CREDIT UNION GOES TO MANAGED CLOUD FOR TIGHTER SECURITY AND ZERO DATA FOOTPRINT
I like to look at an IT disaster recovery model like the OSI model for networking. At the bottom of the model layers 1-3 would be traditional backups. The middle layers 4-5 would be storage array replication. This method works well but it normally comes with added steps of storage presentation, drive scanning, VM imports, etc… on the recovery side. At the top, layers 6-7 would be application level replication where server images would be replicated in near real time. Active servers would be running at the IT disaster recovery site for database replication. When you look at IT disaster recovery in this way, the closer you are to the top the better outcome you will have in a true disaster scenario.
