Assuming you have checked projects like 'snapper' ?

We do not advice/support any user to use device on top of filesystem on top 
another device - this is only good as a 'toy' - never for anything serious - 
it has numerous troubles and the noticeable slower performance is
one the easy one...

With thin-snapshot - each snapshot as just another 'thin' device - so it 
doesn't really matter what is origin.
You can easily chain snapshot over snapshot over snapshot....
