Disasters happen every day...its a fact! • Disasters cost money so why suffer by being unprepared? • Organizations that survive typically have: • management foresight • tested procedures • processes • back-up facilities • Business Continuity Planning (BCP)

Business Continuity Planning vs.Disaster Recovery Planning • Both are directed at recovery of operations • Business Continuity Planning is directed at the recovery and resumption of business activities across the entire enterprise • Disaster Recovery Planning is usually directed at the recovery of information technology systems and business applications, including corporate data • BCP addresses Processes, People and Property
Business Continuity Planning Phases • Typically three phases • Pre-Planning • Planning • Post-Planning • Critical success factor • Cost is always an issue • Executive ownership is critical • Must be a business priority
Phase One: Pre-Planning • Project initiation and management • Establish a need • Executive management ownership • Time and budget allocation • Risk evaluation and control • Events and environment issues • Facilities and process evaluation • Cost benefit analysis • Impact analysis • Disruption and disaster scenarios • Critical business functions • Recovery time analysis
Phase Two: Planning • Develop continuity strategies • Alternative organizational recovery • Operations and information systems • Adhere to recovery time objectives • Emergency response and operations • Procedures for response and stabilization • Establish operations center • Emergency command and control • Developing and implementing the plan • Plan provides recovery within time objective
Phase Three: Post-Planning • Awareness and training • Create organizational awareness • Enhance skills • Maintaining and exercising • Coordinate plan exercises • Evaluate and document exercise results • Develop process to maintain the plan • Report results clearly and concisely • Coordination and communication • Communication with media, families, suppliers • Crisis coordination with first responders, local authorities

Clients Load Balancer Web Cache Application Server Tier Java Clusters Database Tier Only as Good as the Weakest Link
BC/DR Must Address Every Component • Network Infrastructure • Data Storage – online, near-line and off-line • Application servers and their offspring Any component down = the entire system is un-usable
Network Infrastructure • Wide Area Traffic Manager to direct client traffic to proper site • Network load balancer to distribute incoming requests • Dedicated, fast link between sites • Influences production database performance • Redundant components and paths • Network paths to the site and within the site
BC/DR Techniques for Data Storage • Snapshots – frequent, within an array, FC, temporary • Mirrors – frequent, in a different array, FC, temporary • Replicas – synchronous or async, remote or local, FC or IP, temporary or semi-permanent • Near-Line Disk – infrequent, x-platform, FC or IP, BI copy, DLM, or staging for backup • Tape Backup – infrequent, FC or IP, required best practice for DR
Application Availability with Local Clustering Server 2 Instance ‘B’ Server 1 Instance ‘A’ Database Protects from local server failures Depends on shared available storage

Key Steps to Success • Conduct a Business Impact Analysis • Identify which processes are truly critical and cost of BC • Prioritize investments in people and technology • Plan and Implement • Test, test, test!!! • Review the business continuity plan when the business process changes
Real Life Example Ohio Dept. of Public Safety • State Highway Patrol • Bureau of Motor Vehicles • Emergency Management Agency • Emergency Medical Services • Investigative Unit • Homeland Security • Administration
Data Center Facilities • State of Ohio Computer Center – • West campus of Ohio State University • Primary site • Full data center facilities, i.e., UPS, Generator, Environmental • Operates light out • Charles D. Shipley Building – Public Safety Headquarters, 1970 W. Broad Street • Approximately 4 miles apart • Secondary site • Full data center facilities, i.e., UPS, Generator, Environmental • Remote operations
Features • OC48 Sonet ring between the buildings • Moving to Gigabit Ethernet • Mainframe environment has mirrored disks at primary site, 3rd mirrored leg at secondary site • Robotic tape silos at primary site, remote tape drives at secondary site • Redundant server with failover for law enforcement • Servers at either site, mirror to other site
Decision Factors • Prioritize business functions • Work with business units for business continuity to determine IT disaster planning levels • Determine level of acceptable risks • Distance for secondary site • Hot versus cold site • Mirror data versus backups • Redundant servers with failover versus build new server at time of disaster
