AWS Technical Essentials Practice

AWS supports disaster recovery primarily through automated backups and data replication. This approach allows organizations to safeguard their data and applications by creating copies of critical data in different geographical locations.

Automated backups ensure that data is regularly and systematically backed up without manual intervention, minimizing the risk of data loss. These backups can be scheduled at specific intervals and are stored in durable AWS storage solutions like Amazon S3 or Amazon RDS snapshots.

Data replication further enhances disaster recovery by continuously copying data from one location to another, often in real-time, ensuring that there is an up-to-date copy available in case of a failure. This is particularly useful for mission-critical applications that require high availability.

Together, these features enable organizations to recover data quickly and efficiently, thereby maintaining business continuity in the face of disasters. AWS offers various options for disaster recovery architectures, including pilot light, warm standby, and multi-site solutions, allowing businesses to choose the level of recovery strategy that best meets their needs based on factors such as recovery time objective (RTO) and recovery point objective (RPO).
