Quizplus · Accepted Answer

While all of the datafiles, archive logs, and redo logs can technically be recovered from a backup, it is not preferable or necessary to recover all of them in every situation. For example, if only one datafile or one redo log is corrupted, it may be sufficient to recover only that specific file rather than the entire set. Additionally, restoring and recovering large volumes of data can be time-consuming and resource-intensive, so it may be more practical to prioritize critical files or logs for recovery.
