Making periodic snapshots by shutting down your cluster and 
doing a copy in HDFS is effective enough. You may want to
look at this also:
  https://issues.apache.org/jira/browse/HBASE-897


There's no live backup or snapshot capability in HBase now. 
You may want to monitor these issues:
  https://issues.apache.org/jira/browse/HBASE-7
  https://issues.apache.org/jira/browse/HBASE-50
One of these could produce results that support hot backup
at the file level.
