You can use the Commvault Plug-In for VMware vCloud Director (vCD) to back up virtual machines.
Note: To back up an unprotected virtual machine, you must verify that the virtual machine has an associated server backup plan. If it does not, you must associate a plan to the VM. For more information, see Modifying Server Backup Plan Using the Plug-In for VMware vCloud Director.
In vCloud Director, click the More menu icon, and then select the plug-in option, Commvault Data Protection.
If you are using an older version of vCloud Director (versions 9.5 - 10.0), click the Cloud Resources menu icon, and then select the plug-in option, Commvault Data Protection.
The Virtual Machines tab appears.
On the VM Protection tab, select the virtual machine to back up, and then click Back Up Now.
A Backup confirmation window appears.
Click Back Up.
