Isn't the data hosting company job to do backups and redundancy? Unless they clearly state that they don't do that.

Redundancy - by definition - cannot be supplied by a single company.

Yes, your vendor may have their own redundant systems in place so that their internal problems don't become your problems. And that's nice. They should. But you always have a Plan B. And you always keep a local copy.

I'd say the opposite: Unless they clearly state they _do_ backups, they are not (legally) responsible for doing so.

That's what data hosting is. If they were doing webhosting, sure, but the article repeatedly states they were doing "data hosting".

Here's the company's web page detailing their data backup plan: http://www.cyberlynk.net/services_corporate/dsp_backup.cfm

What I'm saying is that whatever is in the contract is what matters. Data hosting, web hosting, data storage, whatever terms are used matter little.

EDIT: Case in point: We probably all agree that dropbox could be called "data storage", but they specifically say that backups and backup costs are to be done by the client (http://www.dropbox.com/dmca#terms), not by them.
