Disaster recovery is not only about replicating your virtual machines but also about end to end application recovery that is tested multiple times, error free, and stress free when disaster strikes, which are the Azure Site Recovery promises. If you have never seen your application run in Microsoft Azure, chances are that when a real disaster happens, the virtual machines may just boot, but your business may remain down.
Why use Azure Site Recovery “recovery plans”? Recovery plans help you plan for a systematic recovery process by creating small independent units that you can manage. These units will typically represent an application in your environment. Recovery plan not only allows you to define the sequence in which the virtual machines start, but also helps you automate common tasks during recovery.
