This document discusses disaster recovery concepts including business continuity, disaster recovery, and high availability. It defines these terms and explains that disaster recovery is a subset of business continuity focused on recovering computing environments after failures or disasters. The document also discusses the importance of data protection and outlines different disaster recovery strategies and technologies like backup, replication, clustering, and snapshots that can help minimize data loss and downtime in the event of an outage or disaster.

1. What is Disaster Recovery and what can you do about it?

2. Business Continuity Business Continuity Management is a holistic management process that identifies potential impacts that threaten an organisation and provides a framework for building resilience and the capability for an effective response which safeguards the interests of its key stakeholders, reputation, brand and value creating activities. ( Source: British Standards Institute PAS56) Disaster Recovery Total loss of a computing environment from supporting the business. Recovery of the computing environment from an error or major site failure. Subset of Business Continuity . High Availability A rapid process to move a business transaction from a failed component to a functioning component with minimal impact to the organisation and environment. Subset of Disaster Recovery .

3. What is most important to any organisation? People Data and systems Protecting data and systems is difficult Data is growing 50-80% per year (source: Gartner) IT infrastructure is complex Server Application Database Web Server Windows Environment Storage

4. Software bug Virus Data corruption Accidental delete Dropped table D.o.S. Attack CPU fault Disk failure Array failure Host Bus Adapter Network Card Software Fire Power Outage Terrorism/War Flooding Storms Hurricane Logical Outages Component Outages Site Outages

5. Have you ever lost data? Gartner estimates that 40% of businesses that lose ALL their data go out of business within 5 years.** How much would 1 hour of downtime cost you? Only 26% of all organisations have calculated the cost of downtime.* Do you test your disaster recovery plan yearly? New studies say that up to 66% don’t.* * Source: VERITAS Disaster Recovery Research. ** Source: Gartner.

6. An explanation of core disaster recovery concepts and technologies.

7. Amount of data loss acceptable The point to which data must be restored RECOVERY POINT OBJECTIVE (RPO) Amount of time it takes to come back online The time by which data must be restored RECOVERY TIME OBJECTIVE (RTO) Days Mins Hrs Wks Secs Recovery Point Mins Days Hrs Secs Wks Recovery Time

9. How often do you backup your data? Backup is the foundation of any good DR strategy as it is a point-in-time snapshot of data. The more often you backup the safer you are. How much data loss can you afford? (RPO) Data is the lifeblood of most organisations and must be protected at all costs. New laws and regulations also dictate requirements for acceptable data loss. Not all data is created equal, and because there’s a high cost associated with safeguarding data, pick and choose what to protect. How much downtime can you afford? (RTO) Clustering (fastest) and Bare Metal Restore (fast) simply automate the tasks of getting back to business faster. The more critical the system the higher the need for automation. Only 5% of organisations use clustering to minimise downtime Source: VERITAS Disaster Recovery Research, Sept. 2004

10. Backup and Disaster Recovery Strategy

11. Only backup provides: Cost-effective portability of data Protection against complete data loss Protection against viruses and data corruption Managed multiple point-in-time copies of data Integrated archival management Integrated desktop/laptop protection Backup does not provide Instant access to data (short RTO) Minimum data loss (short RPO)

12. Network share is the most popular and least effective. WHERE DO YOU FALL? Network Share 55% Users Copy Locally 7% PC Backup Software 7% Synch Products 4% Software Solution 6% Server Backup 6% No Solution 15%

13. Backup is the cornerstone of any disaster recovery plan Last line of defense For disaster recovery planning, the backup solution must provide: Technologies that enable faster recovery and reduce costs System level protection, not just data Automation that works when disaster strikes Protection for servers and laptops/desktops
