You cannot "pull" a backup to a networked machine, NewtoMacs; you can only "push" a backup to an image stored on a network volume. That image can be stored on an external drive on "computer A", but you have to mount the image on "computer B" and perform the backup there.

It doesn't really matter if it's a data backup: the problem is that, given "native file format", we need to preserve ownership, and authorize to get access to all of the files in the mounted volume -- and you can't authorize like that across a network.

(Yes, you can get access to some files -- the ones owned by the user who logged in -- but that's typically not enough.)

Hope that helps. Remember: only the *image* needs to be mounted on the computer doing the backup. That image can be *hosted* on any computer on the network.
