No.

I've looked at what to use for backup and have found that a mobile hard
drive (2.5") in a ruggedized enclosure (especially the addonics Jupiter
ExDrive) provides better physical security at higher data density at
lower cost than a tape drive.

I'm using the 2.5" drive because the storage media has to fit in the
bank's safety deposit box with max width of 5".

Good luck with the DDS2.

Doug.
