Next, you should identify the required primary and recovery locations to ensure that the operating environments are compatible and the necessary resources are available. A primary location is the location that does an aggregate group backup of a specific application. A recovery location is the location where the aggregate group recovery of that specific application is performed.
Last, you should consider data set naming conventions to avoid duplicate data set names, and if system-managed data sets are to be recovered, you must ensure that the SMS constructs and attributes are compatible. Once the data sets needed to recover an application are identified, you can define the aggregate group.
