I have a setup of ELK 7.10.0v. I am taking backup of elasticsearch index using snapshot API.
I have a doubt while taking backup with sanpshot which shards backup does it takes like primary or replica or it takes backup of both the shards?
It will store a single copy of the data so the size required on disk is basically the size of the primary shards. I assume primary shards are used for the snapshot but an not certain. This should not matter though.
