From the navigation pane, go to Protect > Dynamics 365.
The Dynamics 365 apps page appears.
In the Name column, click the app that contains the table or the environment that you want to exclude.
The app page appears.

To exclude a table, on the Tables tab, in the row for the table, click the action button , and then click Manage > Exclude from backup.
To exclude an environment, on the Content tab, in the row for the environment, click the action button , and then click Manage > Exclude from backup.
