LTO4 is rated at 120MB/s, so I'm guessing you factored in some compression
to get that up to 350MB/s. Regardless, using the 350MB/s as a starting
point, I think it works out to 1 tape drive being able to move 11PB/yr
(just using "PB/yr" makes me cringe). I actually came up with 4.5 tape

Ooooh, what an INTERESTING problem to have!
I'm not aware of any VTL that even approaches being able to handle this

It's a pretty daunting problem. If you take LTO4 (at 800 GB per cart),
assume with compression and some un-reclaimed space you'll average about 1

Hi Bob
Considering the amount of data, I would presume that it's not only a few files
being backed up, but a huge amount since most systems out there cant hold a few
files for a total of 50PB of data.
You will also have to consider what impact storing 50PB of data will have on
the TSM database
