Good day Robert,

Thanks for being a part our Metallic Community! Based on what I can see along with what I’ve researched, this is what is being received back from the Salesforce API during the batch request. Typically Salesforce requests the user to contact their Support team to review further. However, I see you have a Metallic case open with our Support team, we’ll review this further as you mention you don’t want to exclude and reach out to you first thing Monday morning. 
 

Hope that helps! Have a great day. 
Mike

Adding case solution:

Explained that the object can be excluded from backup or it can be ignored since it is an ignorable error.
