Disaster Recovery with Hyper-V Replica
Are you using Hyper-V as your Hypervisor?
You're in luck! Since Window Server 2012 R2, Hyper-V have had possibly the best disaster recovery capability built-in at no additional cost. It is called Hyper-V Replica .
To mitigate a rack failure:
Replicate the VMs from one rack to another using the 30 seconds Recovery Point Objective (RPO).
To mitigate the site failure:
Replicate from this to another physical location using either the 5 minute or 15 minute RPO. The choice of 5 or 15 minutes RPO is entirely up to you. However, you cannot use 30 seconds as the 1st replication is already using it.

- Any Network vendor
- Any Storagevendor
- Also unlimited replication is available out of the box
Some people are initially confused about when to use Hyper-V Replica and when to use Hyper-V live migration. The former, keeps up-to-date copies of your virtual machines in case of a disaster, and allows you to switch to those copies when required. This is usually an unplanned event.
However, for the latter, live migration is about planned events; moving your virtual machines and their associated storage across different locations when required.
Hyper-V Replica provides virtual machine replication for any of your servers, networks or storage vendors. It does not require a failover cluster or any shared storage. You can replicate individual or multiple virtual machines
You can replicate your virtual machines from one computer running Hyper-V at a primary site (the primary server) to another computer running Hyper-V at a Replica site (the Replika server). Keep in mind that your Replica server can accept incoming replication traffic from one or more primary server.

Hyper-V Replica Benefits
Hyper-V Replica allows you, in the event of a failure at a primary site (for example, fire, power, outage, orserver failure), to fail over your production workloads to Replica servers at a secondary location with minimal downtime.
Configurations for the Hyper-V Replica server and storage hardware at each site do not have to be identical. Domain membership is also not required.
Hyper-V Replica provides the option to restore virtualized workloads to a point in time, depending on the recovery histroy selections for the virtual machine.
Hyper-V Replica provides the necessary management APIs that enable IT management vendors to build an enterprise disaster recovery solution for their customers.
Hyper-V Replica enables Infrastructure as a Service (Iaas) for hosting providers that host decdicated virtual servers for their customers.
