Additional info:

I don't want to have the behavior "only start writing to a tape if we
have more than X % of tapesize to write".

I simply want to serialize duping to holding disk and writing to tape.

The holding disk(s) (it will be a RAID1 array, RAID0 if needed) should
not be stressed by parallel dumping and taping ... I want to make sure
that writing to tape happens with full speed ... no stop and go for that
tape drive.

For now I don't care for optimal overall runtime, that server might even
write to tape while people are already at work in the morning (the
backup server is a completely separate box).

So it would be nice to have some simple boolean parameter for this. And
I assume it would be rather easy to implement for a programmer (which I
am not).

Thanks, Stefan
