Custom Mount Configuration (GUI)
================================

ownCloud provides the ability to mount an external storage device.
The external storage devices serves as a secondary storage device within ownCloud.

The ownCloud Admin has the ability to create such a mount.
In addition, the ownCloud Admin may decide to provide the end user the ability to create the mount.
The mounts may be created on a per-user, per group, or all user basis.

.. note:: Using ``$user`` in any option gets replaced by the current user. This can be used e.g to
	  specify users' own paths easily by just writing ``/home/$user/``.

Configure mounts
----------------

As stated previously, the Admin has the ability to configure these mounts, as
well as decide whether an end user can configure mounts for themselves.  For
the Admin, the configuration is performed in the ``Admin`` page.  For end
users, the configuration is performed in the ``Personal`` Page.  This document
will discuss how the Admin configures the mounts, however, the configuration is
the same for the end user.

On the ``Admin`` page, scroll to External Storage:

Configuration File
------------------

The configuration of mounts created within the External Storage App are stored in the
``data/mount.json`` file.
This file contains all settings in JSON (JavaScript Object Notation) format.
Two different types of entries exist:

*   Group mounts -
    Each entry configures a mount for each user in group
*   User mount – Each entry configures a mount for a single user or all users.

For each type, there is a JSON array with the user/group name as key and an array of configuration values as the value.
Each entry consist of the class name of the storage backend and an array of backend specific options (described above) and will be replaced by the user login.

Although configuration may be done by making modifications to the mount.json file, it is recommended to use the Web-GUI in the administrator panel (as described in the above section) to add, remove, or modify mount options in order to prevent any problems.
