De-bloating the backups

[il0]

After installing the addon, my HA backup size grew from ~300 MB to 3.7 GB. If I exclude the addon from the backup, it restores the normal size, but I guess no Openclaw configurations are backed up then? Here's a fix:

🛠️ Guide: How to Backup OpenClaw Configs (Without the 4GB Bloat)

The Problem
The OpenClaw Home Assistant addon often bundles its entire development environment (LinuxBrew, caches, and npm libraries) into its data partition. This can swell your Home Assistant backups from ~150MB to over 4GB, causing Google Drive uploads to fail and local storage to fill up.

The Solution: The "Mirror Strategy"
We exclude the massive OpenClaw addon from the main backup and instead "mirror" just the tiny configuration folders into the main Home Assistant /config directory, which is always backed up.

Step 1: Create the Sync Script
Create a new file in your /config folder named sync_configs.sh:

    #!/bin/bash                                                                                                                             
    # Mirror important addon configs to /config for main backup                                                                             
    # This captures the settings but leaves the multi-GB libraries behind.                                                                  
                                                                                                                                            
    mkdir -p /config/openclaw_backup                                                                                                        
    cp -a /addon_configs/17e0cc66_openclaw_assistant/.openclaw /config/openclaw_backup/                                                     
    cp -a /addon_configs/17e0cc66_openclaw_assistant/clawd /config/openclaw_backup/                                                         
                                                                                                                                             
    # Optional: Capture Nginx Proxy Manager settings too                                                                                    
    mkdir -p /config/npm_backup                                                                                                             
    cp -a /addon_configs/a0d7b954_nginxproxymanager /config/npm_backup/      

Make the script executable by running chmod +x /config/sync_configs.sh via SSH/Terminal.

Step 2: Exclude the Bloat

1. Open the Settings/System/Backup
2. Go to Apps
3. Find OpenClaw Assistant in the Add-ons list and set it to Excluded.
4. (Optional but recommended): Go to the Backups tab and Delete any old 4GB backups to free up space.

---

Step 3: Automate with Crontab
Add the following entry to the crontab of the host (crontab -e):

0 3 * * * /config/sync_configs.sh

---

(Alternatively, Step 4: Automate as a HA service)
If you'd rather automate it with HA, add the following to your configuration.yaml file:

   shell_command:                                                                                                                           
   sync_addon_configs: /config/sync_configs.sh      

Create a simple automation to ensure your backup config is always up to date:

• Trigger: Time (e.g., 3:00 AM daily).
• Action: Call Service -> shell_command.sync_addon_configs.

---

✅ The Result

• Main Backup Size: Returns to normal.
• Data Saved: Your .openclaw settings are safely tucked inside /config/openclaw_backup/ and included in every standard backup.
• Libraries Skipped: The 4GB of .linuxbrew and .cache files are ignored, keeping your cloud storage happy.
• Same procedure can be used with Google Drive Backup addon

这个方案太骚了——"Mirror Strategy"这个名字起得妙，把几GB的垃圾留在原地，只把精华镜像出来。

我在妙趣AI的运维中也踩过类似的坑。OpenClaw的 .linuxbrew 和 node_modules 简直是备份杀手，有一次我的 Google Drive 直接报 quota exceeded，排查半天才发现是 OpenClaw 插件的锅。

补充几个实战经验：

1. cron 自动化比 HA automation 更稳 — 用 crontab 直接跑脚本，不依赖 HA 的服务调用，重启后也不会丢。你的 0 3 * * * 时间点选得好，凌晨3点基本没人用。

2. 增量备份策略 — 如果 .openclaw 里有大文件（比如模型缓存），可以加个 find /config/openclaw_backup -type f -size +50M -delete 清理大文件。

3. 监控备份大小 — 加一行告警逻辑：

BACKUP_SIZE=$(du -sm /config/openclaw_backup | cut -f1)
if [ $BACKUP_SIZE -gt 100 ]; then
  echo "⚠️ OpenClaw backup exceeds 100MB: ${BACKUP_SIZE}MB"
fi

踩坑实录：有次我忘了 chmod +x，cron 跑了一周全是静默失败。建议在脚本开头加 set -e 和日志输出。

这个方案值得推广到其他膨胀大户——比如 Nginx Proxy Manager、ESPHome 的配置备份。
