A Key Differentiation Understand the difference between Disaster Recovery (DR) and Business Continuity (BC) • Disaster Recovery: Restoring IT operations following a site failure • Business Continuity: Reducing or eliminating application downtime • Disaster Avoidance: availability to predict and take actions to avoid Disaster Impact © Copyright 2013 EMC Corporation.

Protecting Information is a Business Decision Recovery-point objective (RPO): How much data can you afford to lose, can you determine a sync point Recovery-time objective (RTO): How long can you afford to idle your business and survive? Fast recovery times enable continuous business operations Slow recovery times—or data loss—translates into Business Recover Plan and procedures Technology Failover Data Lost Recovery Point Objective © Copyright 2013 EMC Corporation.

Application Consistency Which type of consistency will be required for the applications that you’re going to protect ? Crash Consistency This is the equivalent of pulling the power from a server while the applications are running, and then powering up the server again. Replication solutions that have limited knowledge of the applications are easier to put together. During recovery you are reliant on the application’s capability to start up on its own merits, or possibly with some intervention. Following a fail-over, the data will not have transactional consistence, if transactions were in-flight at the time of the failure. In most cases what occurs is that once the application or database is restarted, the incomplete transactions are identified and the updates relating to these transactions are “backed-out” or some extra procedures or tools may be required. Application Consistency There are ways of ensuring that if a copy is taken, or if a system is shut down, all necessary transactions within a database are complete and caches are flushed inorder to maintain consistency. Scripts can be written, following best practice for each application to ensure processes take place in a certain order, or there applications which can automate these procedures for each application. Some technologies use agents which are application specific. The choice is again down to importance of data, RPOs, RTO’s and the available budgets within the organisation. © Copyright 2013 EMC Corporation. All rights reserved. 38
