.. _Backing Up and Restoring Management Database:

Backing Up and Restoring Management Database
--------------------------------------------

|product_name| stores node information, statistics, and configuration in a database on the node with the management panel. Database backups are created automatically every day.

.. warning:: Do not rename the backup file! Otherwise you will not be able to restore the management database from it.

To back up the database manually, open the **SETTINGS** > **Backup** screen and click **BACKUP NOW**.

Once backup is completed, the **Last backup** date will be refreshed.

.. _Restoring Management Database from Backup:

Restoring Management Database from Backup
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can restore a management node database from backup on the following nodes:

- the same management node or any node assigned to a cluster,

- a new node outside the cluster. In this case, |product_name| will restore the database and install only the management panel component on the node.

To restore to the same management node or a cluster node, run the following script:

::

    # /usr/libexec/vstorage-ui-backend/bin/restore-management-node.sh \
    -x <public_network_interface> -i <private_network_interface>

where ``<public_network_interface>`` and ``<private_network_interface>`` are interfaces with already assigned public and internal roles. They will be assigned the **WebCP** and **Management** roles, respectively. 

.. note:: You can specify the same network interface in both parameters.

To restore the database to a new node, do the following:

#. Copy the backup file ``/mnt/vstorage/webcp/backup/backup-<timestamp>.tar`` from the initial management node to the same directory on the target node.

#. Run the following script on the target node:

   ::

       # /usr/libexec/vstorage-ui-backend/bin/restore-management-node.sh \
       -x <public_network_interface> -i <private_network_interface> \
       -f <path-to-backup-file>

   where ``<public_network_interface>`` and ``<private_network_interface>`` are interfaces to be assigned the **WebCP** and **Management** roles, respectively.
