You work hard at trying to do a good thing which makes me want to be 
helpful.  Using tar (see response below) can help manage a smaller 
window.

Which indicates that you have a time value synchronization issue 
between the two hosts and why you need to setup ntpd processes on the 
two hosts.  Note, I am not talking about timezones which gives local 
representation of time.  I am talking about the time value and there is 
only one (or should be) of those.

Yes, that is what I mean.  You can exclude[1] the settings.php file or 
the entire sites directory and any other file or directory you wish.  
The site maintenance is controlled in the DB via admin/settings and 
opening ``Site maintenance''.

You can always install a pristine set of files somewhere on the disk 
and use the diff command to find the changes.  If you want a GUI visual 
I suggest gvim[1].
