If the service account used with restic does not have the storage.buckets.get permission (in the "Storage Admin" role), Create cannot use Get to determine if the bucket is accessible. Rather than always trying to create the bucket on Get error, gracefully fall back to assuming the bucket is accessible. If it is, restic init will complete successfully. If it is not, it will fail on a later call. Here is what init looks like now in different cases. Service account without "Storage Admin": Bucket exists and is accessible (this is the case that didn't work before): $ ./restic init -r gs:this-bucket-does-exist:/ enter password for new backend: enter password again: created restic backend c02e2edb67 at gs:this-bucket-does-exist:/ Please note that knowledge of your password is required to access the repository. Losing your password means that your data is irrecoverably lost. Bucket exists but is not accessible: $ ./restic init -r gs:this-bucket-does-exist:/ enter password for new backend: enter password again: create key in backend at gs:this-bucket-does-exist:/ failed: service.Objects.Insert: googleapi: Error 403: my-service-account@myproject.iam.gserviceaccount.com does not have storage.objects.create access to object this-bucket-exists/keys/0fa714e695c8ecd58cb467cdeb04d36f3b710f883496a90f23cae0315daf0b93., forbidden Bucket does not exist: $ ./restic init -r gs:this-bucket-does-not-exist:/ create backend at gs:this-bucket-does-not-exist:/ failed: service.Buckets.Insert: googleapi: Error 403: my-service-account@myproject.iam.gserviceaccount.com does not have storage.buckets.create access to bucket this-bucket-does-not-exist., forbidden Service account with "Storage Admin": Bucket exists and is accessible: Same Bucket exists but is not accessible: Same. Previously this would fail when Create tried to create the bucket. Now it fails when trying to create the keys.

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