SIOS’s SteelEye DataKeeper Cluster Edition is a replication engine which enables real-time replication of running Hyper-V VMs and integrates with Windows 2008 Server Failover Clustering to facilitate high availability and disaster recovery solutions of Hyper-V resources without the need for shared storage, thereby eliminating the single point of failure that shared storage represents.
Non-intrusive disaster recovery testing for Hyper-V virtual machines.
One of the most compelling uses for DataKeeper is when it is used to replicate entire Hyper-V virtual machines (VM) in real time for disaster-recovery purposes. DataKeeper not only helps you achieve the best recovery point objective (RPO), but it also allows very simple and non-intrusive disaster recovery tests. By simply unlocking the target, the replicated VM can be started and verified to be operational while the original production VM remains online. This means you no longer have to schedule after-hours disaster recovery tests — you can do them at a moment's notice, during the middle of the day, with zero production downtime.
