What are two options available to restore an Autonomous Data Warehouse?

Restoring an Autonomous Data Warehouse can be effectively achieved by selecting the backup from which the restoration needs to occur. This option allows the database administrator to specify the exact state of the database they wish to restore from, leveraging the backups that have been created at various points in time. The ability to choose a specific backup is essential for scenarios where recent changes need to be discarded, or where an earlier configuration of the database is desired.

When considering the context of database backup and recovery, selecting a backup is a fundamental approach, as it directly utilizes the stored data sets that represent the database's state at the time the backups were created. This method ensures that data integrity is maintained while facilitating a smooth recovery process.

While specifying a point in time or selecting snapshots may also appear feasible, they focus on distinct aspects of the recovery process. Snapshots are typically more limited in frequency and may not provide as much granularity as desired. Point-in-time recovery techniques often involve additional complexities, such as the need for archival logs, which are not part of the traditional backup selection process.

In conclusion, choosing a specific backup for restoration is a straightforward and reliable approach that aligns with standard database recovery methodologies, making it the most appropriate selection in this context.
