Backs up only those files created or changed since the last normal or
incremental backup (Those files with the archive bit on). This method is
also used in combination with a periodic full backup. For example, a
Normal/Full backup on Mondays and a differential backup on the
remaining days of the week. Backs up more data per day but
restoration time is quicker. In case of a restore, you will only need to
restore the last normal backup and the last differential backup

normal/full backup on Mondays and an incremental backup on the
remaining days of the week. Backs up less data per day so backup
times are quicker. However, restoration times are generally longer
because you will need to restore the last normal/full backup as well as
all incremental backups since the last normal backup
