title: Hbase replication
body: <p>My Hbase running on three machines,one for hmaster and the other two as regionServers,Now I'm thinking I have to do some replication work since this is a production enviroment for preventing machine crashing or power off.But I read some Hbase documents and couldn't find any way to replicate my data. The only way I'm using is set hadoop replication,I set hdfs-site.xml dfs.replicate=1.
  So is there any better ways to do the replication of Hbase for hot backup.
  Thanks in advance</p>
