Thank you for asking this question on the **Microsoft Q&A Platform. **
Is the information in the Backup Jobs report helpful?
But, if you require a more detailed report, the best option is configure a Log Analytics workspace in your Recovery Services vault and through the log console, you can generate the report with the specific information that you require.
The downside of this option is that you cannot generate reports of the data before the configuration of the log analytics.
Hope this helps!
