Tony,
We just started using a DLT about a month ago.  We love it.  We bought the drive from Orbit Software and use the Backup+ product.  A full backup on our DDS-1 drives took nearly 6 hours.  Now, using the DLT, it takes about 55 minutes (about 11 GB of disk data).  We were able to do a reload a month ago in 1 hour and 47 minutes (about 10 GB of data).
Just be aware that tapes are expensive.  Depending on the type (Type III or Type IV), they can range from $40 to $90 per tape (I think....I for got the numbers).
Good luck
Tim

I am trying to justify the need of a DLT to management. Can
anyone give me any figures on the number of sites that currently use
DLT?

Also of the sites that have DLT's how many of them don't have
DDS's?  (I wouldn't think very many)

Is this something I am going to need to get to read our customers data?

Thanx in advance.
