Detailed Description

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

Parameters

-AsJob

Runs the cmdlet as a background job.

Default Value

none

Accept Pipeline Input?

false

Accept Wildcard Characters?

false

-AuthenticationType<ReplicationAuthenticationType>

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.

Default Value

Accept Pipeline Input?

-AutoResynchronizeEnabled<Boolean>

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.

-CertificateThumbprint<String>

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

-VSSSnapshotFrequencyHour<Int32>

Specifies the frequency, in hours, at which Volume Shadow Copy Service (VSS) performs a snapshot backup of the virtual machines. Specify this parameter only if application-consistent replication is enabled for the virtual is and the value you set for the RecoveryHistory parameter is not zero. The cmdlet sets a value of zero for this parameter if application-consistent replication is disabled. Do not specify this parameter if you are extending replication from the Replica virtual machine.
