Disaster Recovery & Business Continuity Overview

  1. 1. Agenda I. Overview II. DR & BC Planning III. Essentials For High Availability IV. Hardware Solutions V. Conclusion
  2. 2. Did You Know? • 60% of companies that lose their data will shut down within 6 months of the disaster. • 93% of companies that lost their data center for 10 days or more due to a disaster filed for bankruptcy within one year of the disaster. 50% of businesses that found themselves without data management for this same time period filed for bankruptcy immediately. (Source: National Archives & Records Administration in Washington) • Companies that aren’t able to resume operations within ten days (of a disaster hit) are not likely to survive. (Strategic Research Institute)
  3. 3. Did You Know? • 30% of small businesses admit they have no formal storage procedures, or do not implement their procedures consistently. (Imation’s Small Business Survey Special Report) • 55% of small businesses rated themselves as “fair” or “poor” in terms of having a documented disaster recovery plan, or do not have one at all. • Hardware or system failure accounts for 78% of all data loss - Human error accounts for 11% of all data loss - Software corruption accounts for 7% of all data loss - Natural disasters account for only 1% of all data loss.
  4. 4. Types of Disasters • Natural Disasters – Power Outages, Floods, Hurricanes, Tornadoes, or Earthquakes • Human Disasters – Hazardous Material Spills, Bio-terrorism, Human Errors • Hardware Failures – Hard Drive Meltdowns, Internet Outages, Etc.

  6. 6. What Is Disaster Recovery? • Disaster Recovery: – the process related to preparing for recovery or planning critical technology infrastructure before a natural or human disaster occurs.
  7. 7. What Is Operational Recovery? • Operational Recovery: – Like disaster recovery, this practice focuses on the recovery of applications and technology; however, in this case, the recovery is within the primary processing location. – Operational recovery contemplates the need to recover from a service disruption that does not require a disaster declaration. – Operational recoveries may be daily occurrences responding to something that is not operating to plan and needs to be fixed, for example, failure of a file server.
  8. 8. What Is High Availability? • High Availability: – In contrast to planning for recovery is planning for resiliency or uptime. – Application clustering, hardware clustering, virtualization, and local replication technologies are all used to keep an application resilient. – Basic idea is to build an architecture that can continue to operate without disruption even when one of its components fails. Resiliency is focused on “uptime” rather than recovery time.
  9. 9. What Is Business Continuity? • Business Continuity: – In contrast to planning for recovery is planning for resiliency or uptime. – Application clustering, hardware clustering, virtualization, and local replication technologies are all used to keep an application resilient. – Basic idea is to build an architecture that can continue to operate without disruption even when one of its components fails. Resiliency is focused on “uptime” rather than recovery time.
  10. 10. Disaster Recover Planning     Infrastructure Layer Storage Layer Server Layer Application Layer
  11. 11. Disaster Recover Planning Infrastructure Layer  Needs to be architected in the most resilient fashion possible  Must be built to 24 x 7 uptime  Redundant components, secondary routes, and redundant power  Develop a site that is an extension of your primary site, not a mirror or isolated copy
  12. 12. Disaster Recover Planning Storage Layer  Contains the vital data of your business  Copies of the data for local processing, copies for local restoration and local outages, & copies for disaster recovery
  13. 13. Disaster Recover Planning Server Layer • The file servers and the strategy for keeping them active and running • Three common architectural approaches: 1. 2. 3. Virtualizing the servers so the application sits on a virtual container Clustering the servers so that two or more servers are working in unison supporting an application or process Load balancing the servers to create two separate processing domains that can work in conjunction with each other and yet are maintained separately
  14. 14. Disaster Recover Planning Best Practices • Create a strategic plan – Identify and analyze disaster risks/threats – Classify your disaster risks – Build a risk assessment – Determine the effects of a disaster – Evaluate the mechanisms for recovery – Implement your recovery phases
  15. 15. Disaster Recover Phases 1. Activation Phase – Disaster effects are assessed 2. Execution Phase – – Recovery procedures executed Business operations are restored 3. Reconstitution Phase – Original system restored
  16. 16. Essentials For Ensuring Recovery & Minimum Downtime 1. 2. 3. 4. System Configurations Hardware Failover Data Storage Backups and Replication
