After restore there are no logs on existent nodes in Nailgun UI.
In /var/log/docker-logs/remote they exists and have access by ip addr.
Move logs from ip addr path to FQDN path and create symlink ip
addr path to fqdn path.
If ip addr path doesn't exists create empty fqdn path dir and create
link to it with ip addr path name to this directory.
