And where is the settling for multi streaming?

just the opposite.
multiplexing is the practice of writing multiple backup jobs simultaneously
to one tape/drive, interleaving segments of each backup on the tape.

Multiplexing is beneficial when you have new technology tape drives that
write 40+ MB/s natively, and clients that just can't push that much data
out. In most cases with new tape drive technology the problem is that
tapedrives are TOO fast, rather than not being fast enough.

If you want to pull multiple streams of data from one client and "stripe" it
across multiple drives, that is known as multi-STREAMING.

Can someone explain what this does? How can I backup data and have it
stripped across more drives to speed a back up faster? We are having a
"discussion" about this and how multiplexing works versus data streaming.
