Windows 8.1 and Windows Server 2012 R2 include new functionality for virtual machine replication and failover recovery.
Msvm_ReplicationProvider class
The ChangeReplicationModeToPrimary, GetReplicationStatisticsEx, InitiateFailback, RemoveReplicationRelationshipEx, and ResetReplicationStatisticsEx methods have been added to the Msvm_ReplicationService class. The GetReplicationStatisticsEx, RemoveReplicationRelationshipEx, and ResetReplicationStatisticsEx methods replace the GetReplicationStatistics, RemoveReplicationRelationship, and ResetReplicationStatistics methods.
The Msvm_SystemReplicationRelationship class shows an association between a virtual machine and many replication relationship.
The AdditionalSettings and ReplicationProvider properties have been added to the Msvm_ReplicationSettingData class.
Info about host-to-host provider has been added to the CreateReplicationRelationship and ModifyReplicationSettings methods of the Msvm_ReplicationService class.
The RequestReplicationStateChangeEx method has been added to the Msvm_ComputerSystem class and replaces the RequestReplicationStateChange method. The InstanceID property can now indicate extended replication. For more info about extended replication, see Msvm_ReplicationRelationship.
Msvm_ReplicationSettingData and Msvm_ReplicationRelationship instances have a 1:1 relationship that you can represent with a Msvm_SettingsDefineState association.
Msvm_SettingsDefineState property name Value ManagedElement Represents the Msvm_ReplicationRelationship object SettingData Represents the associated Msvm_ReplicationSettingData object Msvm_ReplicationSettingData can differentiate between setting instances for replication relationship based on the InstanceId or ReplicationRelationship property. Therefore, these methods that deal with single relationship didn't change their signature:
Although you can use GetReplicationStatistics, RemoveReplicationRelationship, and RequestReplicationStateChange always for the primary relationship, we recommend that you instead use GetReplicationStatisticsEx, RemoveReplicationRelationshipEx, and RequestReplicationStateChangeEx because they can process primary and extended replication relationship. For more info about extended replication, see Msvm_ReplicationRelationship.
Although these properties of the Msvm_ComputerSystem class continue to indicate the status for primary replication relationship, instead use these properties of a Msvm_ReplicationRelationship object to determine the current status for primary and extended replication relationship.
Property name Type ReplicationState Uint16 (RO) ReplicationHealth Uint16 (RO) LastReplicationTime DateTime FailedOverReplicationType Uint16 LastApplicationConsistentReplicationTime DateTime LastReplicationType Uint16
