Thank you ragdata,
JoomlaPack seems to meet all my needs, i will try him and report feedback later in this thread.
The following is extracted from the official site, from the "why to use" section:
Move your site between hosts. Do you want to move your site to a new hosting service? Would you like to set up a staging site, an exact clone of your live site where you can test new components and layouts? Do you want to debug a site without putting it offline? JoomlaPack comes to your rescue! With its renowned technology it is able to restore your site on a different host than the one the backup was taken from, even on a different platform (e.g. from a Linux host running Apache to a Windows Server host running IIS).
Regards
