> When restoring a collection we can pass in the replicationFactor
> However while restoring the collection we don't make use of this param and
> end up using whatever is present as the nrtReplicas key in the state.json
>
> {code:java}
> int numNrtReplicas = getInt(message, NRT_REPLICAS,
> backupCollectionState.getNumNrtReplicas(), 0);
> if (numNrtReplicas == 0) {
> numNrtReplicas = getInt(message, REPLICATION_FACTOR,
> backupCollectionState.getReplicationFactor(), 0);
> }{code}
> The tests didn't catch this as the create collection call from SolrJ sets
> nrtReplicas = replicationFactor and then we never restore with a different
> replicationFactor
