[Users] export VM

Hi all, I see that exporting a VM with ThinProvisioning will make an image with the full disk size, instead of the currently used size: - VM has a 20GB disk - installed OS is taking 1.3GB - exported disk is taking 20GB Is this mandatory? Couldn't the export make a file with the same size, also sparse? It seems it only does a copy of the folder and the normal linux cp can make a sparse copy. thank you, Cristian Falcas
