Which backup type copies all files and is commonly scheduled to run regularly?

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

Answer: (D)

Copying every file in the selected data set into one backup is what a full backup does. This creates a complete restore point, so you can recover everything without needing previous backups. Because it captures everything in one pass, it’s common to schedule full backups regularly to maintain a solid baseline—think weekly or at regular intervals—even though the process uses more time and storage. Other backup types save only changed data since the last backup (incremental) or since the last full backup (differential), which changes how restores are performed and how much space they require. A mirror backup aims for an exact duplicate at the time of the backup, differing in purpose and implementation from a traditional full backup. The key is that a full backup provides a single, complete copy of all data for straightforward restoration.
