Oracle Database Administration from Zero to Hero - Introducing Backup and Recovery

This lecture covers recovery in Oracle databases, focusing on data failure categories, backup and recovery planning, and Oracle's recovery solutions. It explains the importance of understanding different types of failures, such as media, user, network, and disasters, and how to develop a recovery plan with RTO and RPO objectives. The lecture also compares Oracle technologies like RMAN, Data Guard, and RAC, emphasizing the need for a tailored recovery strategy based on system value and budget. The course will focus on using RMAN for implementing backup and recovery policies.
