冷备归档改用 OSS Multipart 顺序分片上传并加入可重试请求。 Complete 后通过签名 HEAD 严格核对远端对象长度，再更新清单或清理本地归档。 补齐签名查询、分片重试、缺失 ETag、Complete 歧义和 Abort 回归测试。 记录数据库冷备上传与清理边界的长期运维决策。

|

node -- scripts/database-backup-to-oss.mjs [--stop-service spacetimedb.service] [--restart-service-after genarrative-api.service] [--defer-upload]
|
||
node -- scripts/database-backup-to-oss.mjs --upload-archive <path>
|
||
|
||
说明:
|
||
将 SpacetimeDB 数据目录打包成 .tar.gz，并上传到阿里云 OSS 指定 bucket。
|
||
--defer-upload 只生成本地冷备份和 manifest，不上传；后续用 --upload-archive 异步上传。
|
||
默认读取 .env / .env.local / .env.secrets.local；生产服务可传 --env-file /etc/genarrative/api-server.env。
|
||
shell 环境变量优先级最高，不会被 env 文件覆盖。
|
||
|
||
常用环境变量:
|
||
GENARRATIVE_DATABASE_BACKUP_DATA_DIR 数据目录；生产建议 /stdb
|
||
GENARRATIVE_DATABASE_BACKUP_WORK_DIR 本地临时备份目录；生产建议 /var/lib/genarrative/database-backups
|
||
GENARRATIVE_DATABASE_BACKUP_OSS_BUCKET 备份 bucket；未设置时回退 ALIYUN_OSS_BUCKET
|
||
GENARRATIVE_DATABASE_BACKUP_OSS_PREFIX 对象前缀，默认 database-backups
|
||
GENARRATIVE_DATABASE_BACKUP_OSS_ENDPOINT OSS endpoint；未设置时回退 ALIYUN_OSS_ENDPOINT
|
||
GENARRATIVE_DATABASE_BACKUP_KEEP_LOCAL true 时保留本地 tar.gz
|
||
GENARRATIVE_DATABASE_BACKUP_MIN_FREE_BYTES 备份前要求 work dir 所在文件系统至少有这些可用字节；未设置时按数据目录大小估算
|
||
ALIYUN_OSS_ACCESS_KEY_ID / ALIYUN_OSS_ACCESS_KEY_SECRET
