Page 3 Why Protect Your Data? Protect against accidental corruption or loss of data  Human or program errors  System failures (hardware, software, network) Protect against malicious corruption or loss of data  Viruses, Sabotage Protect against local and wide area disasters  Disaster Recovery/Business Continuance Because you have to!  HIPAA, Sarbanes-Oxley, SEC 17 A, EU DPA, etc. No longer an option!

Page 4 Interesting Points to Consider On average, companies value 100 megabytes of data at more than $1 million (Source: Ontrack Data International) Estimates show that 1 out of 500 data centers will have a severe disaster each year 93% of companies that lost their data center for 10 days or more due to a disaster filed for bankruptcy within one year of the disaster. 50% of businesses that found themselves without data management for this same time period filed for bankruptcy immediately. (Source: National Archives & Records Administration in Washington.) The value and vulnerability of data, and the cost of not protecting

Page 9 Key Considerations Recovery Point Objective (RPO)  How much data can you afford to lose? Recovery Time Objective (RTO)  How long can you afford to be without your data?  What are downtime costs?  What are downtime implications? Data Classification  How critical is your data to the operational and financial viability of the company?  All data is not created equal Budget  How much money can you afford to spend? Source: Enterprise Storage Group “The Evolution of Data Protection” RTO vs. RPO vs. Budget $ trade-offs as one size does not fit all…
