# Custom Mount Configuration

Since ownCloud 4.0 it is possible to configure the filesystem to mount external storage providers into ownCloud’s virtual file system. You can configure these file systems by creating and editing `data/mount.json`. This file contains all settings in JSON (JavaScript Object Notation) format. At the moment two different types of entries exist:

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

For each type, there is a JSON array with the user/group name as key, and an array of configuration entries as value. Each entry consist of the class name of the storage backend and an array of backend specific options and will be replaced by the user login. The template $user can be used in the mount point or backend options. As of writing the following storage backends are available for use:

- Local file system
- FTP (or FTPS)
- SFTP
- SMB
- WebDAV
- Amazon S3
- Dropbox
- Google Drive
- OpenStack Swift

Please keep in mind that some formatting has been applied and carriage returns have been added for better readability. In the `data/mount.json` all values need to be concatenated and written in a row without these modifications!

It is recommended to use the Web-GUI in the administrator panel to add, remove or modify mount options to prevent any problems!

## Example

    {"group":{
        "admin":{
            "\/$user\/files\/Admin_Stuff":{
                "class":"\\OC\\Files\\Storage\\Local",
                "options":{ ... }
                }
            }
        }
     "user":{
        "all":{
            "\/$user\/files\/Pictures":{
                "class":"\\OC\\Files\\Storage\\DAV",
                "options":{ ... }
                }
            }
        "someuser":{
            "\/someuser\/files\/Music":{
                "class":"\\OC\\Files\\Storage\\FTP",
                "options":{ ... }
                }
            }
        }
    }

## Backends

### Local Filesystem

The local filesystem backend mounts a folder on the server into the virtual filesystem, the class to be used is \OC\Files\Storage\Local and takes the following options:

- datadir : the path to the local directory to be mounted

#### Example

    { "class":"\\OC\\Files\\Storage\\Local",
      "options":{ "datadir":"\/mnt\/additional_storage" }
    }

Note

You must ensure that the web server has sufficient permissions on the folder.

### FTP (or FTPS)

The FTP backend mounts a folder on a remote FTP server into the virtual filesystem and is part of the ‘External storage support’ app, the class to be used is \OC\Files\Storage\FTP and takes the following options:

- host: the hostname of the ftp server
- user: the username used to login on the ftp server
- password: the password to login on the ftp server
- secure: whether to use ftps:// (FTP over TLS) to connect to the ftp server instead of ftp:// (optional, defaults to false)
- root: the folder inside the ftp server to mount (optional, defaults to ‘/’)

#### Example

    {   "class":"\\OC\\Files\\Storage\\FTP",
        "options":{
            "host":"ftp.myhost.com",
            "user":"johndoe",
            "password":"secret",
            "root":"\/Videos",
            "secure":"false"
        }
    }

Note

PHP needs to be build with FTP support for this backend to work.

### SFTP

The SFTP backend mounts a folder on a remote SSH server into the virtual filesystem and is part of the ‘External storage support’ app. The class to be used is \OC\Files\Storage\SFTP and takes the following options:

- host: the hostname of the SSH server

- password: the password to login on the SSH server
- root: the folder inside the SSH server to mount (optional, defaults to ‘/’)

#### Example

    {   "class":"\\OC\\Files\\Storage\\SFTP",
        "options":{
            "host":"ssh.myhost.com",
            "user":"johndoe",
            "password":"secret",
            "root":"\/Books"
        }
    }

Note

PHP needs to be build with SFTP support for this backend to work.
