Hi, I'm using the SnapshotDeletionPolicy class to backup my index. I basically call the snapshot() method from the class SnapshotDeletionPolicy at some point, get a list of files that changed, copy then to the backup folder, and finish by calling the release() method.
The problem arises when, in between backups, I optimize the index by opening it with the IndexWriter class and calling the optimize() method. When I don't optimize in between backups, here is what happens: The first backup copies the segment composed by the files _0.cfs and segments_2. The second backup copies the files _1.cfs and segments_3, and the third backup copies the files _2.cfs e segments_4. I can open the backup folder with Luke without problems. When I do optimize in between backups, the copies are as follow: The first backup copies the segment composed by the files _0.cfs and segments_2. The second backup copies the files _1.cfs and segments_3, and the third backup copies the files _3.cfs e segments_5. In this case, when I try to open the backup folder, Luke gives a message saying that it can't find the file _2.cfs. My question is: how can I backup my index using the SnapshotDeletionPolicy and having to optimize the index in between backups? Am I using the right backup strategy? Thanks, Lucas
