This is likely happening because you're attempting to copy a file that IndexWriter is currently writing?
You shouldn't do that (copy files that are still being written) -- that just wastes bytes (they aren't used by the index), and causes this failure on Windows. Instead, you should use SnapshotDeletionPolicy -- it tells you specifically which files make up the latest commit point. Those files will not be opened for writing (only for reading, if you have an IndexReader open on that commit) and they should copy just fine on windows. The "Hot backups with Lucene" article (NOTE: I'm the author) in upcoming Lucene in Action 2 revision shows how to do this -- it's available for download from http://manning.com/hatcher3.
