For everyone who uses Veeam to backup Nutanix, now in version 12.2 it is possible to have the "Dynamic backup job scope"
It leverage Prism Central VM categories (a.k.a., “tags”) to facilitate automatic VM inclusion into backup jobs based on Prism Central VM category affiliation.
Definition of category from Prism Central Infrastructore Guide: https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2024_2:ssp-ssp-categories-manage-pc-c.html
A category is a grouping of entities into a key-value pair. Typically, new entities are assigned to a category based on some criteria. Policies can then be tied to those entities that are assigned (grouped by) a specific category value.
For example, you might have a Department category that includes values such as engineering, finance, and HR. In this case, you could create one backup policy that applies to engineering and HR and a separate (more stringent) backup policy that applies to just finance. Categories allow you to implement a variety of policies across entity groups, and Prism Central allows you to view any established relationships quickly.
The following hypothetical example illustrates the relationship of four policies (Backupbasic, Engenvironment, Hourly alerts, and Daily backup) tied to three departments (Eng, Fin, and HR) that apply to 30+ VMs in each department.
