Which type of backup restores the entire data set to its last full form?

• A. Incremental backup
• B. Differential backup
• C. Full backup
• D. Snapshot backup

Answer: (C)

The type of backup that restores the entire data set to its last full form is a full backup. This process involves creating a complete copy of all data files, configurations, and system information at a specific point in time. When a full backup is executed, it ensures that every aspect of the data is captured and can be restored in its entirety, without the need to reference any other backup sets. In contrast, an incremental backup captures only the data that has changed since the last backup (whether that last backup was a full backup or another incremental one) and requires previous backups to restore the entire dataset. A differential backup, while also focusing on changes, accumulates the changes since the last full backup, meaning it can grow larger over time and also requires the last full backup in the restoration process. A snapshot backup, on the other hand, takes a snapshot of the data at a specific moment but may not provide a complete backup suitable for full restoration depending on the system it supports. Ultimately, to restore an entire data set to its last full state seamlessly, a full backup is the appropriate choice.
