====================================

Choose an option:
  1. Run Backup (Git)
  2. Run Backup (Archive)
  3. List Available Backups
  4. Rollback to Previous
  5. Install/Setup
  6. Exit

This menu:

• ✅ No command-line knowledge needed
• ✅ Returns to menu after each operation
• ✅ Perfect for daily use
• ✅ Works by double-clicking the file

For restore operations, double-click QuickRestore.bat for a guided restore process.

Interactive Installation (For First-Time Setup)

Run the install wizard for automated setup:

Via Menu:

1. Right-click RunBackup.bat → Run as Administrator ⚠️
2. Choose option 5 (Install/Setup)

Via PowerShell (Run as Administrator):

.\ComfyUI-Backup.ps1 -Mode Install

⚠️ Important Notes:

• Administrator privileges required for creating scheduled tasks
• Time format must be HH:mm (24-hour format with colon)
  • ✅ Correct: 02:00, 14:30, 23:45
  • ❌ Incorrect: 2:00, 2am, 14.30

This will:

1. Let you choose Git or Archive backup
2. Set backup schedule time (must be in HH:mm format)
3. Create scheduled task (runs automatically at specified time)
4. Create Start Menu shortcut (for manual backups)
5. Perform initial backup

What gets created:

• Scheduled Task: Runs backup automatically daily at your chosen time
• Start Menu Shortcut: Found in Start Menu → "ComfyUI Backup" (for running manual backups)
• Note: Does NOT add to Windows Startup folder (backups run via scheduled task instead)

Requirements

• Windows 10/11
• PowerShell 5.1 or higher
• Git for Windows (only if using Git backup type)

Git vs Archive Backup

Git Backup (Recommended)

✅ Unlimited restore points ✅ Space-efficient (stores only changes) ✅ View full history ✅ Fast rollback ❌ Requires Git installation

Archive Backup

✅ Simple ZIP files ✅ No dependencies ✅ Easy to understand ❌ More disk space ❌ Limited to recent backups (14 days)

Safety Features

• Creates safety backup before any restore operation
• Safety backups stored in %TEMP%\ComfyUI-PreRestore_*
• Automatic cleanup of old backups
• Git history pruning (keeps last 30 commits)
• Archive rotation (keeps last 14 days)

Troubleshooting

"Execution of scripts is disabled on this system"

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

"Access denied" when creating scheduled task

• Solution: Right-click RunBackup.bat → Run as Administrator
• Or run PowerShell as Administrator before executing commands
• Scheduled tasks require admin privileges to create

Scheduled task not created during Install

• Make sure you ran the batch file or PowerShell as Administrator
• Check Task Scheduler (Win+R → taskschd.msc) to see if task exists
• Task name: "ComfyUI-DailyBackup"

Invalid time format error

• Time must be in HH:mm format (24-hour with colon)
• Examples: 02:00, 14:30, 23:00
• NOT: 2:00, 2am, 14.30

Git not found

• Install Git for Windows: https://git-scm.com/download/win
• Or use -BackupType Archive instead

Source path not found

• Verify ComfyUI Electron is installed at: %LOCALAPPDATA%\Programs\@comfyorgcomfyui-electron

Can't find Start Menu shortcut

• Look in Start Menu search for "ComfyUI Backup"
• Located at: %APPDATA%\Microsoft\Windows\Start Menu\Programs\ComfyUI Backup.lnk
• Note: This is for manual backups, NOT automatic startup
• Automatic backups run via Windows Task Scheduler

"Cannot rollback: Only 1 commit(s) in history"

• Rollback requires at least 2 commits to restore from the previous one
• Solution: Run a backup first to create a second commit
• Then rollback will restore to the state before that backup
• First backup creates initial snapshot; second backup allows rollback to first

Examples

Daily automated Git backups at 2 AM:

• Right-click RunBackup.bat → Run as Administrator
• Choose option 5 (Install/Setup)
• Select Git backup (option 1)
• Enter time: 02:00 (must include colon in HH:mm format)

Manual backup before major changes:

• Double-click RunBackup.bat
• Choose option 1 (Git) or 2 (Archive)

Restore after something breaks:

• Double-click QuickRestore.bat
• View available backups
• Choose restore method
• Follow the prompts

Advanced PowerShell examples:

# List backups
.\ComfyUI-Backup.ps1 -Mode ListBackups

# Restore specific commit
.\ComfyUI-Backup.ps1 -Mode Restore -BackupType Git -RestorePoint a1b2c3d

# Or just rollback to previous
.\ComfyUI-Backup.ps1 -Mode Rollback -BackupType Git

Logs

Logs are stored in Logs\ComfyUI-Backup_YYYY-MM.log with detailed information about all operations.
