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.
