Alexander Neumann f99c95c766 archiver: Fix intermediate index upload
A user discovered[1] that when the backup finishes during the upload of
an intermediate index, the upload is cancelled and the index never fully
saved, but the snapshot is saved and the backup finalizes without an
error. This lead to a situation where a snapshot references data that is
contained in the repo, but not referenced in any index, leading to
strange error messages.

This commit uses a dedicated context to signal the intermediate index
uploading routine to terminate after the last index has been uploaded.
This way, an upload running when the backup finishes is completed before
the routine terminates and the snapshot is saved.

Introduction
------------

restic is a backup program that is fast, efficient and secure.

For detailed usage and installation instructions check out the `documentation <https://restic.readthedocs.io/en/latest>`__.

You can ask questions in our `Discourse forum <https://forum.restic.net>`__.

Quick start
-----------

Once you've `installed
<https://restic.readthedocs.io/en/latest/020_installation.html>`__ restic, start
off with creating a repository for your backups:

.. code-block:: console

    $ restic init --repo /tmp/backup
    enter password for new backend:
    enter password again:
    created restic backend 085b3c76b9 at /tmp/backup
    Please note that knowledge of your password is required to access the repository.
    Losing your password means that your data is irrecoverably lost.

and add some data:

.. code-block:: console

    $ restic -r /tmp/backup backup ~/work
    enter password for repository:
    scan [/home/user/work]
    scanned 764 directories, 1816 files in 0:00
    [0:29] 100.00%  54.732 MiB/s  1.582 GiB / 1.582 GiB  2580 / 2580 items  0 errors  ETA 0:00
    duration: 0:29, 54.47MiB/s
    snapshot 40dc1520 saved

Next you can either use ``restic restore`` to restore files or use ``restic
mount`` to mount the repository via fuse and browse the files from previous
snapshots.

For more options check out the `online documentation <https://restic.readthedocs.io/en/latest/>`__.

Backends
--------

Saving a backup on the same machine is nice but not a real backup strategy.
Therefore, restic supports the following backends for storing backups natively:

- `Local directory <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#local>`__
- `sftp server (via SSH) <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#sftp>`__
- `HTTP REST server <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server>`__ (`protocol <doc/100_references.rst#rest-backend>`__ `rest-server <https://github.com/restic/rest-server>`__)
- `AWS S3 <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#amazon-s3>`__ (either from Amazon or using the `Minio <https://minio.io>`__ server)
- `OpenStack Swift <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#openstack-swift>`__
- `BackBlaze B2 <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#backblaze-b2>`__
- `Microsoft Azure Blob Storage <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#microsoft-azure-blob-storage>`__
- `Google Cloud Storage <https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#google-cloud-storage>`__

Design Principles
-----------------

Restic is a program that does backups right and was designed with the
following principles in mind:

-  **Easy:** Doing backups should be a frictionless process, otherwise
   you might be tempted to skip it. Restic should be easy to configure
   and use, so that, in the event of a data loss, you can just restore
   it. Likewise, restoring data should not be complicated.

-  **Fast**: Backing up your data with restic should only be limited by
   your network or hard disk bandwidth so that you can backup your files
   every day. Nobody does backups if it takes too much time. Restoring
   backups should only transfer data that is needed for the files that
   are to be restored, so that this process is also fast.

-  **Verifiable**: Much more important than backup is restore, so restic
   enables you to easily verify that all data can be restored.

-  **Secure**: Restic uses cryptography to guarantee confidentiality and
   integrity of your data. The location the backup data is stored is
   assumed not to be a trusted environment (e.g. a shared space where
   others like system administrators are able to access your backups).
   Restic is built to secure your data against such attackers.

-  **Efficient**: With the growth of data, additional snapshots should
   only take the storage of the actual increment. Even more, duplicate
   data should be de-duplicated before it is actually written to the
   storage back end to save precious backup space.

Reproducible Builds
-------------------

The binaries released with each restic version starting at 0.6.1 are
`reproducible <https://reproducible-builds.org/>`__, which means that you can
easily reproduce a byte identical version from the source code for that
release. Instructions on how to do that are contained in the
`builder repository <https://github.com/restic/builder>`__.
