# ModifyDBClusterSnapshotAttribute
<a name="API_ModifyDBClusterSnapshotAttribute"></a>

Adds an attribute and values to, or removes an attribute and values from, a manual cluster snapshot.

To share a manual cluster snapshot with other Amazon Web Services accounts, specify `restore` as the `AttributeName`, and use the `ValuesToAdd` parameter to add a list of IDs of the Amazon Web Services accounts that are authorized to restore the manual cluster snapshot. Use the value `all` to make the manual cluster snapshot public, which means that it can be copied or restored by all Amazon Web Services accounts. Do not add the `all` value for any manual cluster snapshots that contain private information that you don't want available to all Amazon Web Services accounts. If a manual cluster snapshot is encrypted, it can be shared, but only by specifying a list of authorized Amazon Web Services account IDs for the `ValuesToAdd` parameter. You can't use `all` as a value for that parameter in this case.
