It is hidden from the destination list in the user interface, see [deprecated and untested destinations](/backup-destinations/destination-overview.md#deprecated-and-untested-destinations). {% endhint %} Duplicati supports storing files on [Alibaba Cloud Object Storage Service](https://www.alibabacloud.com/en/product/object-storage-service), aka Aliyun OSS, which is a large-scale object storage, similar to S3. In Aliyun OSS you store "objects" (similar to files) in "buckets" which define various properties shared between the objects. If you use a `/` in the object prefix, they can be displayed as virtual folders when listing them. Note that the bucket id is globally unique, so it is recommended using a name that is not likely to conflict with other users, such as prefixing the bucket with the project id or a similar unique value. If you use a simple name, like `data` or `backup` it is likely already associated with another project and you will get permission errors when attempting to use it. ## User interface
Aliyun OSS destination configuration
To use the Aliyun OSS destination you must specify: bucket, path in bucket, access key id, access key secret, and endpoint. ## URL format for Commandline To use Aliyun OSS, you can use the following URL format: ``` aliyunoss:// ?oss-bucket-name= &oss-endpoint= &oss-access-key-id= &oss-access-key-secret= ``` The [endpoint is defined by Aliyun](https://www.alibabacloud.com/help/en/oss/user-guide/regions-and-endpoints) and needs to match the region the bucket is created it. The access key can be obtained or created in the Cloud Console. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.duplicati.com/backup-destinations/provider-specific-destinations/aliyun-oss-destination.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
