Actually, my question is why do it this way at all? Why not index directly to your "live" nodes? This is what SolrCloud is built for.
There's the new backup/restore functionality that's still a work in progress, see: https://issues.apache.org/jira/browse/SOLR-5750 You an use "implicit" routing to create shards say, for each week and age out the ones that are "too old" as well. Another option would be to use "collection aliasing" to keep an offline index up to date then switch over when necessary. I'd really like to know this isn't an XY problem though, what's the high-level problem you're trying to solve?
