Elastic search - ccr plugin - recovering to point in time

Elastic Search

We are trying to set up a cross region resiliency for our es. We are exploring CCR plugin parallely.

We have a requirement that we need to recover our es cluster in our passive region from a point in time timestamp. The timestamp is an allignment between multiple components in our system. I was wondering what would be the way to achieve way to achieve this nuanced requirement in es. Any guidance on how we can meet this would be highly helpful

Cross-Cluster Replication (CCR) in Elasticsearch is fundamentally an active streaming replication mechanism designed for low-latency sync rather than point-in-time rollback.

If your resilience requirements mandate recovering the follower cluster to an aligned system-wide timestamp:

  1. CCR + SLM (Snapshot Lifecycle Management) Pattern: CCR alone cannot rewind translog operations. The standard architecture is to let CCR replicate continuously, while running hourly/daily SLM snapshots on either the leader or follower. For point-in-time recovery, you pause/unfollow the CCR index:
POST /<follower_index>/_ccr/pause_follow
POST /<follower_index>/_ccr/unfollow

And then restore the specific snapshot to that timestamp.
2. Point in Time (PIT) + Reindex: If the target timestamp is within your active translog retention window, you can use Elasticsearch's Point in Time API (POST /<index>/_pit?keep_alive=1h) combined with a date-range query in _reindex to materialize a static index at that precise timestamp.
