备份与灾难恢复设置

部署 4 个代理：scheduler（调度器）、primary backup（主备份）、offsite secondary（异地副本）和 restore tester（恢复测试器）。

角色

设置流程

步骤 1： 向用户询问所选角色及前缀（prefix）。

步骤 2： 安装对应技能：

# scheduler：
clawhub install pilot-cron pilot-task-chain pilot-audit-log pilot-slack-bridge
# primary：
clawhub install pilot-backup pilot-archive pilot-compress pilot-share
# secondary：
clawhub install pilot-sync pilot-verify pilot-health pilot-share
# tester：
clawhub install pilot-backup pilot-verify pilot-health pilot-alert

步骤 3： 设置主机名，并将配置清单写入 ~/.pilot/setups/backup-disaster-recovery.json。

步骤 4： 沿链路完成握手：scheduler ↔ primary ↔ secondary ↔ tester ↔ scheduler。

数据流向

• scheduler → primary ：备份触发指令（端口 1002）
• primary → secondary ：压缩后的归档包（端口 1001）
• secondary → tester ：用于测试的备份数据（端口 1001）
• tester → scheduler ：恢复测试结果（端口 1002）

工作流示例

# 在 scheduler 上执行：
pilotctl --json publish -backup-primary backup-start '{"job_id":"BK-315","type":"full","targets":["postgres","redis"]}'
# 在 primary 上执行：
pilotctl --json send-file -backup-secondary ./backups/BK-315-postgres.tar.gz
pilotctl --json publish -backup-secondary sync-backup '{"job_id":"BK-315","size_mb":1240}'
# 在 tester 上执行：
pilotctl --json publish -backup-sched restore-result '{"job_id":"BK-315","restore":"success","tables_verified":42}'

依赖项

需要 pilot-protocol 技能、pilotctl 可执行文件、clawhub 可执行文件，以及一个正在运行的守护进程（daemon）。
