Free CompTIA A+ 220-1102 Practice Question

A differential backup includes data that has changed since the last full backup. This requires more space and time than an incremental backup, which only captures data changed since the last incremental backup, but less than a full backup, which copies all data. In a recovery scenario, a differential backup would be restored after a full backup, and only the latest differential backup is needed, in contrast to an incremental backup, where all increments since the last full backup would be necessary.
