Thanks for the comments so far. As I noted (or tried to) this is
a second hand request and is specifically *not* backup - it's

We're talking about people who want to put a bunch of data
on a tape that may or may not be needed in 5 years time.
Perhaps 10. The "archival" bit is relevant; it's not a "backup".

I did not explain that this is a "remote" system wherein
Joe User has a (bunch of) data that falls into this category
that he wants to write to tape. In fact, there are multiple Joes
at multiple points around the planet.

There isn't a remote operator to phone up and ask to diddle with
the tape library - Joe wants to "do something" that results in
the data he points at being written to a tape (actually probably two),
those tapes then being removed at some point by someone on site and
filed appropriately. This sort of operation was not a problem when
Dinosaurs roamed the earth and some of us were running mainframe
operating systems that managed tape libraries that would track
ownership of tapes.

It's possible that in the future a BluRay drive would be an
alternative, but that's still only what, maybe 50GB? Tapes
can hold a lot more, and we are talking about several hundred
GB or more. Yes, you could write it to a couple of 1TB disks,
but (as mentioned elsewhere), I don't want to spin it for five
or 10 years; there are handy "removable disk units" which sound
good, but I haven't seen one with an autoloader, so it's manual
intervention every time it's needed.

Pulling it back over "the wire" is sort of an option, but with
large amounts of data it can take a long time (unless you have
lot of bandwidth :)

As the old saying goes, 'never understimate the bandwidth of
a station wagon full of tapes...'
