Oh boy, I just read the mentioned thread and the problems that people had:
Bare Metal Restore using Remote Server Backup
Hope the procedure at the end works (hasnt been tested on the thread).
The backup/restore really makes sense when You can replace the hardware because it is old, disfunctional etc.
I have already activated all the subscriptions and made a 2gb backup to the cloud.
I will post the results here and on that thread, once (if) I restore.
I am planning a restore today not too late in the day (today is a special day, if I dont leave the office early enough, my wife will kill me)
