You can transfer the volume over the network and end up with another
volume if you create one on $remotehost beforehand of the same size.
Then have netcat listen on some port, say 9000, and pipe it to that new

$ nc -l 9000 | sudo dd of=/dev/vg/backup

Then on the source:

$ sudo dd if=/dev/mapper/myvolume | nc $remotehost 9000
