If you use the loader commands DBEXTRACT or CATALOGEXTRACT ALL to unload 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 unload the data directly from the Loader. The Loader creates the pipes for unloading the backup data implicitly as part of the unload. These pipes must not exist before the unload.
Specify TAPE as the media type (mediumtype_spec).
