No matter how much we might try to protect our network from it the fact is there life will happen to it some things are going to go wrong so in this chapter we are going to discuss managing disaster recovery. In particular we are going to talk about what disaster recovery is and then the parts of disaster recovery plans. So what is disaster recovery? First of all what is a disaster? A disaster as defined by network administrator is a certain catastrophic loss of data and or functionality, because the network relies on those resources. Now a disaster could be a national disaster, it could be a tornado or it could be a flood or, it could be a hurricane, it could be a power outage. But a disaster could also be that somebody pushes the wrong button at the wrong time so a disaster is whenever we have a sudden catastrophic loss of data and of functionality and it affects the users. So what is disaster recovery? Well, disaster recovery is the ability to bring the system backup to a functioning state and to restore the data. Both of those are involved in disaster recovery because just bringing the system back up to functioning state is not going to do it, if we have lost the data that was in the system. The data that we need is the data that is irreplaceable information that people have created. That is irreplaceable. We will talk about how we protect that data. Other data that we need is the data that we should use to configure the system. Because we can't get the system backup to optimal functioning if we don't have the configuration data. So we got to be able to bring the system backup to where it was before. Which means that we have to have the ability to bring back anything that was lost that had to do, well, how the components of the system work together, the configuration data. Configuration data is extremely important as well as any data that the users were using. So we are going to discuss both bringing back the data that the users use on day to day basis that they created, And that they certainly don't want to lose and also then bringing back the capability of the system to function as it was before the disaster. So part of that the big part of that is regular backups. We will talk about the parts of the disaster recovery plans and how they all work together in our next section.
