automatic wordpress backup not working for

Configured the auto-backups last week. First backup should have happened last Friday night. There is still no backup and, when I login to the WordPress admin for the site and go to the Snapshot Managed Backups tab, there is a message saying the backup is running. I have successfully set this up for other sites but can't figure out what is wrong with this one. That said, I will point out that content on two subdomains for this site (info. and blog.) are actually hosted and managed via HubSpot. The sub-domains are backed up there. What I intended with the Snapshot set up was backups for the main domain.

This also applies to the site
