Which statement best describes a full backup?

• A. Only copies modified files since the last backup
• B. Compresses all files to save space
• C. Making a copy of every file on the computer or network
• D. Stores data in a different format

Answer: (C)

A full backup copies every file in the chosen data set, creating a complete snapshot in one backup. This means you have all data in one place, making restoration straightforward—no need to rely on previous backups. However, it requires more storage and takes longer because every file is copied, even if nothing changed since the last backup. The other ideas describe different concepts: copying only files that have changed since the last backup is an incremental approach; compressing files saves space but doesn’t change which files are included; storing data in a different format is unrelated to the scope of the backup.
