+This integration allows you to use [Microsoft OneDrive](https://www.microsoft.com/en-us/microsoft-365/onedrive/online-cloud-storage) for [Home Assistant Backups](/common-tasks/general/#backups).
 
 Backups will be created in a folder called `Home Assistant\backups_<id>` in the `App Folder` of your OneDrive.
 `id` is part of your Home Assistant instance's unique id to allow backups from multiple instances to the same OneDrive account.
 The integration only has access to an application specific `Home Assistant` folder in the `App Folder` and cannot access any other parts of your OneDrive.

+## Backup folder is called `Graph`
+
+This integration uses Microsoft's Graph API to communicate with your OneDrive. Because of an [issue](https://github.com/OneDrive/onedrive-api-docs/issues/1866) in that API, the application folder is often not named with the name of the application (`Home Assistant`), but `Graph` instead. 
+
+There is no risk of different applications mixing in that `Graph` folder, if you already have such a `Graph` folder from a different application, the next folders will just be called `Graph 1`, `Graph 2` and so on. 
+
+You should be able to manually rename the folder to something else, without the integration breaking.
