Description

The Set-VMReplication cmdlet modifies the replication settings of a virtual machine.

Examples

Example 1

PS C:\>  Set-VMReplication VM01 -AutoResynchronizedDisabled $true -AutoResynchronizeIntervalStart "18:30:00" -AutoResynchronizeIntervalEnd "06:00:00"

This example configures the auto-resynchronization of virtual machine VM01.

Example 2

PS C:\>  Set-VMReplication VM01 -AsReplica -AllowedPrimaryServer server01.domain01.contoso.com

This example configures virtual machine VM01 as a Replica virtual machine, allowing replication from primary server server01 from domain domain01.contoso.com.

Example 3

PS C:\>  Set-VMReplication VM01 -RecoveryHistory 4 -VSSSnapshotFrequency 4

This example configures the recovery history and application-consistent recovery points of the virtual machine VM01.

Example 4

PS C:\>  Set-VMReplication VM01 -Reverse

This example reverses the replication of virtual machine VM01.

Example 5

PS C:\>  Set-VMReplication * server01.domain01.contoso.com 80

This example configures replication for all virtual machines on the local Hyper-V host to Replica server server01.domain01.contoso.com and port 80.

Example 6

PS C:\> $VHDS = @("C:\VHDS\vhd1", "C:\VHDS\vhd2")
PS C:\> Set-VMReplication -VMName "VM01" -ReplicatedDiskPaths $VHDS

The first command assigns the paths of the virtual hard disks vhd1 and vhd2 to the $VHDS variable.

The second command specifies the two disks in $VHDS to be a part of the included disk set for replication of virtual machine VM01.

Parameters

-AllowedPrimaryServer

When you use the AsReplica parameter to specify a virtual machine as a Replica virtual machine, this parameter determines which primary servers can send replication to the Replica virtual machine. Replication is accepted only from the server specified in the chosen authentication entry, or any other authentication entry that has the same trust group.

Type:	String
Aliases:	AllowedPS
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-AsJob

Runs the cmdlet as a background job.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AsReplica

Specifies that the virtual machine is a replica virtual machine, enabling it to be used as the source for the initial replication of the primary virtual machine.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AuthenticationType

Specifies the authentication type to use for virtual machine replication, either Kerberos or Certificate. The specified Replica server must support the chosen authentication type. Run the Get-VMReplicationServer cmdlet to verify the authentication configured for the specified Replica server, or contact the administrator of the specified Replica server.

Type:	ReplicationAuthenticationType
Aliases:	AuthType
Accepted values:	Kerberos, Certificate
Position:	3
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AutoResynchronizeEnabled

Enables replicating virtual machines that require resynchronization to be resynchronized automatically. (For example, a virtual machine requires resynchronization if the primary server shuts down abruptly). Resynchronization requires significant storage and processing resources. We recommended scheduling resynchronization during off-peak hours to reduce the impact to the host and other virtual machines running on the host. Use the AutoResynchronizeIntervalStart and AutoResynchronizeIntervalEnd parameters to specify an off-peak time to start the automatic resynchronization.

Type:	Boolean
Aliases:	AutoResync
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AutoResynchronizeIntervalEnd

Specifies the end of the time period in which you want resynchronization to start automatically.

Type:	TimeSpan
Aliases:	AutoResyncEnd
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AutoResynchronizeIntervalStart

Specifies the start of the time period in which you want resynchronization to start automatically.

Type:	TimeSpan
Aliases:	AutoResyncStart
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-BypassProxyServer

Specifies whether to bypass a proxy server while replicating data to the Replica server.

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

-CertificateThumbprint

Specifies the certificate to use for mutual authentication of the replication data. This parameter is required only when "Certificate" is specified as the type of authentication. Specify the thumbprint of a valid computer certificate from the Personal store.

The certificate must have all of the following properties to be valid:

It must not be expired.
It must include both client and server authentication extensions for extended key usage (EKU), and an associated private key.
It must terminate at a valid root certificate.
The requirement for the subject common name (CN) differs depending on whether the virtual machine belongs to a cluster. For virtual machines that do not belong to a cluster, the subject common name (CN) must be equal to, or subject alternative name (DNS Name) should contain, the FQDN of the host. For virtual machines that belong to a cluster, the subject common name (CN) must be equal to, or subject alternative name (DNS Name) must contain, the and fully-qualified domain name (FQDN) of the Hyper-V Replica Broker.

To display a list of certificates in the computer's My store and the thumbprint of each certificate, type the following:

PS C:\\\> cd cert:\LocalMachine\My

PS C:\\\> dir | format-list

For more information about certificate stores, see http://technet.microsoft.com//library/cc757138.aspx.

Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ComputerName

Specifies one or more Hyper-V hosts on which replication is to be enabled. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.

This is useful if the virtual machine runs an application that saves data across virtual hard disks (for example, one virtual hard disk dedicated for application data, and another virtual hard disk dedicated for application log files).

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

Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-RecoveryHistory

Specifies whether to store additional recovery points on the Replica virtual machine. Storing more than the most recent recovery point of the primary virtual machine allows you to recover to an earlier point in time.

-ReplicaServerPort

Specifies the port on the Replica server to use for replication traffic. Make sure you specify a port that is configured on the Replica server to support the same authentication type you specify using the AuthenticationType parameter in this cmdlet. Run the Get-VMReplicationServer cmdlet on the Replica server to check the configuration of the port, or contact the administrator of the specified Replica server.

Type:	Int32
Aliases:	ReplicaPort
Position:	2
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

Excluding a critical disk from this list could prevent the replica virtual machine from starting properly.

Type:	String[]
Position:	Named
Default value:	None

Accept pipeline input:	False
Accept wildcard characters:	False

Specifies all virtual hard disks to include for replication. This parameter can include all the VHDs attached to the virtual machine or a subset. Be sure to include virtual hard disks that are critical to the ability of the virtual machine to start, such as the guest operating system disk. Excluding a critical disk from this list could prevent the replica virtual machine from starting properly.

Type:	HardDiskDrive[]
Position:	Named
Default value:	None
