I'm CTO of a TINY company, with pretty much exactly half this data. I run all storage and offside backups personally, because I can't afford a full time sysadmin yet.

And the cost of everything is PAIN to us.

If our building burned down we would lose data, but only the data we are Ok with losing in a fire.

I'd love to know the real reason. It's not some useless tech... it's politics, surely.
