@davidep I had a much more successful restore. I actually installed file sharing and created a share before the backup, and the ad server was restored... this was pretty well confirmed because I had another member vm running that was joined, made a fresh backup of the ad vm, then destroyed it, started with a fresh vm with the current files in nethserver-testing installed (see screenshot, I see you made some changes with the available packages), While the fresh vm was updating I checked the member vm, it was lacking in any domain info as expected, once the restore was finished, the member vm then re-joined the ad server. Good.
But, a share I created... was not recreated, it does not exist in ibay, see error;

Also... I did not have nextcloud installed in this vm, but I did have that php_scl package installed... php was set for defaut (5.4), that package... as expected, was not re-installed.
I just want to make a note of this because we need to make sure that happens because down the road if we're using php scl to have nextcloud 11 running then obviously we'll want that environment restored properly as well.
