 监测任务每五分钟执行，正常状态为`healthy`。默认只记录结构化状态和systemd日志；在`/etc/data-terminal-cloud/monitor.env`配置`ALERT_WEBHOOK_URL`后，状态变化会发送带时间戳和HMAC-SHA256签名的JSON通知。完整检查项、签名规则、阈值和失败分支见[《单机云端健康监测与告警手册》](../../docs/server-health-monitoring.md)。

+```bash
+chmod 0755 deploy/server/install-ossutil.sh \
+  deploy/server/install-offsite-backup.sh \
+  deploy/server/sync-backup-offsite.sh
+sudo deploy/server/install-offsite-backup.sh
+```
+
+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)。
