Why would you, as a business, entrust your potentially business-critical IP:
* To a Service Provider you can't monitor or have independent verification of your data security? Can you hire a 3rd Party to investigate their internal procedures & verify that they're doing what they claim, that your data is as disaster-resistant as they claim, that you can actually get to your data as desired? Would you willingly equip your car with locks from a "Security Specialist" who refused to let you verify their locks worked?
* To a SP that, if you feel your business is better taken elsewhere, can hold your data hostage? Unless you keep a local copy of your data that you can access withOUT their Service (in which case you don't NEED their Service), they hold all the cards & you're now at the mercy of an Entity that has only ONE concern - their bottom line. Your data means *nothing* to them, and if you try to switch, they can dump it into the trash faster than you can request it back. Would you be willing to rent a car that, if you decided you didn't like & wished to rent a different one, were told that everything you had IN the car was now being held hostage until you paid the owner what-ever amount they felt like charging you for the items' return?
* To a SP that has been, can be, and will probably ALWAYS be, the most INsecure system on the internet? They are constantly having to patch all the bugs, security holes, and out-right coding-idiocy that consistently puts their own systems at risk, in the hopes that it will minimize the amount of "collateral damage" their customers suffer. Would you honestly be willing to entrust your family to be passengers in a vehicle from a manufacturer that was consistently having to recall their products to fix "safety issues"?
Think about it.
You're placing potentially business-critical information in the hands of a third party whom you can't audit, can't bargain with if you decide to change Service Providers, and can't EVER be sure that your data won't be stolen/sold to the first person/business who wants to take a shot at stealing/buying it.
It costs FAR less to host your own on-&-off-site data retention Servers, Disaster Recovery policies, & a Volume License Copy of MS Office.
The ROI for Covering Your Own Arse is much, MUCH less than the TCO for entrusting your business' future to the inept hands of Microsoft.
