I don't know why you make this point, as, at least in this thread,
the target of the backup is not mentioned and is trivial to have it
point to another system.
I wasn't aware LVM could create a snapshot which puts a complete copy
of the volume on another disk. In fact, AUIU, a snapshot doesn't
actually copy the whole volume, it creates a COW setup which saves any
blocks subsequently written to.
Exactly. So you put the LVM into a snapshot state, and "backup off the
snapshot, nice and clean then destroy the snapshot when finished".
