Commvault Virtual iDA - Change proxy mount path used for vdisk backups

So I needed to backup an old ESXi server that was incompatible with VADP.  VCB fallback had to be used on this proxy machine in order to get full disk level backups.

Prerequisites

• Install VCB on proxy
• Install VMware Converter on proxy
• Proxy must have ample disk space to accommodate vmdk's

My problem was that I did not have ample disk space in the default location where the proxy copies these vmdk's.  The default path is "C:\Program Files\CommVault\Simpana\iDataAgent\JobResults"

Location
Windows	HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\<Instance>\
Unix	Not Applicable
NetWare	Not Applicable
Key	VirtualServer (standard)
Value	dVMSnapMountPath (optional)
Value Type (Windows only)	STRING
Valid Range	<full_mount_path>
Default Value	<job_results_folder>
Created in	Proxy Computer
Description	This registry key allows you to change the mount path used for backups to a location other than the original proxy computer.
Applies To	Virtual Server iDataAgent
