How Do I Backup a DWG File?

The primary way to automatically backup your DWG files in AutoCAD is by enabling the built-in backup feature, which creates a backup copy (.BAK) every time you save your drawing.

Enabling Automatic DWG Backups in AutoCAD

AutoCAD offers a simple setting to ensure you have a backup copy of your drawing created automatically with each save. This backup file is typically the version of your drawing from the previous save.

Here's how to activate this essential backup feature based on the provided information:

1. Click “Options” in AutoCAD.
2. Select the “Open and Save” tab in the Options dialog box.
3. Check the “Create backup copy with each save” option.

Once this option is enabled, whenever you save your drawing, AutoCAD will automatically create a backup file with the .bak extension in the same folder as your original .dwg file.

Understanding the AutoCAD Backup File (.BAK)

• The .bak file is a copy of your drawing before the most recent save.
• It shares the same base name as your drawing file (e.g., MyDrawing.dwg will have MyDrawing.bak).
• To restore a .bak file, you simply locate the file in your file explorer, right-click on it, and rename the extension from .bak to .dwg. You can then open this renamed file in AutoCAD.

Benefits of Using This Feature:

• Simple Activation: Just a few clicks in the settings.
• Automatic Process: Requires no manual effort after setup.
• Quick Recovery: Provides an easily accessible previous version if your current file becomes corrupt or you need to revert recent changes.

While this method provides a local backup of your previous save, it's important to note that comprehensive data backup strategies often involve additional methods like saving to cloud storage, using version control systems, or regular manual copies to external drives. However, enabling the .bak creation is a crucial first step for protecting your ongoing work within AutoCAD.
