+#!/usr/bin/env bb
+;; Usage: bb backup.clj
+;;
+;; 备份脚本功能:
+;; 1. 备份所有 Docker volumes 到 /home/eltrac/Backup
+;; 2. 备份 Akkoma 数据库到 akkoma_full_backup.sql
+;; 3. 使用 restic 备份 /home 和 /etc 到 contabo-backup 仓库
+;;
+;; 说明：
+;; 1. forgejo 等应用使用挂载到 Home 目录子目录的 SQLite 数据库，所以直接备份整个 /home 目录就好
+;; 2. 由于 docker volumes 已经单独备份，所以不必备份 /var
+;; 3. 目前暂时不能自动化，因为 restic 备份需要输入 repository 密码
