# Data Center Replication

GridGain data center replication lets you replicate data caches between multiple data centers and recover quickly when a data center goes offline.

GridGain enables you to replicate data caches between multiple data centers and quickly recover when a data center goes offline.

Data replication affects only caches. It does not copy cluster configurations, so you need to configure replica clusters manually. This method allows for various combinations of replica cluster configurations. For example, one cluster can replicate updates to multiple clusters, and multiple clusters can replicate data to each other.

The following topics provide information about configuring and managing data center replication:
