I found this tools from the Internet which provide some impress features to allow the users to manage the backup and VM explorer as an alternative from the only tools we have on the VM infrastructure today. Trilead is able to work as explorer for you to  manage, review, monitor and task execution on your VM infrastructure farm.  It able to provide the inventory listing in details for us to manage the VM infrastructure as an alternative. Screenshots is attached for reference purposes.

The biggest benefits I see from this is really about the VM images backup. As many of us are trying to build the expensive solution on VCB, this may be an alternative solution to achieve the similar solution with less budget available. It allow the backup to be done with no down time and you can store the images and folder to any storage you need, include backup tape, dedupe devices or SATA storage for recovery purpose. I will expect to see more improvement to be come in the next version as it will be a good idea to look into this products for alternative solution to manage the VM infrastructure today.
