About Disaster recovery, failover and high availability for virtual servers
Server virtualization has become central to data center disaster recovery planning. In addition to reducing the costs for idle physical servers and reducing data center footprint, server virtualization for disaster recovery can help improve uptime as well as speed recovery point objectives and recovery time objectives. It can also help ensure better integrity for the data you retrieve. High-availability, management and failover for virtual servers are part of achieving these objectives. In this section, we provide news, cases studies and tutorials on using server virtualization for business continuity planning and best practices for creating remote disaster recovery sites. We also compare the pros and cons of backup and recovery technologies to help you decide which products will work best for your virtualized environment's backup and recovery requirements.
