Users may create data storage volumes that may each be stored by a data storage service. In an embodiment, chunks that differ between related volumes may be encrypted with different encryption keys. One or more of the encryption keys may be deleted in response to a request to delete a volume or a data chunk, rendering the volume and/or the data chunk unusable.
