Solr indexes are file-based, so there's no need to "dump" the index to a file.
In terms of how to create backups and move those backups to other servers, check out this page http://wiki.apache.org/solr/CollectionDistribution. Hope that helps. -----Original Message----- From: Jörg Kiegeland [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 02, 2008 3:17 AM To: solr-user@lucene.apache.org Subject: Backup of a Solr index Is there a standard way to dump the Solr index to a file or to a directory as backup, and to import a such saved index to another Solr index later? Another question I have, is whether one is allowed to copy the /data/index folder while the Solr server is still running, as easy alternative to do a backup (may this conflict with Solr holding open files?)? Happy new year, Jörg
