Sorry for the english/german mix...

Perhaps I did not get my question to the point:
How can I simulate a "real streamer with tapes" _transparent_ for any
backup software (and any FBSD or Linux OS).
It would be nice no use the implemented database of the backup software
(like Yosemite/Tapeware or products like this), or other features,
whitout buying a streamer.

And, perhaps, this transparency would get so far that even tar or cpio
think they write onto a "real streamer" and not to a real file.

If theres no solution for all, is there any backup software able, to
work like this?

thanks in advanced
Christian
