生命周期策略是一种自动化规则，用于在不同存储层之间自动转换数据、设置保留策略和管理过期对象，无需手动操作。
Key Features
- 自动存储层转换：根据预设规则将数据从热存储移动到冷存储
- 保留策略：设置快照和对象的保留期限
- 过期清理：自动删除过期对象和不完整的分段上传
- 成本优化：减少存储费用，优化存储支出
AWS Services
- S3 Lifecycle Policies：转换对象到 S3 Standard → Intelligent-Tiering → Glacier 层级
- EFS Lifecycle Policies：将文件在标准层和不频繁访问层之间移动
- EBS Snapshot Lifecycle：归档快照到 Archive 层，使用 DLM 或 AWS Backup
