“SMS Site Backup failed while creating the snapshot using the VSS services. Aborting the backup operation.”

“SMS Site Backup failed while creating the snapshot using the VSS services. Aborting the backup operation.”

I have ConfigMgr installed with the Site Server and Site Database Server running on different servers.

I’m seeing a Status Message ID 5047 for the SMS_SITE_BACKUP Component stating:

SMS Site Backup failed while creating the snapshot using the VSS services. Aborting the backup operation.

If I look in the smsbkup.log I see:
