# Cron Job: 聊天记录每日备份

**Job ID:** 3ce78c2f616f
**Run Time:** 2026-05-18 02:01:14
**Schedule:** 0 2 * * *

## Prompt

[SYSTEM: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]

请完成以下聊天记录备份任务：

1. 创建备份目录（如果不存在）：/root/.hermes/backups/
2. 生成带时间戳的备份文件名，格式：sessions_backup_YYYYMMDD.tar.gz
3. 将 /root/.hermes/sessions/ 目录下所有 .jsonl 和 .json 文件打包压缩
4. 只保留最近 7 天的备份（删除更早的 .tar.gz 文件）
5. 备份完成后，输出备份文件路径和大小

备份命令参考：
  BACKUP_DIR="/root/.hermes/backups"
  DATE=$(date +%Y%m%d)
  BACKUP_FILE="${BACKUP_DIR}/sessions_backup_${DATE}.tar.gz"
  tar -czf "$BACKUP_FILE" -C /root/.hermes sessions/
  # 只保留最近7天
  find "$BACKUP_DIR" -name "sessions_backup_*.tar.gz" -mtime +7 -delete
  ls -lh "$BACKUP_FILE"

最终请简洁汇报：备份文件路径、大小、保留的备份数量。
