You should use an Incremental backup scheme to perform multiple backups of only those files that are modified since the last normal backup.
Key Takeaway: An incremental backup will back up only those files that have been changed since the last backup of any type. This provides the quickest means of backup, since it makes copies only of files that have not yet been backed up. The disadvantage with this backup scheme is that in order to perform a full restore, you need to restore the last full backup first, followed by each of the subsequent incremental backups to the present day in the correct order.
