Thanks Ed but I'm confused. If I say that Netbackup can send 15 streams to a
DSSU and then I have 15 clients sending streams all at once to that DSSU,

elaborate a bit on how that works?
Thanks,

Hello List,
Just wanted to get some opinions about whether disk staging units are
worthwhile. My backup server has two BasicDisk staging units with the
storage units configured such that the data goes to disk and is then
moved to tape. I have a tape library with four LTO-3 drives connected
via FC.
