The preserve identities feature is not included in the logical configuration backup operation type. This type of backup includes the configuration settings that are logically grouped, such as service profiles, policies, and pools, but does not include the unique identifiers or configurations that are specific to a particular system or setup, which are preserved in a full state or system configuration backup.
References := For detailed information on the different backup operation types and their characteristics, please refer to the official Cisco documentation on Implementing and Operating Cisco Data Center Core Technologies (DCCOR), specifically the sections related to backup and restore operations within the Cisco Unified Computing System (UCS) Manager1.
