Hi, I’m looking at setting up a snapshot window on my Elasticache instance. It’s currently setup as a aws_elasticache_replication_group with number_cache_clusters set to 2 and I’m not sure how I’m supposed to set the equivalent of the Backup Node Id in the Elasticache console (I want to backup only from the replica node, not the primary). I tried adding an aws_elasticache_cluster config for the node I want to back up from, but adding the snapshot_window there gives me the "replication_group_id": conflicts with snapshot_window error.
It doesn’t look like there’s any other way to configure which node gets snapshotted through Terraform?
