I added cost/GB numbers to the end of this nice chart, hope my math is ok.
It looks like the media cost of VXA is about in the middle -- not
great, not a bargain.
DDS-3, which happens to be the format I am comparing to VXA, is tied
to be the second cheapest - the only format cheaper is the only one
on the list I never heard of...
And remember, the cost/GB is basically a "best case" figure, if you
don't always use the full capacity of a tape. Large capacity is very
convenient, but smaller capacity is often a much better deal.
For many scenarios the media price is insignificant, there are a ton
of different considerations when picking out a backup system. But if
anyone is cost conscious, and will be using a lot of media, they
should really do some calculations before picking a system.
