A full backup captures all data, regardless of whether it has changed since the last backup. This ensures that a complete copy of the data is made every time. * Full (Answer E): A full backup includes every file in the system, regardless of changes. * Incremental (Option A): Backs up only files that have changed since the last backup (full or incremental). * Differential (Option B): Backs up all files changed since the last full backup. * Archive (Option C): Typically refers to long-term storage of data, not a type of backup process. * Snapshot (Option D): Captures the system's state at a given point in time, often used in virtual environments.
