The Symantec VSS Provider helps Backup Exec protect VSS-aware applications, such as Microsoft Exchange, SQL, and Active Directory. The Symantec VSS Provider provides an automatic snapshot of the Windows applications and databases for each backup job.
Some of your Guest virtual machines may already have the VMware VSS Provider. However, only one VSS Provider can be used on a Guest virtual machine. Therefore, you must uninstall the VMware VSS Provider.
When you install the Remote Agent for Windows Systems on a Guest virtual machine, the Symantec VSS Provider is installed automatically. You can also install it manually from the Backup Exec installation media.
