    • What is not a disaster?
      • Failure of an individual server
      • A short service interruption
    Power failure Server failure Disk failure Fire Hurricane Storage failure Flood Network failure Earthquake
  • 4. Requirements for Disaster Recovery Minimize Downtime 93% of companies that lost their data center for ten days or more due to a disaster filed for bankruptcy within one year of the disaster. --National Archives and Records Administration Control Cost Minimize Risk 73% of executives expressed concern with the costs associated with maintaining a secondary data centre --Beacon Technology Partners 92% of users surveyed acknowledged that their companies would face serious consequences if they had to implement their disaster recovery plans. --Dynamic Markets Ltd. Effective disaster recovery is a business imperative, but is very difficult to achieve
