I'd like to remind you about my solution for the Spectrum Protect management tool, TSMExplorer.

Especially in terms of integration with VMware. The program connects via the VCenter API, retrieves virtual machine data, compares it with current virtual machine backups, and provides you with an expanded view both in the user interface and in reports.
And if you have more privileges, you can set tags directly from the program.
