  name: ElastiCache Automatic Backups - Disabled
  author: DhiyaneshDK
  severity: medium
  description: |
    Ensure that Amazon ElastiCache is configured to take automatic daily backups for Redis cache clusters.
  impact: |
    Disabling ElastiCache automatic backups increases the risk of data loss, as you won't have point-in-time recovery options in case of data corruption or accidental deletion.
  remediation: |
    enable automatic backups in the AWS Management Console for your ElastiCache Redis or Memcached cluster to ensure regular snapshots for data recovery.
