Which describes incremental backups?

Explanation:
Incremental backups focus on efficiency by saving only what has changed since the previous backup. After an initial full backup, each incremental run captures just the data that was modified since the last backup event, whether that was another incremental or the original full backup. This keeps each backup small and quick, reducing storage and transfer time. That’s why the statement describing copying only changes since the last backup is the best fit. A backup that copies everything every time would be a full backup, which isn’t incremental. Copying data randomly isn’t how backups operate, and copying changes since the last full backup describes a differential backup, not incremental.
