Oh - in that case I've been emphasizing the fact, that lvm2 will not REMOVE,
those. So nothing in the sense it will keep creating if they get missing :) so 
something completely different.

If the admin runs  'rm -f /etc/lvm/archive/*' all archives are simply gone.
(so i.e. info about executed command is lost forever! as the kernel does not 
hold all the info)

> So the whole thing is about PV metadata area and not /etc/lvm , am I correct?

Vise versa -    /etc/lvm/lvm.conf { backup/archive = 1 }  is purely about 

There is *NO* control for user to influence PV metadata backup other then 
limiting the size of metadata area - the smalller the area is - the smaller 
'ring-buffer' will be - the less older metadata could be found there.
