Hi,

I'm not using multiplexing. I just want to use multistream for 1
backup job. Basically just 1 backup image. This backup uses 2 tapes,
one after another. I want to speed my backup, hence I want to try
multi-stream. At the moment bpduplicate uses 1 tape after another on 2
drives. I wonder if multi-stream uses the same format here. Anyone
ever experience this?

Thanks.
