The required backup in most production systems is the backup where you do not need to shut down your database. It is called an inconsistent, open or online backup. When taking an inconsistent backup, although you may face performance degradation, users are able to make changes to the database. It is recommended that an inconsistent backup should be done during the off-peak hours.
