Automate site recovery and migration processes to ensure fast 
and reliable RTOs. Site Recovery Manager automates the entire 
site recovery and migration process. Upon initiation of a disaster 
failover, business services are automatically recovered with no 
manual intervention. Because automation eliminates the risk 
inherent in manual processes, disaster failover can be executed 
much faster and with highly predictable RTOs. Typical recovery 
times vary between 30 minutes and a couple of hours, 
depending on the configuration.
Streamline planned migrations and preventive failovers. In 
addition to disaster recovery, Site Recovery Manager is often 
used to simplify and automate planned site migrations and 
preventive failovers. Automated failback enables quick and easy 
migration of applications from the secondary site back to the 
production site, using the original recovery plan. In addition, 
planned migration can be used when an organization knows a 
few hours ahead of time that virtual machines will be migrated. In 
this case, the planned migration workflow ensures clean 
migrations of virtual machines in an application-consistent state 
and with no data loss.
How Does Site Recovery 
Manager Work?
Site Recovery Manager integrates tightly with an underlying 
replication product, vSphere and vCenter Server to automate 
end-to-end recovery processes. Site Recovery Manager relies on 
the following components:
Replication of virtual machines to a secondary site. Site 
Recovery Manager requires an underlying replication product to 
copy virtual machine data to a secondary site. Replication can be 
provided either by built-in vSphere Replication or by a third-
party storage-based replication product. vSphere Replication 
provides cost-efficient and simple replication for smaller sites and 
Tier 2 applications. Storage-based replication is mostly used for 
business-critical environments.
Integration with replication product. Site Recovery Manager 
integrates with the underlying replication product through a 
Storage Replication Adapter (SRA). This piece of software—
written by the replication vendor—enables Site Recovery 
Manager to see which virtual machines are being replicated and 
coordinate execution of recovery plans with the replication layer.
Integration with vCenter Server. Site Recovery Manager 
requires separate vCenter Server instances at both the 
production and failover sites. Site Recovery Manager instances 
are deployed at both sites and integrate directly with their local 
vCenter Server instances.
How Is VMware Site 
Recovery Manager Used?
Traditional disaster recovery solutions often fail to meet business 
requirements because they are too expensive, complex and 
unreliable. As a result, IT departments—uncertain if the quality of 
the protection is worth its cost—hesitate to expand disaster 
protection beyond their most critical applications. The best 
disaster recovery solution should provide great protection, with 
minimum hassle, at the lowest possible cost. IT organizations use 
VMware vSphere and vCenter Site Recovery Manager to ensure 
highly reliable RTOs and RPOs at a much lower cost and level of 
complexity than traditional disaster recovery. With Site Recovery 
Manager, organizations can expand disaster protection to all 
applications that they run on the vSphere platform, and to 
smaller sites.
Organizations use Site Recovery Manager to:
Provide cost-effective and powerful replication of virtual 
machines to a secondary site. Site Recovery Manager requires 
an underlying replication product to move virtual machine data 
from the production site to the failover site. Site Recovery 
Manager includes built-in vSphere Replication for simple and 
cost-efficient replication. It also supports a broad range of third-
party storage-based replication products from VMware storage 
partners, enabling users to choose the best replication for their 
specific needs. Larger sites and business-critical applications can 
be protected using powerful storage-based replication. Smaller 
sites and Tier 2 applications benefit from the simplicity and cost-
efficiency of vSphere Replication. 
Simplify the setup of recovery and migration plans. Traditional 
recovery plans are complex to set up. They are usually captured 
in manual runbooks, which are error-prone and quickly fall out of 
sync with configuration changes. With Site Recovery Manager, 
setting up a recovery plan is simple and can be done in a matter 
of minutes, instead of the weeks required to set up traditional 
runbooks. Through an interface that is tightly integrated with 
vCenter Server, the user simply selects which virtual machines to 
protect, maps virtual machines to resources at the recovery site 
and specifies the virtual machine boot sequence. Site Recovery 
Manager automatically dramatically simplifies recovery plans by 
automatically coordinating most of the manual steps of 
traditional recovery plans.
Perform nondisruptive testing of recovery and migration 
plans. With Site Recovery Manager, recovery plans can be tested 
as frequently as required, without disrupting production systems. 
Site Recovery Manager provides a detailed report of the test 
outcomes, including the RTO achieved. With this information, 
organizations gain confidence that their disaster protection will 
meet their business objectives. Testing results can be saved  
and used to demonstrate compliance with disaster recovery 
requirements.
