[TYPO3-english] Website Synchronisation

[Miguel]

Greetings,

I want to have a copy of my website in the same hosting package, the "main" website to show to the users, and the copy of the website only visible to me, so i can work, develop and test new features in the backup of the website. 

My question is if there is some extension that allows me to syncronize the new work created and "inject" these new changes directly to the main website.

If i not made my self clear, i will explain it better.

Kind regards
