from my experience what you say about DSSU is incorrect, a single DSSU cannot stage the data off to multiple tape tape pools - if you have a requirement to stage to different tape pools you need to have a at least one DSSU per tape pool,

Not here - In fact I stand by my previous response - in that you can
configure a LTO2 Drive to accept an LTO1 drive.
Must admit, not seen the problem you mention with regards to

NetBackup 5.n was licenced by tape drives. NetBackup 6.n is licenced by
TB in the VTL. I don't know the detail, e.g. is that raw TB etc. I also
