need to spend all organization unit folders, containing the names of all my users who log into their corresponding session, and restore it on another server that is also active directory domain server
If you're aiming to effectively stage an identical copy of you AD to a separate server (for testing or something) you can use the Group policy management console (GPMC) to export your entire domain to an xml file which you can import into a different AD. This will very effectively create a "copy" of all your OUs, GPOs, and even users/groups. Bear in mind, passwords are not migrated this way.
Language barriers aside, it is VERY important that you do not do this if you're trying to replace an old domain controller with a new one, or add a second domain controller to the same domain.
You'll find some sample scripts for GPMC-based exports here: http://www.microsoft.com/downloads/details.aspx?FamilyId=38C1A89B-A6D2-4F2A-A944-9236999AEE65&displaylang=en
If your newDC is in the same domain as the oldDC, then all the domain accounts will already be on the newDC.
If the newDC is in a different domain to oldDC, then you will need to use the Active Directory Migration Tool.
If you need to use the ADMT, let us know as there are some special requirements you need first (domain trusts, an account with Domain Admin privs in both domains etc)
