The backup directory should just be a clone of the index files. I'm
curious to know whether it is a cp -r or a cp -lr that the replication

You would prevent commits by telling your app not to commit. That is,
Solr only commits when it is *told* to.
Unless you use autocommit, in which case I guess you could monitor your
logs for the last commit, and do your backup a 10 seconds after that.
Hmm. Strange - the files created by the backup API don't seem to
correlate exactly with the files stored under the solr data directory:

Am I correct in thinking that to restore from this backup, I would need
to do the following?
1. Stop Tomcat (or maybe just solr)
2. Remove all files under /var/lib/solr/data/index/
3. Move/copy files from /tmp/snapshot.20121220155853703/ to
/var/lib/solr/data/index/
4. Restart Tomcat (or just solr)
Thanks everyone who's pitched in on this! Once I've got this working,
I'll document it.
