# What is the difference between Virtual Failover, Disaster Recovery and High Availability?

If I were deploying a Windows Server environment, what are the differences between virtual failover, disaster recovery and high availability as well as when would you utilize them?

This question came from our site for computer enthusiasts and power users.

More appropriate for SF. –  John T Sep 21 '11 at 21:24

Thanks. When you say there is an appropriate time to use each one separately, what do you mean? Also I take it that disaster recovery and high availability is not restricted to physical infrastructure. Is that correct? You mention that it is easier when explaining in the Windows context, does this mean it is different for Linux? –  PeanutsMonkey Sep 21 '11 at 22:45
