How to take incremental backup in lucine?

Question

I want to perform a backup and restore process in my project. I used snapshotdeletionpolicy to make a hot backup of my indexes to another place.

Is it possible to take an incremental backup in lucene? (For example, if I added 100 documents to lucene, than I should update these indexes during backup in my backup location)

If so, how do I achieve this? Will snapshotdeletionpolicy help me do this?

Using ReplicationHandler, we can update the index using 10 seconds in the main copy and get a backup after checking this URL
