## Definition
|
|
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
|
|
|
|
## Implementation
|
|
```json
|
|
{
|
|
"Rules": [
|
|
{
|
|
"ID": "MoveToGlacier",
|
|
"Status": "Enabled",
|
|
"Filter": {"Prefix": "archive/"},
|
|
"Transitions": [
|
|
{"Days": 365, "StorageClass": "GLACIER"}
|
|
],
|
|
"Expiration": {"Days": 1825}
|
|
}
|
|
]
|
|
}
|
|
```
