Blender’s built-in autosave is designed for temporary crash recovery. Reliable Auto Save adds a second layer of protection by creating real, timestamped .blend backup files that you can open directly.

Set your interval, keep a rolling history, save only when the file has changed, and optionally create a backup right before a render starts. Controls are available in the 3D Viewport header and the AutoSave sidebar.

Key Features

• Real timestamped .blend backup files
• Adjustable autosave interval
• Rolling backup limit with automatic pruning
• Save only when the file has unsaved changes
• Optional backup before render
• Project-adjacent or custom backup folder
• Manual “Save Backup Now”
• Open Backup Folder shortcut
• Re-arm timer
• 3D Viewport header toggle and dropdown
• Full N-panel controls
• Non-destructive (never replaces your active file path)

Designed For

Long sessions, animation, simulations, modeling, sculpting, production work, and anyone who has lost hours of work to a crash.

Compatibility

• Blender 5.0 or newer
• Windows, macOS, and Linux
• No external dependencies

Important Note

The optional header button uses an experimental override and may conflict with other add-ons that modify the 3D View header. It can be disabled without affecting the rest of the addon.

Reliable Auto Save is a backup aid, not a replacement for normal saves, source control, or external backups.
