> For the complete documentation index, see [llms.txt](https://docs.duplicati.com/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.duplicati.com/backup-destinations/decentralized-providers/sia-destination.md). # Sia Destination This page describes the Sia storage destination {% hint style="danger" %} The Sia destination has been **removed**, as the implementation was not compatible with the hard-fork of the Sia network (canary 2.1.0.119, first stable release without it: 2.2.0.0). The `sia://` URL is no longer recognized. This page is kept for reference only. {% endhint %} Duplicati supports backups to the [Sia network](https://sia.tech) which is a large-scale decentralized storage network. To use the Sia destination, use this URL format: ``` sia://:/ ?sia-password= ``` If the host is supporting unauthenticated connections, you can omit the password. The default port is `9980` if none is supplied and the default path is `/backup` if none is supplied. ## Advanced options To adjust the amount of redundancy in the Sia network, use the option `--sia-redundancy`. Note that this value should be more than `1`. --- # 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.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.duplicati.com/backup-destinations/decentralized-providers/sia-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.
