Now, if I were to create my snapshots on a seperate vg, eg:
You can't do that. Snapshots must be on the same VG. James is
suggesting you
create them on the same VG, but a different PV reserved for backup
snapshots.
Guess I need to go back to LVM basics. I had a "hierarchical" structure
in my head (which must be wrong):
An LV sites on top of a VG which sits on top of a PV
But going by your comment above, you can add multiple PVs (Physical
partitions) to a single VG and create some form of a JBOD configuration?
