The Cisco ISE must conduct configuration and operational backups when changes are made or must schedule backups weekly, at a minimum.

If this information is not backed up and a system failure was to occur, the security settings would be difficult to reconfigure quickly and accurately, thus increasing adverse impact of the outage. There are two types of ISE backups: Configuration backup and operational backup. This requirement pertains to the configuration. Since the administrator may forget to immediately backup each time changes are made, a scheduled weekly backup is a best practice and preferred. However, there may be operational impacts for the scheduling option that necessitate immediate backup after configuration changes method be used.
