Why do I need multiple off-site locations.  Yes, I can see that a major
business might want to have their data stored in several locations, but
as ever there's a trade-off between security and cost.  If both my
office and my home had been nuked at the same time I think I'd have had
better things to worry about than yesterday's invoices.

Assess whether you *need* multiple off-site locations.  It's not a
given.  It might be that you do keep stuff at two separate off-site
locations, but not updated so often.  One is updated every 24 hours and
one every month.
