Acronis True Image Server 8, DLT-Streamertapedrive, ti_cons.exe - howto?

Hi,

i have Acronis True Image Server, Version 8, under windows XP,
and i have a DLT-8000-Tapedrive, connected via SCSI, which works fine with the Acronis-GUI.

But i want to use the streamer with the command line version, ti_cons.exe.
All i can see is that it is possible to specify a filename for the backup target with e.g. "/filename:backup.tib"

Which parameter do i need for ti_cons.exe to backup to the tapedrive?

Thanks a lot in advance, best regards :-)
