Setup Network Folder
--------------------

.. note:: This guide is for Ubuntu only.  For Linux Mint, click on "Mint", or for different distros such as Arch, Debian, Pop-OS, PureOS, etc, click "Other Linux" below.

    .. group-tab:: Ubuntu

        Check out the video below, and follow along with the steps in this guide to setup a network folder on your Linux machine, such that you may create encrypted, private backups of all your Embassy data.

        #. Install Samba if you have not already:

            .. code-block::

                sudo apt install samba && sudo systemctl enable smbd

        #. Add your user to samba, replacing ``YOUR_LINUX_USERNAME`` with your Linux username.

            .. code-block:: bash

                sudo smbpasswd -a YOUR_LINUX_USERNAME

            First you will be prompted for your linux password, then you will be asked to create a new SMB password for the user with permission to write to your new backup share.  Keep it somewhere safe, such as Vaultwarden.

        #. Right-click the folder that you want to backup to (or create a new one) and click "Properties"

            .. figure:: /_static/images/cifs/cifs-lin0.png

        #. Select the "Local Network Share" tab

        #. Click "Share this folder"

            .. figure:: /_static/images/cifs/cifs-lin2.png
                :width: 60%

            - You may rename the "Share", if you prefer - **remember this name**, you will need it later in your EmbassyUI

            - (Optional) Create a description in the "Comment" section

        #. Check the box for "Allow others to create and delete files in this folder", then click "Create Share"

        #. Install Samba if you have not already:

            .. code-block::

                sudo apt install samba && sudo systemctl enable smbd

        #. Add your user to samba, replacing ``YOUR_LINUX_USERNAME`` with your Linux username.

            .. code-block:: bash

                sudo usermod -a -G sambashare YOUR_LINUX_USERNAME
                sudo smbpasswd -a YOUR_LINUX_USERNAME

            First you will be prompted for your linux password, then you will be asked to create a new SMB password for the user with permission to write to your new backup share.  Keep it somewhere safe, such as Vaultwarden.

        #. Right-click the folder that you want to backup to (or create a new one, eg. ``embassy-backup``) and click "Sharing Options"

        #. Enter a Share name consisting of 12 or fewer characters and click "Create Share"

            .. figure:: /_static/images/cifs/cifs-mint1.png
                :width: 60%

            - You may rename the "Share", if you prefer - **remember this name**, you will need it later in your EmbassyUI.  In this example, we call it ``backup-share``

            - (Optional) Create a description in the "Comment" section

        #. Install Samba if it is not already installed.

            * ``sudo pacman -S samba``                                      For Arch
            * ``sudo apt install samba``                                    For Debian-based distros (Pop-OS, PureOS, etc)
            * ``sudo yum install samba``                                    For CentOS/Redhat
            * ``sudo dnf install samba``                                    For Fedora

        #. Create a directory to share or choose an existing one and make note of its location (path).  For this example, we will call the share ``backup-share`` and its corresponding shared directory will be located at ``/home/user/embassy-backup``

        #. Configure Samba by adding the following to the end of the ``/etc/samba/smb.conf`` file:

            .. code-block::

                [backup-share]
                    path = "/home/user/embassy-backup"
                    create mask = 0600
                    directory mask = 0700
                    read only = no
                    guest ok = no

            Where:

            - ``[backup-share]`` is the *Share Name*, or title of the entry, and can be called anything you'd like
            - ``path`` should be the path to the directory you created earlier

            Copy the remainder of the entry exactly as it is

        #. Open a terminal and enter the following command, replacing ``YOUR-USER`` with your Linux username:

                .. code-block:: bash

                    sudo smbpasswd -a YOUR-USER

                This creates a password for the Local Network Share.  Keep it somewhere safe, such as Vaultwarden.


Connect Embassy
---------------

#. Go to *Embassy > Create Backup*.

    .. figure:: /_static/images/config/embassy_backup.png
        :width: 60%

#. Click "Open".

    .. figure:: /_static/images/config/embassy_backup0.png
        :width: 60%

#. Fill in the following fields:

    * Hostname - This is the hostname of the machine that your shared folder is located on
    * Path - This is the "Share Name" (name of the share in your samba config) and **not** the full directory path.  In this guide we used ``backup-share``
    * Username - This is your Linux username on the remote machine that you used to create the shared directory
    * Password - This is the password you set above using ``smbpasswd``

    .. figure:: /_static/images/config/embassy_backup1.png
        :width: 60%

#. Click "Save".

That's it!  You can now :ref:`Create<backup-create>` encrypted, private backups of all your Embassy data to your Linux machine or external drive!!
