This was mentioned before but seems not to have gotten any attention: can't you use the ReplicationHandler by just going to a URL like this?: http://host:8080/solr/replication?command=backup&location=/home/jboss/backup The 2nd edition Lucene in Action book describes a way to take hot backups without stopping your IndexWriter (pp. 374ff), and it appears that ReplicationHandler uses a similar strategy if I'm reading the code correctly (Solr 3.6.1; I guess v4 is the same). It'd be great if someone more knowledgeable could confirm that you can use the ReplicationHandler to take hot backups. I'm surprised to see such a long thread about starting/stopping index jobs when there is such an easy answer. Or am I mistaken and at risk of corrupt backups if I use it?
