I'm attempting to enable the SharePoint and SQL granular functionality within our VMware backups, so on one system that was otherwise working as expected with NetBackup under the default VMTools configuration, I installed the Symantec VSS provider. As expected, the installation process uninstalled the VMware Snapshot Provider (and I have verified that it is no longer installed within \Program Files\VMware\VMware Tools\Drivers, and its Windows registry entry is gone), and following a reboot of the VM, the Symantec VSS was reportedly successfully installed. However, backup attempts are now failing to quiesce, which was functional before I underwent this process.
