When it comes to backup/restore there are many cost effective solutions, like:
If you lose one of the 2 DC's in each site you can just recover the domain using the other server, then rebuild a new DC and add it back in:
I think the concern that is unexpressed in your case, regarding protecting your domain itself falls into the category of Disaster Recovery. The most cost effective way that I know of is to use Azure Site Recovery: https://azure.microsoft.com/en-us/services/site-recovery/
Consider what you scenario that you are trying to protect for. (i.e. consider if the 2 sites are far enough apart to act as DR sites for each other. Meaning if one site is destroyed, the other site will be used to recover the domain as described above.) -->

A full server backup is recommended to prepare for a forest recovery because it can be restored to different hardware or a different operating system instance. Using Windows Server Backup you can perform a full backup of your server.
Windows Server Backup
Windows Server Backup is not installed by default. In Windows Server 2016 and Windows Server 2012 R2, install it by following the steps below.
Note
Please be aware that the steps may vary slightly between Windows Server 2016 and Windows Server 2012 R2.
For steps to install it in Windows Server 2008 and Windows Server 2008 R2, see Installing Windows Server Backup.

Note
If you get an error stating that no backup storage location is available, you will need to either exclude one of the volumes that has been selected or add a new volume or remote share.If you get a warning stating that the selected volume is also included in the list of items to backup, determine whether or not to remove and click Ok.

I have a Windows Server 2012 Essentials server at home I am about to update to 2012 R2.According to MS it is not possible to do an in-place upgrade and I am required to make a clean installation of R2. That is not really a problem except I would like to 'keep my users' to avoid the troubles of giving new passwords to all my familiy members and a few friends with remote access..
So I thought there would be an easy way to back up the users from the AD, but I did not find any..
Does someone know a tool to back up and restore users from an AD-Domain?
P.S.: I have a VMWare ESXi box here so if there is a way with a second temporary VM that would also work for me, but AFAIK does WS2k12 Essentials allways create a new AD on installation or only can update an old WS2k12E (which I can't do, as I want to install it on the same HW)..

I haven't done an installation of Windows Server 2012 R2 Essentials into an existing Windows Server 2012 AD domain, but I just did an install into a Windows Server 2003 AD domain last week and it worked fine. I was able to join the existing domain, promote my W2K12 R2 Essentials machine to a DC, and then retire the existing Windows Server 2003 DC. It worked out just fine.
Were I in your situation I'd:
I'd mock this up with VMs before I actually did it, just to be sure it all worked smoothly in real life. It looks like a solid plan to me.
I wouldn't do any kind of 'backup / restore' of AD, or any type of AD migration. Using AD's existing replication functionality is the way to handle this problem.

Active Directory Domain Services provide functions for backing up and restoring data in the directory database. This section describes how to back up and restore an Active Directory server. For more information about backing up an Active Directory server using the utilities provided in Windows 2000 and Windows Server 2003 operating systems, see the applicable Resource Kit, available on the Microsoft TechNet website.
Backup of an Active Directory server must be performed online and must be performed when the Active Directory Domain Services are installed. Active Directory Domain Services are built on a special database and export a set of backup functions that provide the programmatic backup interface. The backup does not support incremental backups. A backup application binds to a local client-side DLL with entry points defined in Ntdsbcli.h.
Restoration of an Active Directory server is always performed offline.
Although the topics in this section describe only how to back up and restore an Active Directory server, be aware that Windows 2000 and the Windows Server 2003 operating systems have several 'system state' components that must be backed up and restored together. These system state components consist of:
The system state can be backed up in any order, but restoration of the system state must occur in the following order:
