Is it possible to copy a vdisk that is not fully allocated, without it fully allocating to the copy?

Essentially I have a 60GB vdisk with only 15GB in use. If I attempt to copy it in any way it copies 60GB fully, not 15GB. 

# qemu-img info vdisk1.img

disk size: 14.9 GiB

    You can achieve this using rsync to do the copy with the --sparse parameter.   I think the cp command  has an equivalent option.

    cp --sparse=always /path/to/source /path/to/dest
