You may be thinking, “Microsoft has my Office 365 data protected.” It does, but in a limited way and mainly focuses on keeping the services available to recover from a hardware failure or for data durability issue. Microsoft is not responsible when you make a mistake like accidentally deleting an email or your whole outlook account – or when a malicious ransomware attack puts your entire business on hold. Having and Office 365 backup in such case can save the day and even your business.
