So, just realised the pinned link at the start of this thread is 3 years old as is Spaceinvaders video!
Never the less this is all still good stuff.
I am however having issues getting it to back up a Linux vm.
Its loading its image from a converted image for my HassIO server.
The log output is -
2019-03-12 12:22 information: started attempt to backup
2019-03-12 12:22 warning: HassIO can not be found on the system. skipping vm.
2019-03-12 12:22 information: finished attempt to backup
This is what the config looks like... any ideas why it cant find the VM?
