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

  • 9. <ul><li>How often do you backup your data? </li></ul><ul><ul><li>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. </li></ul></ul><ul><li>How much data loss can you afford? (RPO) </li></ul><ul><ul><li>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. </li></ul></ul><ul><ul><li>Not all data is created equal, and because there’s a high cost associated with safeguarding data, pick and choose what to protect. </li></ul></ul><ul><li>How much downtime can you afford? (RTO) </li></ul><ul><ul><li>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. </li></ul></ul><ul><ul><ul><li>Only 5% of organisations use clustering to minimise downtime </li></ul></ul></ul>Source: VERITAS Disaster Recovery Research, Sept. 2004

  • 12. <ul><li>Network share is the most popular and least effective. </li></ul><ul><li>WHERE DO YOU FALL? </li></ul>Network Share 55% Users Copy Locally 7% PC Backup Software 7% Synch Products 4% Software Solution 6% Server Backup 6% No Solution 15%
  • 13. <ul><li>Backup is the cornerstone of any disaster recovery plan </li></ul><ul><ul><li>Last line of defense </li></ul></ul><ul><li>For disaster recovery planning, the backup solution must provide: </li></ul><ul><ul><li>Technologies that enable faster recovery and reduce costs </li></ul></ul><ul><ul><li>System level protection, not just data </li></ul></ul><ul><ul><li>Automation that works when disaster strikes </li></ul></ul><ul><ul><li>Protection for servers and laptops/desktops </li></ul></ul>
