Thanks for your answer,
You are right.
Now I'm doing a test for verifie a parameter that you wrote me.
In particular: ctime, size, owner and group with "ls -la" and "du -s".
But I don't see any change.
Do you think is possible that the "parameter" changed when the "tar" 
process was ran?

I ask you this becasue in the normal situation (the tar process don't 
run)I haven't seen change (when write "ls -la" and "ds -s" ).

In the next mail I post the logs of my test.

Thanks Alessandro
