AWS S3 备份

基础操作

# 上传文件
aws s3 cp backup.tar.gz s3://my-bucket/backups/

# 上传目录
aws s3 sync /backup s3://my-bucket/backups/

# 存储类型
aws s3 cp backup.tar.gz s3://my-bucket/ --storage-class STANDARD_IA
aws s3 cp backup.tar.gz s3://my-bucket/ --storage-class GLACIER

# 服务端加密
aws s3 cp backup.tar.gz s3://my-bucket/ --sse AES256
aws s3 cp backup.tar.gz s3://my-bucket/ --sse aws:kms --sse-kms-key-id alias/my-key

# 应用策略
aws s3api put-bucket-lifecycle-configuration \
    --bucket my-bucket \
    --lifecycle-configuration file://lifecycle.json

跨区域复制

# 启用版本控制
aws s3api put-bucket-versioning \
    --bucket source-bucket \
    --versioning-configuration Status=Enabled

# 配置复制规则
aws s3api put-bucket-replication \
    --bucket source-bucket \
    --replication-configuration file://replication.json

阿里云 OSS 备份
