Disaster recovery (DR) involves a set of policies, tools and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. Disaster recovery focuses on the IT or technology systems supporting critical business functions,[1] as opposed to business continuity, which involves keeping all essential aspects of a business functioning despite significant disruptive events. Disaster recovery can therefore be considered as a subset of business continuity
VMware Site Recovery Manager (SRM) is a disaster recovery and business continuity solution from the VMware, which automates the transfer of virtual machines to a local or remote recovery site. SRM works perfectly with the existing vSphere software and it operates as an extension of vCenter server. SRM automates the recovery or migration of virtual machines between protected site and a recovery site.
Protected site is nothing but your primary site where active production workloads are running and recovery site is the datacenter location where you want to move your production workloads in case of Disaster like natural calamities in your primary datacenter. Virtual machines are moved to recover from a disaster or as a planned migration. vCenter Site Recovery Manager facilitates the clean shutdown of virtual machines at the protected site for a planned migration.
