I withdraw this question - it is covered in the Solr 5 reference manual. The suggestion is to use the replication handler, which suggests that this scheme still works. That's how I will go.

How do people manage backup in SolrCloud? I'm primarily interested in smaller indexes where backup is at all feasible. I imagine a system such as Facebook really has to hope it stays up and maybe do something similar to log shipping, e.g. keep intermediate results that were fed into Solr. My applications are likely to be a bit smaller, and classic system backups apply.
