And what will you do when that company goes bankrupt and shuts down?  Your 
best case scenario is that you will get 90 days notice.  Have any of these 
business gone away with no notice at all yet?  I'd be wary of any company 
that says they can store unlimited data for less than the price of a 2 TB 
hard drive.  There are no economies of scale with respect to high-end 
storage, only the administration of that storage--when the amount of data 
stored gets very large, the cost of the staff members maintaining it become 
far less significant than the cost of the storage array + rent/air 
conditioning/electricity/redundancy location/etc of the facility housing it.

If you really need to keep the data you have to figure all the issues such 
as exactly how long you need it for and how rapidly you need to be able to 
get it, as well as how often.  If you don't care enough about long-term 
accessibility of the data to pay for 100% likelihood you'll be able to get 
it whenever you need it, you're probably just paying for something you'll 
never use.
