FAQ

What is disaster recovery?

Disaster recovery is the ability to recover your operations after some type of outage or disaster or some type of event that renders your operations inoperable. We subscribe to a 3DR model, or three levels of disaster recovery that you should implement.

The first is data recovery. If you have a personal disaster, if you lose a file and need to recover it, are you going to be able to do that by making sure you have the ability to recover the data first, whether it's just a simple file or applications from a server?

The second level of disaster recovery is more of a traditional or typical disaster recovery theme. In this case you might have a type of a disaster where a data center gets flooded or a whole array goes down, and you need to be able to recover all of the operations related to that, so that's a little higher of a level.

The third and highest level, what we call a doomsday level, is something like a regional disaster. An example of that is Hurricane Katrina, where it's not just affecting your data center but the entire region. How do you recover from a disaster like that?
