Differential backups save all changes made since your last full backup. Where incremental backups only store changes since the last backup of any kind, differential backups track all changes since your last complete backup. For example, if you make a full backup on Monday and changes on Tuesday and Wednesday, a differential backup on Wednesday saves both days’ changes. This makes restoring your site simpler.
