I'm not sure whether I understand correctly what you are writing; however, I 
suppose you are still at risk of data corruption.

If you have a VM running on an LV, and you have a _file_ inside that VM that 
contains large chunks of zeros, these zeros are indistinguishable from "empty" 
blocks. Thus, during restore, the respective blocks are not written, 
(possibly) resulting in garbage on disk -- and thus garbage in said file of 
the VM.

Try it.
