I use SolrCloud. Let's assume that I want to move all indexes from one place to another. There maybe two reasons for that:
First one is that: I will close all my system and I will use new machines with previous indexes (if it is a must they may have same network topology) at anywhere else after some time later. Second one is that: I know that SolrCloud handles failures but I will back up my indexes for a disaster event. How can I back up my indexes? I know that I can start up new nodes and I can close the old ones so I can move my indexes to other machines. However how can I do such kind of backup (should I just copy data folder of Solr nodes and put them to new Solr nodes after I change Zookeeper configuration)? What folks do?
