Cloud and Object
@dsfgdsd Control unless you've created the cloud yourself? Plus what do you do if the cloud company goes bust, etc etc. I still don't trust it fully but it has it's place for me, i.e. personal crash plan.
@joejones regarding object storage I know nothing of EMC's offering but with the two other vendors we tried (we're now using one) getting data in and out is pretty easy using standard HTTP GET and PUT commands. Admittedly you have to build your own system for keeping track of file to object ID. But I guess if you need to look at object storage then you'd probably have the skills in house anyway.
