Cloning beaglebone black image

Hello,

I’m trying to make image of my beaglebone using : sudo dd if=/dev/mmcblk0 bs=1M | ssh machinekit@192.168.7.2 ‘dd of=/home/rimvis/Desktop/bbb.img bs=1M’,
but everytime i get error : dd: opening `/home/rimvis/Desktop/bbb.img’: No such file or directory. Obviously that directory exists. Any ideas how to fix it?
