Does elastic search have the option to do diffrential backup and restore. The only option I see in the document given is to take the whole snapshot of the index.

CodePudding user response：

there's no way to take an incremental one, no

snapshots themselves are incremental. that means that if you take a snapshot at $day0, then every day after that, each of the subsequent snapshots will be whatever has changed from $today and $today-1
