Note:The system tests the configuration on one of the selected VMs. After you save the

configuration, the system will then test the configuration on all selected VMs and notify you of any

errors.

9. After receiving confirmation that the VSS configuration is compatible with one VM, click Save to enable

quiesce for the VMs and save changes.

Using Log Truncation for VSS Backups

To avoid overfilling a Windows system disk or partition with log files, which can lead to application downtime,

it is important to truncate transaction logs after a VSS backup completes.

Enable log truncation on the ConfigureVSSLogin dialog box (see Preparing a Windows System for VSS

Backups). After log truncation is enabled, SmartMotion™ automatically truncates logs after a backup has

completed successfully.

If you are not using SmartMotion, you need to manually initiate log truncation after a backup completes. Use

the vmPRO appliance's GUI (see below) or the vmPRO appliance's VMware Console (see vmPRO

Console Commands – vss) to manually initiate log truncation.

Manually initiate log truncation from the vmPRO appliance's GUI

1. On the vmPRO appliance GUI, click the VMs button to display the VMsConsole.

2. Click the VirtualMachines tab to display the Virtual Machines tab view, as needed.

3. Click CompleteBackup(VSS) to truncate the transaction logs.

Note:The CompleteBackup(VSS) button displays only after backups are run for VMs that have

log truncation enabled. It can take up to an hour after the backup starts before the button displays.

Uninstalling the VSS Writer

If you need to uninstall the Quantum VSS Writer, use Add/RemovePrograms on the Windows Control

Panel. If you encounter an error uninstalling the VSS Writer, update the Uninstall key in the Registry Editor.

Update the Uninstall key

1. From the VM's Windows Start menu, select Run to open the Run dialog box.

2. In the Open field, enter regedit and click OK to display the RegistryEditor.

3. Navigate to the following key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\

{13C110B5-F313-4bc5-B700-D7B4B6A70A49}
