Article Applicability

This article is only relevant to environments still using a Windows-based vCenter (vSphere 6.7 and older) with the vCenter database hosted on a Microsoft SQL Instance.

Per VMware's Blog: Reminder: vSphere 6.5/6.7 End of General Support

  • The End of General Support for vSphere 6.5 and vSphere 6.7 is October 15, 2022. 
  • The End of General Support for vSphere 6.5 and vSphere 6.7 also means the End of General Support for Windows based vCenter Server instances
Protecting VCSA in vSphere 7.0 and newer
Starting with vSphere 6.7, the vCenter Server Appliance (VCSA) has a built-in file-based configuration backup option, which VMware recommends for protecting the VCSA. The built-in backup method creates a seamless native method of both protecting and restoring the VCSA.

Challenge

When operating a Windows-based vCenter, if the VM running Microsoft SQL that is hosting that vCenter's database (VCDB) is processed by a backup job with Application-Aware Processing enabled, the VSS freeze operation that occurs during Application-Aware Processing will freeze the vCenter database. This database freeze will cause Application-Aware Processing to fail as the vCenter's frozen database cannot process the ESXi host's snapshot creation response.

Solution

By default, Veeam Backup & Replication will attempt to identify and automatically exclude the VCDB (default name of the vCenter Database) from the VSS freeze operation, however, the database detection automatic exclusion may not work correctly when the VCDB is hosted on a separate machine from the Windows-based vCenter VM.

To resolve this, enable the Database Exclusion menu option and configure a database exclusion.
