Challenge

A job backing up/replicating both Linux and Windows VMs needs to be configured.

Solution

Enable both the ‘Enable VMware tools quiescence’ option when specifying advanced settings at the ‘Backup Destination’ step of the wizard and the ‘Enable application aware processing’ option at the ‘Guest Processing’ step.

In the Guest OS credentials section, specify guest operating system credentials for target VMs that are required to deploy the agent. Please note that the user name must be supplied in the DOMAIN\USERNAME format.

Click Advanced… to specify advanced options for Veeam VSS. The Advanced Options window contains a list of VMs that will be processed with Veeam VSS and indexing tools. You can exclude specific VMs from processing or add them:

  • To add a VM, click Add VM… and select a VM you want to process. The Add objects list contains only those VMs that you added to the backup job. To display all VMs in the virtual infrastructure hierarchy, select the Show full hierarchy check box.
 
  • To exclude a VM, select it in the list and click Remove.

To provide granular quiesencing option for a VM, select it in the list and click Edit. In the Applications section on the Applications tab select the ‘Disable Application processing’ or ‘Ignore application processing failure’ option for all Linux machines.

More Information

When you select both the ‘Enable VMware tools quiescence’ option and the ‘Enable application aware processing’ option for a job at the same time, the VSS module will  be used for processing backed up and replicated VMs at first. In case VSS fails or is disabled for a specific machine (e.g. Linux VM), this machine will be processed with the VMware tools quiescence option instead.
