5 DR/BC Challenges For Applications Ensuring Application Availability Given Massive Data Growth Budget Pressures Meeting Stricter Regulatory And Competitive Requirements For Retention, Security And Protection And Doing So In Today s Cloud World New Choices, New Benefits But New Challenges Too 5

6 European Disaster Recovery Research Data Today Gone Tomorrow 74% 54% 40% 80% Not Very Confident That They Can Fully Recover After A Disaster Have Lost Data And/Or Suffered Systems Downtime In The Last Year Still Use Tape For Recovery...And Of Those Still Using Tape Want To Move To Disk-based Backup 6

7 What we define as a disaster? Fire Floods Tornados Tsunami Earthquakes 7

8 What we define as a disaster? Hardware failures Sabotage Human Errors 8

9 Application Availability Challenges Prepare For Much More Than Just Disaster Recovery Events That Require A Data Center Failover: <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, Batch Jobs Data Warehouse Extracts, Builds, And Loads Gartner Group, November

10 Business Continuity and Disaster Recovery Decision Drivers Business Considerations Cost Technical Considerations Consistency and Recovery Functionality, Availability Recovery Time Objectives Capacity Bandwidth Recovery Point Objectives PRIMARY DECISION DRIVERS Performance 10

11 Business Continuity Considerations Answer these questions with the right solution to mitigate these risks 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? 11

12 What s Your RPO / RTO Per Application? Recovery Point Objectives Recovery Time Objectives 5 a.m. 6 a.m. 7 a.m. 8 a.m. 9 a.m. 10 a.m. 11 a.m. 12 a.m. 1 p.m. 2 p.m. 3 p.m. 4 p.m. 5 p.m. 6 p.m. 7 p.m. RPO: Amount Of Data Lost From Failure, Measured As The Amount Of Time From A Disaster Event DECLARE DISASTER 10 a.m. RTO: Targeted Amount Of Time To Restart A Business Service After A Disaster Event Protecting Information Is a Business Decision 12

13 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 13

14 Disaster Avoidance Application continues with no disruption (Zero Downtime) High Availability Application restart with limited disruption Disaster Recovery Backup and Offsite Replication 14

15 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

16 DR/BC Studies and Lessons People Learned 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 16

17 It s a Question of Methodology Methodology Disaster Recovery Business Continuity Disaster Avoidance Strategy Backup, Transport, Restore, and Recover Synchronize and Restart Failover and Failback Principal of Operations Tape based Processes Unit of Recovery Unit of Recovery Underlying Technology Tape, B2D, VTL, 3D, IP Replication Replication and Consistency Groups Replication, Enterprise Consistency Groups, and Scripting Engines RTO Hours to Days Minutes to Hours Minutes to 0 RPO Hours to Days Zero, seconds, minutes, hours 0 to Seconds Services EMC Solutions Services Backup to Disk, Networker, Data Domain, Avamar Services SRDF, MirrorView, RecoverPoint, SanCopy, Open Replicator VMWare Site Recovery Manager (SRM) with EMC Replication STAR, GDDR VPLEX, RecoverPoint 17
