Recover FindFace Multi and Its Data
---------------------------------------

To restore FindFace Multi and its data from the backup, do the following:

#. Download the installer file ``findface-*.run``.
#. Put the ``.run`` file into some directory on the designated host (for example, ``/home/username``).
#. From this directory, make the ``.run`` file executable. 

   .. note::
      Be sure to specify the actual file name instead of ``findface-*``.

   .. code::

      chmod +x findface-*.run

#. Execute the ``.run`` file.

   .. code::

      sudo ./findface-*.run

#. Go through the installation process as described :ref:`here <installer>`.

#. After you have finished the installation, to restore FindFace Multi, its data and configuration files, stop all FindFace Multi containers.

   .. code::

      cd /opt/findface-multi
      sudo docker-compose stop

#. Remove new configuration files and data generated and created by the installer and restore them from the backup.

   .. code::
    
      sudo rm -r /opt/findface-multi/configs/*
      sudo tar -xvf ~/configs.tar.gz -C /opt/findface-multi/
      sudo rm -r /opt/findface-multi/data/*
      sudo tar -xvf ~/data.tar.gz -C /opt/findface-multi/

#. Restart FindFace Multi containers.

   .. code::
      
      cd /opt/findface-multi
      sudo docker-compose up -d
