Multitier System Replication
To offer higher levels of availability you can link together multiple systems in a multitier system replication landscape.
After setting up a basic system replication scenario you add a third system to provide
another level of redundancy.
In a multitier setup the primary system is always on tier 1, a tier 2 secondary has a primary system as its replication source and a tier 3 secondary has the tier 2 secondary as its replication source.
