DownloadGluster 3.2: Managing GlusterFS Geo-replication
From GlusterDocumentation
GlusterFS Geo-replication provides a continuous, asynchronous, and incremental replication service from one site to another over Local Area Networks (LANs), Wide Area Network (WANs), and across the Internet.
Using GlusterFS Geo-replication, you can establish data redundancy in your storage environment, providing disaster recovery through existing LAN, WAN, and Internet connections.
GlusterFS Geo-replication uses a master–slave model, whereby replication and mirroring occurs between the following partners:
- Master – A GlusterFS volume
- Slave – A slave can be of the following types:
- A local directory which can be represented as file URL like file:///path/to/dir. You can use shortened form, for example: /path/to/dir.
- A GlusterFS Volume - Slave Volume can be either a local volume like gluster://localhost:volname (shortened form - :volname) or a volume served by different host like gluster://host:volname (shortened form - host:volname).
Note: Both of the above types can be accessed remotely using SSH tunnel. To use SSH, add an SSH prefix to either a file URL or gluster type URL. For example: ssh://root@remote-host:/path/to/dir (shortened form - root@remote-host:/path/to/dir) or ssh://root@remote-host:gluster://localhost:volname (shortened from - root@remote-host::volname). This section introduces GlusterFS Geo-replication, illustrates the various deployment scenarios, and explains how to configure the system to provide replication and mirroring in your environment.
