Which statement best describes a full backup?

• A. It copies all data.
• B. It copies only new or changed data since the last backup.
• C. It copies data only from a specific folder.
• D. It copies system settings only.

Answer: (A)

A full backup copies every file and folder that you’ve chosen to back up, creating a complete snapshot of all data at that moment. Because it includes all data, you can restore everything from that single backup without needing any previous backups, which makes the restoration straightforward and independent of other backups. This is why it’s described as copying all data. It does require more storage space and longer time to complete than other backup methods, since you’re duplicating everything each time. Other backup types, like those that copy only new or changed data since the last backup or that focus on a specific folder or only system settings, are faster and save space but don’t capture the entire dataset in one backup.
