Introduction
############
Restic is a fast and secure backup program. In the following sections, we will
present typical workflows, starting with installing, preparing a new
repository, and making the first backup.

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
.. note::
| A docker container is available as a contribution (Thank you!).

As you can see, restic created a backup of the directory and was pretty
fast! The specific snapshot just created is identified by a sequence of
hexadecimal characters, ``40dc1520`` in this case.
If you don't pass the ``--verbose`` option, restic will print less data (but
you'll still get a nice live status display).
If you run the command again, restic will create another snapshot of
your data, but this time it's even faster. This is de-duplication at
work!

@ -87,33 +132,53 @@ the exclude options are:
- ``--exclude-if-present`` Specified one or more times to exclude a folders content
if it contains a given file (optionally having a given header)
Basic example:
Let's say we have a file called ``excludes.txt`` with the following content:
.. code-block:: console
$ cat exclude
::
# exclude go-files
*.go
# exclude foo/x/y/z/bar foo/x/bar foo/bar
foo/**/bar
$ restic -r /tmp/backup backup ~/work --exclude="*.c" --exclude-file=exclude
It can be used like this:
.. code-block:: console
$ restic -r /srv/restic-repo backup ~/work --exclude="*.c" --exclude-file=excludes.txt
This instruct restic to exclude files matching the following criteria:
* All files matching ``*.go`` (second line in ``excludes.txt``)
* All files and sub-directories named ``bar`` which reside somewhere below a directory called ``foo`` (fourth line in ``excludes.txt``)
* All files matching ``*.c`` (parameter ``--exclude``)
Please see ``restic help backup`` for more specific information about each exclude option.
Patterns use `filepath.Glob <https://golang.org/pkg/path/filepath/#Glob>`__ internally,
see `filepath.Match <https://golang.org/pkg/path/filepath/#Match>`__ for syntax.
Patterns are tested against the full path of a file/dir to be saved, not only
against the relative path below the argument given to restic backup.
Patterns need to match on complete path components. (``foo`` matches
``/dir1/foo/dir2/file`` and ``/dir/foo`` but does not match ``/dir/foobar`` or
``barfoo``.) A trailing ``/`` is ignored. A leading ``/`` anchors the
pattern at the root directory. (``/bin`` matches ``/bin/bash`` but does not
match ``/usr/bin/restic``.) Regular wildcards cannot be used to match over the
directory separator ``/``. (``b*ash`` matches ``/bin/bash`` but does not match
``/bin/ash``.) However ``**`` matches arbitrary subdirectories. (``foo/**/bar``
matches ``/dir1/foo/dir2/bar/file``, ``/foo/bar/file`` and ``/tmp/foo/bar``.)
Environment-variables in exclude-files are expanded with
`os.ExpandEnv <https://golang.org/pkg/os/#ExpandEnv>`__.
see `filepath.Match <https://golang.org/pkg/path/filepath/#Match>`__ for

even if restic is passed a relative path to save. Environment-variables in
exclude-files are expanded with `os.ExpandEnv <https://golang.org/pkg/os/#ExpandEnv>`__.
Patterns need to match on complete path components. For example, the pattern ``foo``:
* matches ``/dir1/foo/dir2/file`` and ``/dir/foo``
* does not match ``/dir/foobar`` or ``barfoo``
A trailing ``/`` is ignored, a leading ``/`` anchors the
pattern at the root directory. This means, ``/bin`` matches ``/bin/bash`` but
does not match ``/usr/bin/restic``.
Regular wildcards cannot be used to match over the
directory separator ``/``. For example: ``b*ash`` matches ``/bin/bash`` but does not match
``/bin/ash``.
For this, the special wildcard ``**`` can be used to match arbitrary
sub-directories: The pattern ``foo/**/bar`` matches:
* ``/dir1/foo/dir2/bar/file``
* ``/foo/bar/file``
* ``/tmp/foo/bar``

Whenever a cache directory for a repo is used, that directory's modification
timestamp is updated to the current time. By looking at the modification
timestamps of the repo cache directories it is easy to decide which directories

Local Cache
===========
In order to speed up certain operations, restic manages a local cache of data.
This document describes the data structures for the local cache with version 1.
Versions
--------
The cache directory is selected according to the `XDG base dir specification
<http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>`__.
Each repository has its own cache sub-directory, consting of the repository ID
which is chosen at ``init``. All cache directories for different repos are
independent of each other.
The cache dir for a repo contains a file named ``version``, which contains a
single ASCII integer line that stands for the current version of the cache. If
a lower version number is found the cache is recreated with the current
version. If a higher version number is found the cache is ignored and left as
is.
Snapshots, Data and Indexes
---------------------------
Snapshot, Data and Index files are cached in the sub-directories ``snapshots``,
``data`` and ``index``, as read from the repository.
Expiry
------
Whenever a cache directory for a repo is used, that directory's modification
timestamp is updated to the current time. By looking at the modification
timestamps of the repo cache directories it is easy to decide which directories
are old and haven't been used in a long time. Those are probably stale and can
be removed.
