Hello dear fellows,

I've been using Proxmox since few months.
And I'd like to take this opportunity to thank the amazing folks who created this Amazing, and handy system.

Recently, for some reason (not worth mentioning) my Proxmox Host failed to boot and I had to move all the VMs to a physically new box.

My question is.. what's the best way (ie. fastest) to move the qcow2 images very quickly from one node to another?
Moving the image directly using tools like rsync or scp take decades to complete since it's moving the whole size of the image. For example.. if the image was sized 500Gb and only consumed space is 10Gb, it moves 500Gb which takes horrible long time to complete..

I need help, I assume there must be a way to move only consumed data.
I Googled for hours, didn't get the right answer.

mount the disk directly (USB, SATA ...) copy it with "cp -a"
