What is a significant advantage of using incremental backups in Oracle Autonomous Database?

Using incremental backups in Oracle Autonomous Database offers a significant advantage because they focus on backing up only the changed data since the last backup was taken. This targeted approach minimizes the amount of data that needs to be processed compared to full backups, which can significantly reduce the workload on the system during backup processes.

By not needing to back up the entire database each time, incremental backups lighten the strain on resources such as CPU, memory, and storage, enabling other operations to continue with minimal impact. This results in a more efficient backup operation, as it allows for quicker completion times and less interference with ongoing database activities.

In this context, while options discussing real-time backup performance without downtime, no storage requirements, or unlimited database size may seem beneficial, they do not accurately capture the critical efficiency and resource management gains that incremental backups provide.
