Packages
********
Note that if at any point the package you’re trying to use is outdated, you
always have the option to use an official binary from the restic project.
These are up to date binaries, built in a reproducible and verifiable way, that
you can download and run without having to do additional installation work.
Please see the :ref:`official_binaries` section below for various downloads.
Official binaries can be updated in place by using the ``restic self-update``
command.

Official Binaries
*****************
Stable Releases
===============
You can download the latest stable release versions of restic from the `restic
release page <https://github.com/restic/restic/releases/latest>`__. These builds
are considered stable and releases are made regularly in a controlled manner.
There's both pre-compiled binaries for different platforms as well as the source
code available for download. Just download and run the one matching your system.
On your first installation, if you desire, you can verify the integrity of your
downloads by testing the SHA-256 checksums listed in ``SHA256SUMS`` and verifying
the integrity of the file ``SHA256SUMS`` with the PGP signature in ``SHA256SUMS.asc``.
The PGP signature was created using the key (`0x91A6868BD3F7A907 <https://restic.net/gpg-key-alex.asc>`__):
::
pub 4096R/91A6868BD3F7A907 2014-11-01
Key fingerprint = CF8F 18F2 8445 7597 3F79 D4E1 91A6 868B D3F7 A907
uid Alexander Neumann <alexander@bumpern.de>
sub 4096R/D5FC2ACF4043FDF1 2014-11-01
Once downloaded, the official binaries can be updated in place using the
``restic self-update`` command (needs restic 0.9.3 or later):
.. code-block:: console
$ restic version
restic 0.9.3 compiled with go1.11.2 on linux/amd64
$ restic self-update
find latest release of restic at GitHub
latest version is 0.9.4
download file SHA256SUMS
download SHA256SUMS
download file SHA256SUMS
download SHA256SUMS.asc
GPG signature verification succeeded
download restic_0.9.4_linux_amd64.bz2
downloaded restic_0.9.4_linux_amd64.bz2
saved 12115904 bytes in ./restic
successfully updated restic to version 0.9.4
$ restic version
restic 0.9.4 compiled with go1.12.1 on linux/amd64
The ``self-update`` command uses the GPG signature on the files uploaded to
GitHub to verify their authenticity. No external programs are necessary.
.. note:: Please be aware that the user executing the ``restic self-update``
command must have the permission to replace the restic binary.
If you want to save the downloaded restic binary into a different file, pass
the file name via the option ``--output``.
Unstable Builds
===============
Another option is to use the latest builds for the master branch, available on
the `restic beta download site
<https://beta.restic.net/?sort=time&order=desc>`__. These too are pre-compiled
and ready to run, and a new version is built every time a push is made to the
master branch.
Windows
=======
On Windows, put the `restic.exe` binary into `%SystemRoot%\\System32` to use restic
in scripts without the need for absolute paths to the binary. This requires
administrator rights.
Docker Container
****************
We're maintaining a bare docker container with just a few files and the restic
binary, you can get it with `docker pull` like this:
.. code-block:: console
$ docker pull restic/restic
From Source
***********
restic is written in the Go programming language and you need at least
Go version 1.18. Building for Solaris requires at least Go version 1.20.
Building restic may also work with older versions of Go,
but that's not supported. See the `Getting
started <https://go.dev/doc/install>`__ guide of the Go project for
instructions how to install Go.
In order to build restic from source, execute the following steps:
.. code-block:: console
$ git clone https://github.com/restic/restic
[...]
$ cd restic
$ go run build.go
You can easily cross-compile restic for all supported platforms, just
supply the target OS and platform via the command-line options like this
(for Windows and FreeBSD respectively):
.. code-block:: console
$ go run build.go --goos windows --goarch amd64
$ go run build.go --goos freebsd --goarch 386
$ go run build.go --goos linux --goarch arm --goarm 6
$ go run build.go --goos solaris --goarch amd64
The resulting binary is statically linked and does not require any
libraries.
At the moment, the only tested compiler for restic is the official Go
compiler. Building restic with gccgo may work, but is not supported.
Autocompletion
**************
Restic can write out man pages and bash/fish/zsh/powershell compatible autocompletion scripts:
.. code-block:: console
$ ./restic generate --help
The "generate" command writes automatically generated files (like the man pages
and the auto-completion files for bash, fish, zsh and powershell).
Usage:
restic generate [flags] [command]
Flags:
--bash-completion file write bash completion file
--fish-completion file write fish completion file
-h, --help help for generate
--man directory write man pages to directory
--powershell-completion write powershell completion file
--zsh-completion file write zsh completion file
Example for using sudo to write a bash completion script directly to the system-wide location:
.. code-block:: console
$ sudo ./restic generate --bash-completion /etc/bash_completion.d/restic
writing bash completion file to /etc/bash_completion.d/restic
Example for using sudo to write a zsh completion script directly to the system-wide location:
.. code-block:: console
$ sudo ./restic generate --zsh-completion /usr/local/share/zsh/site-functions/_restic
writing zsh completion file to /usr/local/share/zsh/site-functions/_restic
.. note:: The path for the ``--bash-completion`` option may vary depending on
the operating system used, e.g. ``/usr/share/bash-completion/completions/restic``
in Debian and derivatives. Please look up the correct path in the appropriate
documentation.
