Hello, We are trying to replicate the data on one ElasticSearch cluster onto another using rsync and so far, to no avail. We'd like to perform some recovery experiments using v.0.90.0.RC1 but we need to assume the data and setup of one environment (Cluster A) to our testing environment (Cluster B). We have the following questions: 1. Is there a specific place the cluster identity is coded within ElasticSearch, if anywhere? 2. Is it possible to make Cluster A assume the data of Cluster B, clobbering Cluster B's original contents? 3. Is it possible to replicate an index from Cluster A to Cluster B and force it to assume the shards, etc? This is purely for developmental purposes, so it doesn't matter if we need to restart ElasitcSearch or if we need to manually modify any files. We are using a local gateway.

This should be easy - just rsync over the data/ directory. The only thing that you may need to change is the cluster name, which forms part of the path under data/ Clint On Thu, May 2, 2013 at 8:25 PM, [rachel@infochimps.com](mailto:rachel@infochimps.com) wrote: > Hello, > > We are trying to replicate the data on one Elasticsearch cluster onto > another using rsync and so far, to no avail.
