vSphere Replication in vSphere 5.1

What is vSphere Replication

vSphere Replication is a feature of the vSphere platform. It copies a virtual machine to another location, within
or between clusters, and makes that copy available for restoration through the VMware® vCenter Server™ Web-based user interface. 

vSphere Replication continues to protect the virtual machine on an ongoing basis. It replicates to the copy the
changes that are made to the virtual machine. This ensures that the virtual machine remains protected and is available for recovery without requiring restore from backup.

vSphere Replication is provided as a no-charge component of all eligible vSphere licenses, ranging from the VMware vSphere® Essentials Plus Kit through the VMware vSphere® Enterprise Plus Edition™. As with backups through VMware data protection, protecting a virtual machine is a critical function of a hypervisor platform for the datacenter.

Unified management of vSphere Replication is provided via the next-generation VMware vSphere® Web Client.
This provides a common and unified screen for all aspects of virtual datacenter management, including many aspects of protection, such as replication, backup and restore. 

My Scenario in this Demonstration is:-

How to Configure the Replication on an VM:-

1. Deploy the vSphere Replication Appliance
2. Configure the Appliance 

(a)Type https://<Replication Appliance IP/Name>:5480 and enter the root as the username and password and click  on login button

(b)Once Login you will this screen. Now from this screen you need to configure the vCenter Server info to link this appliance with vCenter Server and you can change the default password and ip address, hostname so on. Once done click on logout.

3. Login to your vSphere Web Client and then Configure the Replication on an VM. Right Click on VM --> All vSphere Replication Actions --> Configure Replication

4. Select Target Site and Click on Next

5. Select Target Datastore. You can select local or Shared Datastore and Click on Next

6. Select RPO and Guest OS Quiescing Method and Click on Next

7.  Review the Settings and and Click on Finish

8. Check the Task Status from Recent Tasks

9. Once Done from the Home Screen Click on vSphere Replication

10. Click on sites

11. Check the Replication Status from Monitor Tab. It's not yet completed

12.  The ongoing replication is by use of an agent and vSCSI filter that reside within the kernel of an ESXi 5.0 host that tracks the I/O and keeps a bitmap in memory of changed blocks and backs this with a "persistent state file" (.psf) in the home directory of the VM. The psf file contains only pointers to the changed blocks.

13. Now it in Sync 

14. Now it's Completed Successfully 

So This is how you can configure the Replication on an VM.
