Which of the following BEST describes the difference between differential and incremental backups?

An incremental backup typically requires more tapes or files for restoration because you need the full backup plus every subsequent incremental backup.

A differential backup generally takes more time to complete than an incremental backup because it backs up all changes since the last full backup, which accumulates over time.

To restore a full system with a differential backup strategy, you need the last full backup and only the *latest* differential backup, as it contains all changes since the last full backup. In contrast, an incremental backup requires the last full backup *and all subsequent incremental backups* in sequential order to fully restore, meaning differential typically requires fewer tapes for a complete restoration.

The cost of an individual backup tape is not a technical distinguishing factor between differential and incremental backup types.
