We have similar setups, and a combination of Flashbackup and DSSU has been our
best result. You will get much better performance to disk than tape, then run
it to LTO without affecting your client. I would also suggest you split your
server into separate policies for each drive letter, then restrict how many
jobs can go to the DSSU at a time (in other words- a dedicated DSSU for this
thing). That will allow you to get by with a smaller disk footprint, and also
spread the backup overhead out. Your fulls won't all be on the same day, but
for the type of data you describe that probably won't be an issue. The DSSU
will also take care of your multiplexing issue.
