A fundamental part of protecting IT is ensuring that the services provided by virtual machines are resilient, and robust at all levels of the compute stack, from hardware through to the application. vSphere Replication is a feature introduced with VMware vSphere 5.1. It is designed to augment the recovery capabilities of the VMware vSphere platform by providing a built-in capability to continually replicate a running virtual machine to another location.
Replication creates a copy of a virtual machine that can be stored locally within a cluster or at another site, providing a data source to rapidly restore a virtual machine within minutes. vSphere Replication augments offerings in the vSphere availability protection matrix. It provides a solution that enables recovery time better than that of restoring from backup, without introducing the complexity of a complete storage array–based replication configuration.
vSphere Replication also enables configuring replication on a per–virtual machine basis and significantly rounds out the capabilities of protection offered by vSphere. This paper will help you understand what vSphere Replication is and some of the benefits of its features. It will also discuss how it works to protect your virtual machines against failure.
