5 What we define as a disaster? Fire Floods Tornados Tsunami Earthquakes 5

6 What we define as a disaster? Hardware failures Sabotage Human Errors 6

7 Business Continuity and Disaster Recovery Decision Drivers Business Considerations Cost Functionality, Availability Recovery Time Objectives Recovery Point Objectives Technical Considerations Consistency and Recovery Capacity Bandwidth Performance PRIMARY DECISION DRIVERS 7

8 Events That Impact Information Availability Events that require a data center move: Fewer than 1% of occurrences Natural disasters Business mergers, acquisitions, or relocations Unscheduled events/failures: 15% Server, application, network, or storage failures Processing or operator errors Scheduled events/competing workloads: 85% Maintenance, migrations, backups/restores, batch jobs, new applications or upgrades Data warehouse extracts, builds, and loads 8

9 Business Continuity Considerations What are your company s most critical processes and data needs? How much data can you afford to lose? How quickly do you need to restore your critical processes? How vulnerable are your operations to disasters? Answer these questions with the right solution to mitigate these risks 9

10 Protecting Information Is a Business Decision Recovery point objective (RPO): How recent is the point in time for your recovery? Recovery time objective (RTO): How fast can you restart a failed application? (RPO+RTO = Acceptable Business Risk) RPO RTO DAYS HRS MIN SEC EVENT SEC MIN HRS DAYS TIME 10

11 Balancing Business Requirements and Cost Cost Cost of Data Availability Cost of System Availability Cost of Data Loss Cost of System Downtime Ideal Solution Set HOURS RPO Hours of Lost Transactions TIME 0 HOURS RTO Hours Required to Resume Business 11

12 Disaster Avoidance Application continues with no disruption (Zero Downtime) High Availability Application restart with limited disruption Disaster Recovery Backup and Offsite Replication 12

13 Continuity Challenge: The Common Current State Continuity Issues Survive a disaster Achieve high availability Prevent data corruption Non-disruptively upgrade software and/or hardware Do parallel processing Move and migrate data Restart the enterprise Protect remote data sites Shorten backup and restore times Adds costs Cannot add resources Overprotected Underprotected Not protected Pain Points Inconsistent service levels Gaps in coverage Different requirements Different technologies Different processes Growth in complexity and effort Growth in cost and risk to the business 13

14 Typical Service Levels by Technology RPO (Hours of lost transactions) EVENT RTO (Hours required to resume business) Tape Vaulting Daily Tape Backup Daily Disk Backup Asynchronous Disk Mirroring Synchronous Disk Mirroring Continuous Protection Active/Active Data Centers

15 BC Studies and Lessons Learned People and Information are Irreplaceable Remote Replication As a Restart Strategy works A building, a data center, a city, and a region are all single points of failure The most critical aspect in a recovery is data consistency! Managed service providers can be overwhelmed Disaster Recovery (DR) it is based on the principles of Backup, Transport, Restore, and Recover. Business Continuity (BC) BC is based on the principal of Synchronization and Restart. Disaster Avoidance (DA) / Disaster Tolerant Computing (DTC) is based on the principal of Clustering, Failover and Failback 15
