Hello @Sivakumar Shankar ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
There isn't a direct way to review the list of VMs that are being backed up in a subscription along with the backup status. However, you could use azure backup center to view list of all VMs that are configured for backups across all the resources groups under all or specific subscriptions along with the latest recovery point timestamp and protection status like highlighted in the below screenshot
Portal.azure.com->Search for Backup Center and under left pane select Backup Instances
Note: The above highlighted blade doesn't have an export option, hence you can click on the "Open query" button on the top which redirects you to use "Azure Resource Graph explorer with the query that can fetch you the desired output which you can download in a CSV format for your use.
