The simplest way is to stop all index writing (close the IndexWriter),
do the copy, then start your IndexWriter again.
If that's a problem (usually it is!) then use SnapshotDeletionPolicy
to protect the commit point (ie prevent any of the files it uses from
being deleted) while you are making the copy... this way you can take
a hot backup without pausing index writing...

When i started my application in another system, I could see my search database whiped out. Only write lock remains. The behaviour is unpredictable.
