An Incremental backup will back up any files that have changed since the last backup taken (regardless of whether this previous backup is full or incremental)
A differential backup will back up ALL files changed since the last full backup.
So, if you need to restore a file using an incremental backup routine, you potential require all tapes since your last full backup.
If you use a differential backup routine, you will only require the full backup tape plus the last differantil backup tape.
