Agreed, if you have a terabyte or more then disk is the only way to
go, at least until some alternative medium arrives on the scene.
Tape may or may not be it, I'm thinking maybe the tape companies
might switch to a cheaper/faster HDD-based cartridge solution a la
the "Bernoulli" thing from the 1980s. The challenge is to get the
price-per-gig of archive down to something reasonable: if you want
to keep a long history of dumps, it's prohibitive to keep a file
drawer full of hard drives.
I'm posting here, though, to query why the heck a company needs to
store a terabyte or more of *anything*. My home system has a tenth
of a terabyte, mostly music files. Companies don't need to back up
music (unless they're in that business) and generally don't need to
back up video. Customer lists, financial data, source code and
that sort of thing simply don't require that much space.
Think about a financial services company that issues credit cards, and
they need to store data on every single transaction for years. They
*absolutely* need that backup. Think about however many billions of
transactions we're talking about every month.
You'd be surprised (or maybe not, if you reflect on it) just how many
companies need to store transaction data, or want to mine all of that.
And that's only one kind of data.
