If you use the loader commands DBLOAD or CATALOGLOAD ALL to load data, then you can use an external backup tool.
See Configuration of External Backup Tools for SAP DB.
Use the loader command SET BACKUPTOOL to specify the external backup tool for the loader session.
You start to load the data directly from the Loader.
Specify the external backup ID (TAPE <ebid_spec>) as the media type (mediumtype_spec).
