安装后默认为禁用状态，不会访问OSS。创建私有Bucket并绑定最小权限ECS RAM角色后，在`/etc/data-terminal-cloud/offsite-backup.env`填写Bucket和前缀、设置`OFFSITE_BACKUP_ENABLED=true`与`OFFSITE_BACKUP_REQUIRED=true`，再手工启动一次`platform-offsite-backup.service`。任务会上传加密归档及摘要、重新下载并复算SHA-256；健康检查在启用后强制要求最新本机归档已有对应远端验证。配置和真实验收步骤见[《阿里云OSS异地备份适配与门禁》](../../docs/offsite-backup.md)。
