Hm... 
Another no good approach.
In this way I loose everything appens to disk between the moment in
which I take the snap and the time in which dd end. I think at least 6/7
hours.

The good and most secure way is to mirror disks. In this way all blocks
are replicated, all I/O are replicated and disks are syncronized when I
shutdown the OS.

I will shutdown in a few moments and start an offline dd. Is the last
chance.
I hope it end fast

Bye
