Absolutely, you can use the “Protected VMs” report in Veeam ONE. The report helps you identify which VMs in your environment function without proper protection and make sure the existing backups and replicas meet established RPO requirements:

Please check out the documentation here: https://helpcenter.veeam.com/docs/one/reporter/protected_vms.html?ver=110

That is correct. Are you looking to monitor the RPO of a backup job or a backup copy job?

How many instances/virtual machines are you looking to monitor?

Then the community edition is not enough. This edition is for up to 10 instances.

I just would also like to add. A bit more information on the scenario could help here.

Some clients are happy to just have an email of every successful backup to gauge their RPO as an estimate. This could be done via the email notifications of a job.

Depending on the resources available someone achieved something similar with PowerShell here.

I mentioned above about Veeam One being bundled in Veeam Backup Essentials in case your client is licensed that way. Veeam One is a great solution with many more features than just that single report but hopefully one of these solutions will help or otherwise more context would help us steer you.
