You can then easily initialize a repository that uses your Amazon S3 as
a backend. If the bucket does not exist it will be created in the

a backend. Make sure to use the endpoint for the correct region. The example
uses ``us-east-1``. If the bucket does not exist it will be created in that region:

If needed, you can manually specify the region to use by either setting the
environment variable ``AWS_DEFAULT_REGION`` or calling restic with an option
parameter like ``-o s3.region="us-east-1"``. If the region is not specified,
the default region is used. Afterwards, the S3 server (at least for AWS,
``s3.amazonaws.com``) will redirect restic to the correct endpoint.
When using temporary credentials make sure to include the session token via

Until version 0.8.0, restic used a default prefix of ``restic``, so the files
in the bucket were placed in a directory named ``restic``. If you want to

For an S3-compatible server that is not Amazon (like Minio, see below),

Virtual-hostedstyle URLs like ``bucket_name.s3.us-west-2.amazonaws.com``,
where the bucket name is part of the hostname are not supported. These must
be converted to path-style URLs instead, for example ``s3.us-west-2.amazonaws.com/bucket_name``.
.. note:: Certain S3-compatible servers do not properly implement the
``ListObjectsV2`` API, most notably Ceph versions before v14.2.5. On these
backends, as a temporary workaround, you can provide the
``-o s3.list-objects-v1=true`` option to use the older
``ListObjects`` API instead. This option may be removed in future

S3-compatible Storage
*********************
For an S3-compatible server that is not Amazon, you can specify the URL to the server
like this: ``s3:https://server:port/bucket_name``.
If needed, you can manually specify the region to use by either setting the
environment variable ``AWS_DEFAULT_REGION`` or calling restic with an option
parameter like ``-o s3.region="us-east-1"``. If the region is not specified,
the default region ``us-east-1`` is used.
To select between path-style and virtual-hosted access, the extended option
``-o s3.bucket-lookup=auto`` can be used. It supports the following values:
- ``auto``: Default behavior. Uses ``dns`` for Amazon and Google endpoints. Uses
``path`` for all other endpoints
- ``dns``: Use virtual-hosted-style bucket access
- ``path``: Use path-style bucket access
Certain S3-compatible servers do not properly implement the ``ListObjectsV2`` API,
most notably Ceph versions before v14.2.5. On these backends, as a temporary
workaround, you can provide the ``-o s3.list-objects-v1=true`` option to use the
older ``ListObjects`` API instead. This option may be removed in future versions
of restic.
Wasabi
************
******
`Wasabi <https://wasabi.com>`__ is a low cost Amazon S3 conformant object storage provider.
Due to its S3 conformance, Wasabi can be used as a storage provider for a restic repository.
S3 storage from `Wasabi <https://wasabi.com>`__ can be used as follows.
- Create a Wasabi bucket using the `Wasabi Console <https://console.wasabisys.com>`__.
- Determine the correct Wasabi service URL for your bucket `here <https://wasabi-support.zendesk.com/hc/en-us/articles/360015106031-What-are-the-service-URLs-for-Wasabi-s-different-regions->`__.
You must first setup the following environment variables with the
credentials of your Wasabi account.
- Determine the correct Wasabi service URL for your bucket `here <https://wasabi-support.zendesk.com/hc/en-us/articles/360015106031-What-are-the-service-URLs-for-Wasabi-s-different-regions->`__.
- Set environment variables with the necessary account credentials
.. code-block:: console
$ export AWS_ACCESS_KEY_ID=<YOUR-WASABI-ACCESS-KEY-ID>
$ export AWS_SECRET_ACCESS_KEY=<YOUR-WASABI-SECRET-ACCESS-KEY>
Now you can easily initialize restic to use Wasabi as a backend with
this command.
.. code-block:: console
$ ./restic -r s3:https://<WASABI-SERVICE-URL>/<WASABI-BUCKET-NAME> init
enter password for new repository:
enter password again:
created restic repository xxxxxxxxxx at s3:https://<WASABI-SERVICE-URL>/<WASABI-BUCKET-NAME>
Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is irrecoverably lost.

Alibaba Cloud (Aliyun) Object Storage System (OSS)
**************************************************
`Alibaba OSS <https://www.alibabacloud.com/product/object-storage-service>`__ is an
encrypted, secure, cost-effective, and easy-to-use object storage
service that enables you to store, back up, and archive large amounts
of data in the cloud.
S3 storage from `Alibaba OSS <https://www.alibabacloud.com/product/object-storage-service>`__ can be used as follows.
Alibaba OSS is S3 compatible so it can be used as a storage provider
for a restic repository with a couple of extra parameters.
- Determine the correct `Alibaba OSS region endpoint <https://www.alibabacloud.com/help/en/object-storage-service/latest/regions-and-endpoints>`__ - this will be something like ``oss-eu-west-1.aliyuncs.com``
- You'll need the region name too - this will be something like ``oss-eu-west-1``
You must first setup the following environment variables with the
credentials of your Alibaba OSS account.
- Determine the correct `Alibaba OSS region endpoint <https://www.alibabacloud.com/help/en/object-storage-service/latest/regions-and-endpoints>`__ - this will be something like ``oss-eu-west-1.aliyuncs.com``
- You will need the region name too - this will be something like ``oss-eu-west-1``
- Set environment variables with the necessary account credentials
.. code-block:: console
$ export AWS_ACCESS_KEY_ID=<YOUR-OSS-ACCESS-KEY-ID>
$ export AWS_SECRET_ACCESS_KEY=<YOUR-OSS-SECRET-ACCESS-KEY>
Now you can easily initialize restic to use Alibaba OSS as a backend with
this command.
.. code-block:: console
$ ./restic -o s3.bucket-lookup=dns -o s3.region=<OSS-REGION> -r s3:https://<OSS-ENDPOINT>/<OSS-BUCKET-NAME> init
enter password for new backend:
enter password again:
created restic backend xxxxxxxxxx at s3:https://<OSS-ENDPOINT>/<OSS-BUCKET-NAME>
Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is irrecoverably lost.
For example with an actual endpoint:
.. code-block:: console
$ restic -o s3.bucket-lookup=dns -o s3.region=oss-eu-west-1 -r s3:https://oss-eu-west-1.aliyuncs.com/bucketname init
$ restic -o s3.bucket-lookup=dns -o s3.region=<OSS-REGION> -r s3:https://<OSS-ENDPOINT>/<OSS-BUCKET-NAME> init
