A postCommit hook (configured in solrconfig.xml) is called in a safe place for every commit. You could have a program as a hook that normally did nothing unless you had previously signaled to make a copy of the index. > Then, I think, the only solution is to retrieve all documents from the > Solr server via an all-matching query and store the search result into > some files on hard disk.

That's a pretty expensive way to do it, but it would work assuming all the fields were stored. > If this operation would take several minutes: can other clients still > perform queries on the server or even do updates (which should be > delayed for consistency)? Other clients could continue to do queries, and updates would not need to be delayed (they won't be visible until a commit). -Yonik
