> Since 2.2, the installed version is compared with the version persisted in system.local (if any) at startup. If these versions differ, the system keyspace is snapshotted before proceeding in order to enable a rollback if any other issue prevents startup from completing. Although the method to perform this check & snapshot is still present in {{SystemKeyspace}}, its only callsite was mistakenly removed from {{CassandraDaemon}} in CASSANDRA-12716.
