i use snapshot method backup elasticsearch nodes, works follow: put /_snapshot/my_backup/snapshot_1?wait_for_completion=true after new data added elasticsearch, it's not contained in snapshot, need run periodically, there data loss if goes wrong between 2 snapshots, there anyway handle it? there continuously backup method elasticsearch?
if want have "backup" of sort in-sync data in cluster, consider building 2 clusters. whatever indexing, updating, deleting operations "main" cluster has, need mirror operations on "backup" cluster well. there no other way.
