Mjolnir Shadow (雷神之影) 🌑

Automated rotating backup for OpenClaw workspaces with GPG-encrypted credential storage.

自动轮转备份系统，支持 GPG 加密凭证。

Requirements / 依赖

  • bash + curl — most Linux/macOS systems
  • Python 3.6+ — for setup wizard
  • GPG (gnupg) — for credential encryption (recommended)
  • WebDAV server — Nextcloud, ownCloud, Synology, etc.
  • Env var (optional): MJOLNIR_SHADOW_PASS — GPG passphrase for non-interactive cron runs

Quick Start / 快速开始

# 1. Interactive setup (creates encrypted config)
# 1. 交互式配置（创建加密配置）
python3 scripts/setup_backup.py

# 2. Run backup
# 2. 运行备份
bash scripts/backup.sh

# 3. Check status
# 3. 检查状态
cat memory/backup-state.json

How It Works / 工作原理

  1. Decrypt config via GPG (or read plaintext fallback) / GPG 解密配置
  2. Collect workspace, configs, strategies, skills into archives / 打包文件
  3. Upload to WebDAV via --netrc-file (credentials never in process listings) / 上传到 WebDAV
  4. Rotate — keep N newest, delete oldest (FIFO) / 轮转：保留最新 N 个
  5. Clean up — all temp files removed on exit / 退出时清理临时文件

Security / 安全

  • GPG AES-256 encrypted credential storage / 凭证加密存储
  • --netrc-file for all curl calls (backup + restore) — no -u user:pass / 所有 curl 调用使用 netrc
  • HTTPS warning if WebDAV URL is not HTTPS / 非 HTTPS 警告
  • Channel auth excluded by default (configurable) / 默认排除通道认证 token
  • Temp cleanup via trap EXIT — netrc + archives removed even on failure / 异常退出也清理
  • Secret exclusion — .gpg, .key, .secret, .env always excluded / 始终排除密钥文件

What Gets Backed Up / 备份内容

Component / 组件Includes / 包含Excludes / 排除
WorkspaceMemory, docs, scripts.git, node_modules, venv, .env, secrets/*.gpg
Configopenclaw.json, cron/Channel auth (default), *.gpg, *.secret
StrategiesStrategy files, monitorsvenv, pycache
SkillsInstalled skill packagesnode_modules, venv, *.gpg

Cron / 定时备份

Setup wizard prints the cron command (does not auto-create). Add manually:

配置向导打印 cron 命令（不会自动创建）。手动添加：

# Every 3 days at 03:00 / 每 3 天凌晨 3 点
openclaw cron add --name "🌑 Mjolnir Shadow" \
  --schedule "0 3 */3 * *" --tz "Asia/Shanghai" \
  --isolated --timeout 300 \
  --message "bash /path/to/scripts/backup.sh"

Non-interactive GPG decryption / 非交互式 GPG 解密

For unattended cron runs, use gpg-agent (recommended) or set MJOLNIR_SHADOW_PASS via a secure secret store — do NOT put plaintext passphrases in cron commands or world-readable files.

非交互运行时，推荐使用 gpg-agent，或通过 安全的密钥存储 设置 MJOLNIR_SHADOW_PASS — 不要 在 cron 命令或明文文件中写入密码。

# Recommended: use gpg-agent (pre-cache passphrase)
# 推荐：使用 gpg-agent（预缓存密码）
gpg-connect-agent /bye  # ensure agent is running

# Alternative: read from encrypted credential store
# 备选：从加密凭证存储读取
# export MJOLNIR_SHADOW_PASS="$(your-secret-manager get mjolnir-shadow-pass)"

Restore / 恢复

🚀 一键恢复（推荐新手）

# 方式1: 全自动模式 — 带进度条，一键搞定
bash scripts/restore.sh --auto

# 方式2: 独立恢复引导 — 不依赖 OpenClaw，全新系统也能用
bash scripts/restore-kit.sh

--auto 模式会自动完成：解密配置 → 查找最新备份 → 下载 → 解压 → 恢复全部组件 → 重启 OpenClaw。全程进度条显示，小白友好。

restore-kit.sh 是完全独立的脚本，不依赖任何已安装技能。适用于：

  • 全新系统重装后恢复
  • OpenClaw 还没装的时候
  • 从另一台机器 SCP 过来直接运行
# 从另一台机器拷贝过来运行
scp kaixin:/path/to/restore-kit.sh . && bash restore-kit.sh

手动模式（高级用户）

bash scripts/restore.sh --list       # List backups / 列出备份
bash scripts/restore.sh --latest     # Restore latest (manual) / 恢复最新（手动确认）
bash scripts/restore.sh --file NAME  # Restore specific / 恢复指定

手动模式先解压到临时目录，你可以检查后再决定覆盖哪些组件。
