Hello A-A,

       Please refer below article an follow all points, especially point 6 for SharePoint (SP) Backup policy configuration. 

https://www.veritas.com/support/en_US/article.HOWTO73100

   Make sure you us have NBU Clients Installed on all servers in the SP farm. 

   Check the configuration in above article if its SP 2016, as service account configuration is different.

Hope this helps. Please Mark solution if issue is resolved.
