You can back up Salesforce metadata. By default, the Metallic software does not include the Salesforce metadata in backups.
Note: You cannot backup metadata from a managed package. Metadata from a managed package, such as Apex classes, triggers, and Lightning Web Components, are only accessible to the provider of the managed package.
From the navigation pane, go to Protect > Salesforce.
The Salesforce page appears.
In the Name column, click the app.
The app details page appears.
On the Overview tab, in the Content section, click Manage.
The Content dialog box appears.
Select the Metadata check box.
