hi There,
I have 1 TB index , and I am trying to take a backup using snapshot. And I want to take regular backups/snapshots of the same.
So, will the elasticsearch supports the differential(delta from last backup) backup/snapshot? If yes how?

All snapshots in a repository are deltas of the original.

Even though it is getting a bit old, I think [this blog post](https://www.elastic.co/blog/found-elasticsearch-snapshot-and-restore) describes snapshot/restore quite well.
