We here at Associated Bureaus Inc. use HP's C1553A DDS-2
Autoloader. This unit will hold six 120 meter tapes, and with our
RoadRunner software, compression of 4:1 can be achieved. We
have two of these units, so we use them in parallel. We could
actually backup up to 192 GB unattended, however we only have
50 GB of disc. My tests indicate that it takes about three hours
to backup 40 GB's of data using this technology. I know I was
quite impressed.
