Let's say I have a linux box, say RHES 4 or Centos 4, which I have
put everything but the boot partition in a LVM partition. Now I would like
to back it up. So, I could connect an external USB drive, then create the
snapshot LVM device and go from there. Now, let's say the disk I want to
snapshot to is in a different machine running the same OS. Is it possible
to somehow offer this disk to the first machine such that it can then
create its snapshot lvm target and then run the snapshot?
