The real test of a disaster recovery plan happens after disaster strikes and you need to recover your servers. The more quickly and effectively this can be done, the more quickly you can resume business. Server virtualization offers some unique disaster recovery benefits.

 

You can back up a running virtual machine the same way you back up a single file. All the data and configuration in that virtual machine are backed up. This means that when you need to restore a virtual machine, you are restoring a small group of files rather than hundreds or thousands of files, and after restoration the virtual machine resumes running with the configuration and data it had at the moment you backed it up. Because you do not need to re-configured anything when you restore the server, all of your server applications and data are ready to use immediatly after restoring the virtual machine.

 

Virtual machines are easily portable from one physical server configuration to another. This provides benefits for disaster recovey scenarios because you can restore and run a virtual machine on a different server than the one where you created the backup.
