Mount a remote filesystem locally with fuse-sshfs:

> sshfs ghost@192.168.0.10:/home/ghost /tmp/mnt

Unmount with:

> fusermount -u /tmp/mnt

Set it up on /etc/fstab with:

> sshfs#bkp@bkp.a-server.ninja:/media/store1/bkp /backup fuse defaults,allow_other,reconnect,delay_connect 0 0

Make image backup of sda1 and sda2 from one machine and pass it through ssh to another.
