On a similar note, I created a 1-drive STU for destaging because the DSSU has an annoying (and stupid) habit of allocating all available drives when it tries to destage. Of course this makes all the streams (3 in this case) go slowly because they're all reading from the same DSSU spindles. The 1-drive STU doesn't work. I can't help noticing that the option says "Maximum concurrent drives used for backup" (not duplication). This must be a bug since it defeats the whole purpose of the DSSU, which is to keep the tape drive spinning. 5.1 MP5 Linux (haven't tried it on MP4 yet).

Just to see if this is hurting you (I have done this at my 18 different NB sites), create a new storage unit in your library called "duplication". Make it 1 drive, on demand only. (you don't have to lessen the number of concurrent drives in you other storage unit). Try a duplication (manual or vault) and pick "duplication" as the destination storage unit. See if things speed up.
