# Manage Data Sources

As a data owner, you can [edit your data source settings](#edit-a-data-source) and [disable](#disable-a-data-source), [delete](#delete-a-data-source), and [re-enable](#enable-a-disabled-data-source) a data source.

For other guides related to data source members and management, see the [Related guides section](#related-guides).

## Bulk edit data sources

Data owners can bulk edit data sources.

1. Navigate to the **Data Sources** page.
2. Select the checkboxes for the data sources you want to edit. *Note that when editing a connection string using bulk edit, all data sources from that connection must be selected.*
3. Select the action you want or click **More Actions** for additional options.
4. Confirm your edits by following the prompts in the modals that appear.

## Resync policies

### Resync data policies

Users can manually resync data policies for all Immuta integrations.

1. Navigate to the **Data Sources** page.
2. Select the **checkboxes** for the data sources you want to sync data policies for.
3. Click **More Actions** and select **Sync Data Policies**.

### Resync grants and data policies

For Databricks Unity Catalog integrations, users can manually resync both subscription and data policies through the data source health check.

1. Navigate to the **data source** you would like to resync policies for.
2. Click the **health status** in the top corner.
3. Click **Sync All Policies**.

To sync grants and data policies using the API, see the [Subscribe to and manage data sources guide](/saas/developer-guides/api-intro/immuta-v1-api/data-sources.md#resync-data-policies-and-grants).

## Disable a data source

Disabling a data source hides it and its data from all users except the data owner. While in this state, the data source will display as disabled in the console for the data owner and other users will not be able to see it at all.

1. Navigate to the data source.
2. Click on the **more actions** icon and select **Disable**.

A label will appear next to the data source indicating it is now disabled, and a notification will be sent to all users of the data source informing them that the data source has been disabled.

{% hint style="info" %}
**Disabled data sources and Immuta policies**

Disabling a data source for one of the integrations below removes subscription and data policies from that data source; policies will not be applied until the data source is re-enabled:

* Azure Synapse Analytics
* Databricks Unity Catalog
* Google BigQuery
* Redshift
* Snowflake
  {% endhint %}

## Enable a disabled data source

1. Navigate to the data source.
2. Click on the **more actions** icon and select **Enable**.

A notification will be sent out to all users of the data source informing them that the data source has been enabled. After you enable a data source, existing policies on that data source will take effect.

## Delete a data source

Deleting a data source permanently removes it from Immuta. Data sources must first be disabled before they can be deleted.

1. [Disable the data source](#disable-a-data-source).
2. Navigate to the data source, click the **more actions** icon and select **Delete**.
3. Confirm that the data source should be deleted by clicking **Delete**.

A notification will be sent out to all users of the data source informing them that the data source has been deleted.
