ElastiCache Redis cluster should retain at least one automatic snapshot

What it checks

ElastiCache Redis cluster should retain at least one automatic snapshot

Where it applies

Terraform: aws_elasticache_cluster

CloudFormation: AWS::ElastiCache::CacheCluster

How to fix it

1. Set snapshot_retention_limit to at least 1 (7 recommended) and a snapshot_window outside peak hours. If this Redis is a pure disposable cache with a fast, authoritative rebuild path, this finding can be baselined with that justification.
