes.

Examples

Example 1: Change a connection between members of a replication group

PS C:\> Set-DfsrConnection -GroupName "RG24" -SourceComputerName "SRV01" -DestinationComputerName "SRV02" -DisableRDC $True -DisableCrossFileRDC $True


GroupName               : rg 1
SourceComputerName      : SRV01
DestinationComputerName : SRV02
DomainName              : corp.contoso.com
Identifier              : 8b51a050-f32d-42dc-b008-80f56754f373
Enabled                 : True
RdcEnabled              : False
CrossFileRdcEnabled     : False
Description             :
MinimumRDCFileSizeInKB  : 64
State                   : Normal

This command changes the settings of a connection between the computers named SRV01 and SRV02 in the RG24 replication group. The command specifies that the connection no longer uses Remote Differential Compression or Cross-File RDC from SRV01 to SRV02. The administrator has determined that the network that connects these servers is a high-bandwidth LAN that should replicate faster than low-bandwidth WAN connections.

Parameters

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Description

Specifies a description for the connection.

Type:	String
Position:	6
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DestinationComputerName

Specifies the name of the receiving computer. A receiving computer is also called an inboard or downstream computer.

Type:	String
Aliases:	ReceivingMember, RMem
Position:	2
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	True

-DisableConnection

Specifies that the DFS Replication service disables the connection.

You do not typically need to disable a connection. Specify this parameter to temporarily pause replication. You can also use the Suspend-DfsReplicationGroup cmdlet to halt replication between computers. You must enable a connection between the computers before the DFS Replication service can initiate replication.

Important: Specify this parameter instead of disabling a computer's membership in the replication group by using the Set-DfsrMembership cmdlet. Disabling and enabling the membership of a computer causes non-authoritative inbound replication.

Type:	Boolean
Position:	3
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DisableCrossFileRDC

Indicates that the DFS Replication service disables the cross-file similarity Remote Differential Compression (RDC) algorithm on this connection.

Cross-file RDC uses up to five existing previously replicated files on a volume to seed a new replicating file. Applying cross-file RDC over very low-bandwidth network connections with files that are very similar results in very large bandwidth savings and potentially large time savings. When you use cross-file RDC on very high-bandwidth network connections, cross-file RDC may add too much local processing time and negatively affect performance. In extremely large datasets (millions of files on a volume with a great deal of similarity), cross-file RDC may also negatively affect CPU and disk utilization. Consider disabling cross-file RDC when you replicate over LANs and very high performance WANs. This setting is only supported on Windows Server 2012 R2 and later.

Type:	Boolean
Position:	5
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DisableRDC

Indicates that the DFS Replication service creates the connection with Remote Differential Compression (RDC) disabled.

You do not typically need to specify this parameter when you use lower bandwidth, higher latency connections. Consider specifying this parameter if the connection is over a LAN or very high performance WAN connection. By default, RDC is enabled on DFS Replication connections.

Type:	Boolean
Position:	4
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DomainName

Specifies the NetBIOS name or fully qualified domain name (FQDN) for the Active Directory Domain Service (AD DS) domain that contains the replication group. If you do not specify this parameter, the cmdlet uses the domain of the current user.

Type:	String
Position:	100
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-GroupName

Specifies an array of names of replication groups. You can use a comma separated list and the wildcard character (*).

Type:	String[]
Aliases:	RG, RgName
Position:	0
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	True

-MinimumRDCFileSizeInKB

Specifies the file size threshold, in Kilobytes, for RDC to apply.

You do not typically need to specify this parameter when you use lower bandwidth/higher latency connections. Consider specifying this parameter only if the connection is over a LAN or a very high performance WAN connection. By default, any files equal to or greater than 64KB are chunked by RDC.

Type:	Int64
Position:	7
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-SourceComputerName

Specifies the name of the sending computer. A sending computer is also called an outbound or upstream computer.

Type:	String
Aliases:	SendingMember, SMem
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	True

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
