If you use the loader commands DBEXTRACT or CATALOGEXTRACT ALL to unload data, then you can use an external backup tool.
Connecting External Backup Tools
The external backup tool for the loader session is determined using the loader command SET BACKUPTOOL.
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.
Enter TAPE as the media type (mediumtype_spec).
