PostgreSQL Recovery

PostgreSQL software provides several methods and procedures for database recovery. The choice of recovery method should adhere to the RPO (Recovery Point Objective) and RTO (Recovery Time Objective) of the organization. When planning for recovery, it's important to consider the potential impact on downtime for critical business applications. Some recovery methods, such as point-in-time recovery, can restore the database to the state of the last committed transaction up to a required time or to a specified System Change Number (SCN). It is necessary to review the recovery policies regularly and implement Disaster Recovery (DR) drills periodically to validate the backup media's validity for recovery. Furthermore, a DBA’s core competency is judged by their ability to recover databases based on business Service Level Agreements (SLAs).
