Have you tried the replication API backup command here? https://cwiki.apache.org/confluence/display/solr/Index+Replication#IndexReplication-HTTPAPICommandsfortheReplicationHandler
Warning, I haven't worked with this personally in this situation so test. I do have to ask why you think SSDs are required here and if you've measured. With proper warming, most of the index is held in memory anyway and the source of the data (SSD or spinning) is not a huge issue. SSDs certainly are better/faster, but have you measured whether they are _enough_ faster to be worth the added complexity?
