Installation
============

There are different ways to install Borg:

- :ref:`distribution-package` - easy and fast if a package is
  available from your distribution.
- :ref:`pyinstaller-binary` - easy and fast, we provide a ready-to-use binary file
  that comes bundled with all dependencies.
- :ref:`source-install`, either:

  - :ref:`windows-binary` - builds a binary file for Windows using MSYS2.
  - :ref:`pip-installation` - installing a source package with pip needs
    more installation steps and requires all dependencies with
    development headers and a compiler.
  - :ref:`git-installation`  - for developers and power users who want to
    have the latest code or use revision control (each release is
    tagged).

.. _distribution-package:

Distribution Package
--------------------

Some distributions might offer a ready-to-use ``borgbackup``
package which can be installed with the package manager.

.. important:: Those packages may not be up to date with the latest
               Borg releases. Before submitting a bug
               report, check the package version and compare that to
               our latest release then review :doc:`changes` to see if
               the bug has been fixed. Report bugs to the package
               maintainer rather than directly to Borg if the
               package is out of date in the distribution.

.. _pyinstaller-binary:

Standalone Binary
-----------------

.. note:: Releases are signed with an OpenPGP key, see
          :ref:`security-contact` for more instructions.

Borg x86/x64 AMD/Intel compatible binaries (generated with `pyinstaller`_)
are available on the releases_ page for the following platforms:

* **Linux**: glibc >= 2.28 (ok for most supported Linux releases).
  Older glibc releases are untested and may not work.
* **macOS**: 10.12 or newer (To avoid signing issues, download the file via
  command line **or** remove the ``quarantine`` attribute after downloading:
  ``$ xattr -dr com.apple.quarantine borg-macosx64.tgz``)
* **FreeBSD**: 12.1 (unknown whether it works for older releases)

ARM binaries are built by Johann Bauer, see: https://borg.bauerj.eu/

.. note:: ``borg mount`` only works if the binary was built with FUSE support
          (third-party binaries might lack it) and your OS has FUSE installed
          (e.g. the ``fuse3`` package on Linux, macFUSE on macOS).
          If ``borg mount`` fails, the error message will tell for each FUSE
          implementation why it could not be loaded.

To install such a binary, just drop it into a directory in your ``PATH``,
make borg readable and executable for its users and then you can run ``borg``::

    sudo cp borg-linux64 /usr/local/bin/borg
    sudo chown root:root /usr/local/bin/borg
    sudo chmod 755 /usr/local/bin/borg

Optionally you can create a symlink to have ``borgfs`` available, which is an
alias for ``borg mount``::

    ln -s /usr/local/bin/borg /usr/local/bin/borgfs

Note that the binary uses /tmp to unpack Borg with all dependencies. It will
fail if /tmp has not enough free space or is mounted with the ``noexec``
option. You can change the temporary directory by setting the ``TEMP``
environment variable before running Borg.

If a new version is released, you will have to download it manually and replace
the old version using the same steps as shown above.

.. _source-install:

From Source
-----------

.. note::

  Some older Linux systems (like RHEL/CentOS 5) and Python interpreter binaries
  compiled to be able to run on such systems (like Python installed via Anaconda)
  might miss functions required by Borg.

  This issue will be detected early and Borg will abort with a fatal error.

Dependencies
~~~~~~~~~~~~

To install Borg from a source package (including pip), you have to install the
following dependencies first. For the libraries you will also need their
development header files (sometimes in a separate `-dev` or `-devel` package).

* `Python 3`_ >= 3.11.0
* OpenSSL_ >= 1.1.1 (LibreSSL will not work)
* libacl_ (which depends on libattr_)
* liblz4_ >= 1.7.0 (r129)
* libffi (required for argon2-cffi-bindings)
* pkg-config (cli tool) - Borg uses this to discover header and library
  locations automatically. Alternatively, you can also point to them via some
  environment variables, see setup.py.
* Some other Python dependencies, pip will automatically install them for you.
* Optionally, if you wish to mount an archive as a FUSE filesystem, you need
  a FUSE implementation for Python:

  - mfusepy_ >= 3.1.0 (for fuse 2 and fuse 3, use `pip install borgbackup[mfusepy]`), or
  - pyfuse3_ >= 3.1.1 (for fuse 3, use `pip install borgbackup[pyfuse3]`), or
  - llfuse_ >= 1.3.8 (for fuse 2, use `pip install borgbackup[llfuse]`).
  - Additionally, your OS will need to have FUSE support installed
    (e.g. a package `fuse` for fuse 2 or a package `fuse3` for fuse 3 support).
* Optionally, if you wish to use S3/B2 Backend:
  - borgstore[s3] ~= 0.3.0 (use `pip install borgbackup[s3]`)
* Optionally, if you wish to use SFTP Backend:
  - borgstore[sftp] ~= 0.3.0 (use `pip install borgbackup[sftp]`)

If you have troubles finding the right package names, have a look at the
distribution specific sections below or the Vagrantfile in the git repository,
which contains installation scripts for a number of operating systems.

In the following, the steps needed to install the dependencies are listed for a
selection of platforms. If your distribution is not covered by these
instructions, try to use your package manager to install the dependencies.

After you have installed the dependencies, you can proceed with steps outlined
under :ref:`pip-installation`.

Arch Linux
++++++++++

Install the runtime and build dependencies::

    pacman -S python python-pip python-virtualenv openssl acl lz4 base-devel
    pacman -S fuse2     # needed for llfuse
    pacman -S fuse3     # needed for pyfuse3

Note that Arch Linux specifically doesn't support
`partial upgrades <https://wiki.archlinux.org/title/Partial_upgrade>`__,
so in case some packages cannot be retrieved from the repo, run with ``pacman -Syu``.

Debian / Ubuntu
+++++++++++++++

Install the dependencies with development headers::

    sudo apt-get install python3 python3-dev python3-pip python3-virtualenv \
    libacl1-dev \
    libssl-dev \
    liblz4-dev \
    libffi-dev \
    build-essential pkg-config
    sudo apt-get install libfuse-dev fuse    # needed for llfuse
    sudo apt-get install libfuse3-dev fuse3  # needed for pyfuse3

In case you get complaints about permission denied on ``/etc/fuse.conf``: on
Ubuntu this means your user is not in the ``fuse`` group. Add yourself to that
group, log out and log in again.

Fedora
++++++

Install the dependencies with development headers::

    sudo dnf install python3 python3-devel python3-pip python3-virtualenv \
    libacl-devel \
    openssl-devel \
    lz4-devel \
    libffi-devel \
    pkgconf
    sudo dnf install gcc gcc-c++ redhat-rpm-config
    sudo dnf install fuse-devel fuse         # needed for llfuse
    sudo dnf install fuse3-devel fuse3       # needed for pyfuse3

openSUSE Tumbleweed / Leap
++++++++++++++++++++++++++

Install the dependencies automatically using zypper::

    sudo zypper source-install --build-deps-only borgbackup

Alternatively, you can enumerate all build dependencies in the command line::

    sudo zypper install python3 python3-devel \
    libacl-devel openssl-devel liblz4-devel \
    libffi-devel \
    python3-Cython python3-Sphinx python3-msgpack-python python3-pkgconfig pkgconf \
    python3-pytest python3-setuptools python3-setuptools_scm \
    python3-sphinx_rtd_theme gcc gcc-c++
    sudo zypper install python3-llfuse  # llfuse

macOS
+++++

When installing borgbackup via Homebrew_, the basic dependencies are installed automatically.

For FUSE support to mount the backup archives, you need macFUSE, which is available
via `github <https://github.com/osxfuse/osxfuse/releases/latest>`__, or Homebrew::

    brew install --cask macfuse

When installing Borg via ``pip``, be sure to install the ``llfuse`` extra,
since macFUSE only supports FUSE API v2. Also, since Homebrew won't link
the installed ``openssl`` formula, point pkg-config to the correct path::

    PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig" pip install borgbackup[llfuse]

When working from a borg git repo workdir, you can install dependencies using the
Brewfile::

    brew install python@3.11  # can be any supported python3 version
    brew bundle install  # install requirements from borg repo's ./Brewfile
    pip3 install virtualenv

Be aware that for all recent macOS releases you must authorize full disk access.
It is no longer sufficient to run borg backups as root. If you have not yet
granted full disk access, and you run Borg backup from cron, you will see
messages such as::

    /Users/you/Pictures/Photos Library.photoslibrary: scandir: [Errno 1] Operation not permitted:

To fix this problem, you should grant full disk access to cron, and to your
Terminal application. More information `can be found here
<https://osxdaily.com/2020/04/27/fix-cron-permissions-macos-full-disk-access/>`__.

FreeBSD
++++++++

Listed below are packages you will need to install Borg, its dependencies,
and commands to make FUSE work for using the mount command.

::

     pkg install -y python3 pkgconf
     pkg install openssl
     pkg install liblz4
     pkg install fusefs-libs  # needed for llfuse
     pkg install -y git
     python3 -m ensurepip # to install pip for Python3
     To use the mount command:
     echo 'fuse_load="YES"' >> /boot/loader.conf
     echo 'vfs.usermount=1' >> /etc/sysctl.conf
     kldload fuse
     sysctl vfs.usermount=1

.. _windows_deps:

Windows
+++++++

.. note::
    Running under Windows is experimental.

.. warning::
    This script needs to be run in the UCRT64 environment in MSYS2.

Install the dependencies with the provided script::

    ./scripts/msys2-install-deps

.. _msys2_path_translation:

MSYS2 Path Translation
++++++++++++++++++++++

When running Borg within an MSYS2 environment, the shell
automatically translates POSIX-style paths (like ``/tmp`` or ``/C/Users``) to
Windows paths (like ``C:\msys64\tmp`` or ``C:\Users``) before they reach the
Borg process.

This behavior can result in absolute Windows paths being stored in your backups,
which may not be what you intended if you use POSIX paths for portability.

To disable this automatic translation for Borg, you can use environment variables
to exclude everything from conversion. Similarly, MSYS2 also translates
environment variables that look like paths. To disable this generally for Borg,
set both variables::

    export MSYS2_ARG_CONV_EXCL="*"
    export MSYS2_ENV_CONV_EXCL="*"

For more details, see the `MSYS2 documentation on filesystem paths <https://www.msys2.org/docs/filesystem-paths/>`__.

Windows 10's Linux Subsystem
++++++++++++++++++++++++++++

.. note::
    Running under Windows 10's Linux Subsystem is experimental and has not been tested much yet.

Just follow the Ubuntu Linux installation steps. You can omit the FUSE stuff, it won't work anyway.


Cygwin
++++++

.. note::
    Running under Cygwin is experimental and has not been tested much yet.

Use the Cygwin installer to install the dependencies::

    python39 python39-devel
    python39-setuptools python39-pip python39-wheel python39-virtualenv
    libssl-devel liblz4-devel
    binutils gcc-g++ git make openssh

Make sure to use a virtual environment to avoid confusions with any Python installed on Windows.

.. _windows-binary:

Building a binary on Windows
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. note::
    This is experimental.

.. warning::
    This needs to be run in the UCRT64 environment in MSYS2.

Ensure to install the dependencies as described within :ref:`Dependencies: Windows <windows_deps>`.

::

    # Needed for setuptools < 70.2.0 to work - https://www.msys2.org/docs/python/#known-issues
    # export SETUPTOOLS_USE_DISTUTILS=stdlib
    pip install -e .
    pyinstaller -y scripts/borg.exe.spec

A standalone executable will be created in ``dist/borg.exe``.

.. _pip-installation:

Using pip
~~~~~~~~~

Virtualenv_ can be used to build and install Borg without affecting
the system Python or requiring root access.  Using a virtual environment is
optional, but recommended except for the most simple use cases.

Ensure to install the dependencies as described within :ref:`source-install`.

.. note::
    If you install into a virtual environment, you need to **activate** it
    first (``source borg-env/bin/activate``), before running ``borg``.
    Alternatively, symlink ``borg-env/bin/borg`` into some directory that is in
    your ``PATH`` so you can run ``borg``.

This will use ``pip`` to install the latest release from PyPi::

    virtualenv --python=python3 borg-env
    source borg-env/bin/activate

    # might be required if your tools are outdated
    pip install -U pip setuptools wheel

    # install Borg + Python dependencies into virtualenv
    pip install borgbackup
    # or alternatively (if you want FUSE support):
    pip install borgbackup[llfuse]  # to use llfuse
    pip install borgbackup[pyfuse3]  # to use pyfuse3

To upgrade Borg to a new version later, run the following after
activating your virtual environment::

    pip install -U borgbackup  # or ... borgbackup[llfuse/pyfuse3]

When doing manual pip installation, man pages are not automatically
installed.  You can run these commands to install the man pages
locally::

    # get borg from github
    git clone https://github.com/borgbackup/borg.git borg

    # Install the files with proper permissions
    install -D -m 0644 borg/docs/man/borg*.1* $HOME/.local/share/man/man1/borg.1

    # Update the man page cache
    mandb

.. _git-installation:

Using git
~~~~~~~~~

This uses latest, unreleased development code from git.
While we try not to break master, there are no guarantees on anything.

Ensure to install the dependencies as described within :ref:`source-install`.

Version metadata is obtained dynamically at install time using ``setuptools-scm``.
Please ensure that your git repo either has correct tags, or provide the version
manually using the ``SETUPTOOLS_SCM_PRETEND_VERSION`` environment variable.

::

    # get borg from github
    git clone https://github.com/borgbackup/borg.git

    # create a virtual environment
    virtualenv --python=$(which python3) borg-env
    source borg-env/bin/activate   # always before using!

    # install borg dependencies into virtualenv
    cd borg
    pip install -r requirements.d/development.lock.txt
    pip install -r requirements.d/docs.txt  # optional, to build the docs

    # set a borg version if setuptools-scm fails to do so automatically
    export SETUPTOOLS_SCM_PRETEND_VERSION=

    # install borg into virtualenv
    pip install -e .           # in-place editable mode
    or
    pip install -e .[pyfuse3]  # in-place editable mode, use pyfuse3
    or
    pip install -e .[llfuse]   # in-place editable mode, use llfuse

    # optional: run all the tests, on all installed Python versions
    # requires fakeroot, available through your package manager
    fakeroot -u tox --skip-missing-interpreters

By default the system installation of python will be used.
If you need to use a different version of Python you can install this using ``pyenv``:

::

    ...
    # create a virtual environment
    pyenv install 3.11.0  # minimum, preferably use something more recent!
    pyenv global 3.11.0
    pyenv local 3.11.0
    virtualenv --python=${pyenv which python} borg-env
    source borg-env/bin/activate   # always before using!
    ...

.. note:: As a developer or power user, you should always use a virtual environment.
