# How to restore a broken dataset



## Case description {#case-description}

You need to restore a broken dataset.

## Solution {#case-resolution}

{% note info %}

A possible reason for the dataset damage is that the dataset file has been deleted from the file connection.

{% endnote %}

You cannot recover any deleted objects in DataLens on your own. To do this, [create a support ticket](https://center.yandex.cloud/support). Provide the following information in your ticket:

1. Descriptions and list of damaged objects, e.g., connections, files, datasets.
1. Approximate date and time when the objects were deleted.
1. Why exactly you need to recover the deleted objects.

{% note alert %}

Our support does not guarantee the recovery of data deleted from DataLens buckets by users.
