# SharePoint v2 (Graph API)
This page describes the SharePoint v2 storage destination
{% hint style="info" %}
As of Duplicati 2.3.1.0 the "SharePoint v2" backend has been renamed to just "SharePoint". The previous legacy "SharePoint" backend is now [deprecated](/backup-destinations/provider-specific-destinations/sharepoint-destination.md).
{% endhint %}
Duplicati supports using [Microsoft SharePoint](https://www.microsoft.com/en-us/microsoft-365/sharepoint/collaboration) as a storage destination. This page describes the SharePoint that uses the Graph API, for the [SharePoint provider that uses the legacy API, see SharePoint](/backup-destinations/provider-specific-destinations/sharepoint-destination.md).
## User interface
To configure the SharePoint v2 destination you need to pick a unique folder name for the backups, provide the site id, and then authorize Duplicati to work on your behalf. Simply click the "AuthID" link in the text field and the authentication process will start and fill out the "AuthID" when you are done.
## URL format for Commandline
To use SharePoint, use the following URL format:
```
sharepoint:///
?authid=
&site-id=
```
To use SharePoint v2 you must first obtain an `AuthID` by using a Duplicati service to log in to Microsoft and approve the access. See the [page on the OAuth Server](/duplicati-programs/oauth-server.md) for different ways to obtain an AuthID.
## Performance tuning options
If you need to gain more performance you can fine-tune the performance of chunked transfers with the options:
* `--fragment-size`
* `--fragment-retry-count`
* `--fragment-retry-delay`
For most uses, it is recommended that these are kept at their default settings and only changed after confirming that there is a gain to be made by changing them.

## 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/sharepoint-v2-graph-api.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.
