You take a full backup every Sunday and a daily differential backup each morning. Assuming you don't have software that would simplify the process, how many backups would you have to restore following a disaster on Friday?

With differential backups, you only need to restore the last full backup and the last differential backup. If you were using incremental backups, then you'd need to restore the last full and all intervening incremental backups for full recovery.
