Chapter 10. Managing Geo-replication

This section introduces geo-replication, illustrates the various deployment scenarios, and explains how to configure geo-replication and mirroring.

10.1. About Geo-replication

Geo-replication provides a distributed, continuous, asynchronous, and incremental replication service from one site to another over Local Area Networks (LANs), Wide Area Networks (WANs), and the Internet.

Geo-replication uses a master–slave model, where replication and mirroring occurs between the following partners:

Master – the primary Red Hat Gluster Storage volume.
Slave – a secondary Red Hat Gluster Storage volume. A slave volume can be a volume on a remote host, such as remote-host::volname.
