I presume you're referring to the index summary (i.e Summary.db files). These just contain a sampling of the (immutable) Index.db files, and are safe to hardlink in the way that you've described. The sampling level of the summary (which is what can change over time) is serialized at the start of the Summary.db file. If you're truly paranoid, you can skip the Summary.db files and they'll be rebuilt on startup. -- Tyler Hobbs DataStax <http://datastax.com/>
