I'm evaluating backup and offsite backup options for work right now. We
have about 1.5TB that we need to backup.

We're still in the planning phase, so I haven't seriously started
looking at our options yet, but somebody recommended to me earlier in
the week that some sort of JBOD array was the way to go. The Internet
Archive spun off a company called Capricorn Technologies that makes
something called "Petaboxes". They are 1/1.6/2 TB 1u rack nodes that you
can stack together for a petabyte of storage.

Here's their site:

I contacted them a few days ago and asked for pricing and info, but so
far no one's gotten back to me yet.

Oddly enough, the Petabox nodes don't use RAID internally for some
reason that escapes me at the moment. They just have some nodes set up
as mirrors.

I recommend rsnapshot if you are not using it already:
