It seems I looked too coarsly. It showed all the files to restore. Then it show the same files…but to delete. So I ran it again but cancelled as soon as it began deleting. Now I have a system that boots at leasr into tty and can try to restore /home with duplicacy from there.

Still the question remains why everything was set to be deleted after restoring.

Thanks. I did not snapshot the home folder. I tried to restore a snapshot of a working system but got a wiped ssd instead.
