But actually much better would be to do the backup and restore on Solr level.
Solr doesn't currently have this capability. We do have functionality that can download index configs from ZK to the filesystem, but not all the cluster contents in ZK.
If the ZK is dedicated to Solr, I believe you can copy the entire "version-2" directory from the ZK datadir and install it in new ZK nodes while they are down, then start them up.
