技術者は、迅速に復元する必要があるバックアップおよびリカバリ ソリューションを設定しています。ストレージ スペースは考慮されません。技術者は次のどのバックアップ方法を実施する必要がありますか。
正解:C
The correct answer is C. Full Backup.
* A Full Backup creates a complete copy of all selected data every time it runs. This method ensures the fastest possible recovery time because all the necessary data is contained in a single backup file.
* Since storage space is not a concern, full backups are ideal because they avoid the need to restore multiple incremental or differential backups.
* Recovery Time Objective (RTO) is minimized, making full backups the best choice for quick restoration.
Why Other Options Are Incorrect:
* A. Differential Backup - Backs up only the data that has changed since the last full backup. While faster to restore than an incremental backup, it still requires both the last full backup and the most recent differential backup for restoration.
* B. Synthetic Backup - A synthetic full backup is created by combining previous full and incremental backups without needing to back up data again from the source. While efficient in terms of backup creation, restoration can be slower compared to a traditional full backup.
* D. Incremental Backup - Backs up only data that has changed since the last backup (whether full or incremental). While efficient in storage, restoring from incremental backups can be slow because multiple backups must be restored in sequence.
