 - [BlobClient.start_copy_from_url](/python/api/azure-storage-blob/azure.storage.blob.blobclient#azure-storage-blob-blobclient-start-copy-from-url)
 
-This method returns a dictionary containing *copy_status* and *copy_id*, which can be used to check the status of the copy operation:
-- *copy_status* will be 'success' if the copy completed synchronously or 'pending' if the copy has been started asynchronously
-- For asynchronous copies, the status can be checked by polling the `get_blob_properties` method and checking *copy_status*
-- Set *requires_sync* to True to force the copy to be synchronous

-The source must be a block blob no larger than 256 MB. The source URL must include a SAS token that provides permissions to read the source blob. To learn more about the underlying operation, see [REST API operations](#rest-api-operations).

 The following code example gets a `BlobClient` object representing an existing blob and copies it to a new blob in a different container. This example also gets a lease on the source blob before copying so that no other client can modify the blob until the copy is complete and the lease is broken.
