Unfortunately no one has answered Juan's question.
Any Data Domain, Reo, Septon, Falcon Stor users out there?

        Some VTL products' de-duplication technology is eons beyond 
compression, with low level pattern matching, etc, etc, enabling upt to 25:1 
effective "compression".
         
        VTL allows you to pool disk on a single VTL that can be shared to 
multiple media servers as virtual tape drives, whereas DSSU cannot be shared, 
so you must pre determine how many jobs per storage unit/media server you will 
run in a given night, and allocate the appropriate amount of disk per media 
server.
         
        if you have an operations group that is accustomed to tape, it 
maintains the tape paradigm they're familiar with.
         
        VTLs can be clustered, so you can have a second VTL at a second site, 
replicated over IP, without getting into duplication, vaulting, or any sort of 
DR copy within the backup app.
         
        other stuff, but I'm outta here for the day, and that's all that on the 
top of my mind at the moment.

                I guess this begs the question to the audience and the people 
that have put in VTL's ... what problems does a VTL solve that D2D can not?  
                 
                I think the list so far is:
                 
                1.  Administration is easier
                2.  Possibly performance
                3.  Compression (1/2 the disk of D2D)
                4.  I can use it to stress test a new NBU release
                 
                Anything else?
