Hyper-V Replica

Asynchronous Hyper-V VM replication from a primary host to a replica host for disaster recovery.

Definition

Replication frequency can be 30 seconds, 5 minutes or 15 minutes, with optional additional recovery points and extended replication to a third site. Clusters use the Hyper-V Replica Broker role.

Example

A planned failover moves a VM to the DR site with zero data loss after replicating final changes.

Exam tip

Hyper-V Replica is asynchronous, so unplanned failover can lose changes since the last cycle.
