Which of the following is NOT a valid model category in ServiceNow?

In ServiceNow, model categories are used to classify different types of assets managed within the Hardware Asset Management module. The valid model categories include Hardware, Consumable, and License, each representing different asset types and their specific management processes.

The Hardware category represents physical devices that an organization uses, like servers or desktops. Consumable refers to items that are used and depleted in the course of operations, such as supplies and parts. The License category deals with software licenses that are essential for monitoring and managing software asset compliance and usage.

The category labeled as Backup, however, does not exist as a recognized standard model category within ServiceNow's framework. While backups might be an important consideration in IT asset management, they do not fit into the defined categories used for classifying assets in the Hardware Asset Management module. This distinction is key to understanding asset management practices and their implementation within ServiceNow.
