Not sure exactly what you mean with the space issue, but in any case:

On the machine receiving the dump:

ssh <machine_being_backed_up> dump -0af - <what_to_dump> > backup.dmp

Of course that the user that you login as, needs to have read
permissions for the files/devices being read. To avoid allowing ssh
logins as root, you might want to add a user to the 'operator' group and
then ssh as that user.

If you are doing this over the network, you might want to create a
script on the server side, to pipe the dump through gzip, to save some
bandwidth. Or, better yet, just use rsync (more specifically its -z
flag).
