You can already do this with GEOM.
On your server node, create a sparse file using dd, that is the same
size or bigger than the partition you would like to back up. Then set
it up with ggated. Now, on your machine with the partition that needs
mirroring (backing up), use ggatec to connect to the backup node's
shared sparse file you previously created. Then, use gmirror to mirror
your partition to the now local ggatec'ed device.
