The document discusses strategies for protecting data, including: 1. Implementing a well-defined data protection architecture using Oracle Database security controls and services like Data Safe to assess risks, discover sensitive data, and audit activities. 2. Using high availability technologies like Oracle Real Application Clusters and disaster recovery options like Data Guard and GoldenGate to ensure redundancy and meet recovery objectives. 3. Addressing challenges with traditional backup and restore approaches and the need for a new solution given critical failures and costs of $2.5M per year to correct.
