Disaster recovery for Windows Server 2008 Hyper-V

The need for virtual server protection is increasing as IT organisations consolidate workloads using virtualisation software. Further magnifying this need is market research firm IDC’s recent estimate that the virtualisation market is expected to expand from $1.8 billion in 2007 to $5.3 billion in 2012, a compound annual growth rate in excess of 30 percent. As business-critical applications and data increasingly reside within virtual machines, protection against both planned and unplanned outages is a business imperative. SteelEye DataKeeper addresses these challenges and provides customers with a highly available, disaster-proof IT environment running on Windows Server 2008 Hyper-V.

DataKeeper is a highly optimised data replication solution for Windows Server 2003 and Windows Server 2008. The product is sold in two versions: DataKeeper delivers data replication services as an extension to Windows Server 2003 and Windows Server 2008 while DataKeeper Cluster Edition further extends the capabilities of Windows Server Failover Clustering. Both editions support real-time replication of Windows Server 2008 Hyper-V virtual machines between physical servers across either LAN or WAN connections.

By keeping a running Windows Server 2008 Hyper-V virtual machine in sync with a standby VM in an alternate location, DataKeeper enables disaster recovery without the data loss typically associated with traditional backup and restore technology. Real-time continuous replication of active Windows Server 2008 Hyper-V VMs helps ensure that in the event of a disaster, the standby server can be activated with minimal to no data loss.

DataKeeper Cluster Edition allows administrators to build “shared-nothing” and geographically dispersed Windows Server 2008 Hyper-V clusters. By eliminating the requirement for shared storage, the administrator can protect against both planned and unplanned downtime of servers and storage. The use of DataKeeper in tandem with Windows Server 2008 Hyper-V VMs allows for non-disruptive disaster recovery testing. By simply accessing the replicated VMs in the disaster recovery site, the administrator can segment a virtual network separate from the production network and start the replicated VMs for disaster recovery testing. Complete disaster recovery testing can be performed without impacting the production site at all.
