As far as I’m aware the current stable release of HBase, 0.2, does not support replication, although it is being built into the next version.

How would you recommend replicating a standalone (non-distributed) deployment of HBase (0.2) ?

I want the secondary instance to be used as a working backup i.e. read-only. I can afford asynchronous backups with “eventual consistency”, and a small amount of loss (the data is non-critical).

So far my only thought was to manually update the secondary instance, asynchronously, after writing to the primary instance.

    HBase natively tolerates node failure/failover (assuming that you are running on HDFS), so it’s not really necessary to maintain a replica like you would with a RDBMS.

    What’s wrong with just using HDFS replication?

    EDIT: In this case, you would switch from standalone to distributed, and just have 2 nodes with a replication factor of 2.
