I'm having some trouble getting this working. I originally installed PowerCLI 6.5, and it worked far enough to create the backup VM, but then I got errors when trying to select it. Got something like "object is not an instance of object" errors and could not continue. I realized later that PowerCLI 6.5 is not compatible with our 6.7 vCenter Server. I removed PowerCLI 6.5 and installed 11.5, and now this fling will not even start because it doesn't see PowerCLI at all. Likely due to it not being "installed" any more, and rather being installed through Powershell now. Has anyone got around this restriction? Maybe this fling is not used anymore as there are very few comments recently. If this is true, how are you backing up writables and app volumes?
