🛡️ ComfyUI Workflow Backup

A custom node for ComfyUI that allows you to backup your current workflow (API format) and all the models used in it to a specific destination (Local or External Drives).

✨ Features

• 💾 Full Backup: Saves the workflow .json and copies all necessary models (Checkpoints, LoRAs, VAEs, etc.).
• 🔒 Enterprise Security: Includes a path sanitizer and a whitelist system to prevent unauthorized file system access.
• 📂 External Drive Support: Safely backup to USB drives, NAS, or secondary hard drives using the whitelist configuration.
• 📊 Analysis Mode: Preview which files will be copied and the total size before executing the backup.
• 🌎 Bilingual: Output logs available in English and Spanish.

⚙️ Configuration (Crucial Step!)

To comply with strict security standards, this node blocks write access to external drives by default.

To allow backups to external drives (e.g., D:/, E:/, /mnt/), you must create a configuration file manually:

1. Go to the node directory: ComfyUI/custom_nodes/ComfyUI-Workflow-Backup/
2. Workflows Path: Paste the specific folder where your .json workflows are located (e.g., ComfyUI/user/default/workflows).
   • ⚠️ Tip: Do not use the root ComfyUI folder, or the node will try to scan system files and show warnings.
3. Add the allowed root folders inside using the JSON format below.

Example extra_paths.json:

{
    "allowed_paths": [
        "D:/ComfyUI_Backup",
        "E:/MyExternalDrive",
        "/mnt/backups"
    ]
}
⚠️ Note: If extra_paths.json is missing or the destination path is not whitelisted, the node will force the backup to be saved inside the standard ComfyUI/output/workflow_backups folder.

## 📦 Installation

**Via ComfyUI Manager:**
* Search for `Workflow Backup` in the Manager and click **Install**.

**Manual Installation:**
1. Go to your `custom_nodes` folder.
2. Run: `git clone https://github.com/zavatmotion/ComfyUI-Workflow-Backup.git`
3. Restart ComfyUI.

## 🚀 How to Use

**Quick Start:** You can load the included `Models-Backup.json` workflow file to get started immediately.

1.  Add the node **"Workflow Backup"** (Category: `utils/backup`).
2.  **Workflows Path:** Paste the **specific folder** where your `.json` workflows are located (e.g., `ComfyUI/user/default/workflows`).
    * *⚠️ Tip: Do not use the root `ComfyUI` folder to avoid scanning system files.*
3.  **Backup Destination:** Choose where to save the backup.
    * *Remember: If you want to use an external drive, you must add it to `extra_paths.json` first.*
4.  **Mode:**
    * `ANALYSIS_ONLY`: Checks files and calculates size (Safe mode).
    * `EXECUTE_BACKUP`: Performs the actual copy.
