Hi, AFAIK SolrCloud still doesn't support replication, that's why in the example you have to copy the directory manually. Replication has to be implemented by using the SolrReplication as you mentioned or use some kind of distributed indexing (you'll have to do it yourself). SolrReplication stuff is there to replicate the index and CAN replicate configuration files, this doesn't mean that you HAVE to replicate config files. Do you need to replicate configuration files too or just the index?
