Does SketchUp Pro make backups?

Yes, you can set it up at:

Windows: Window > Preferences > General

Mac: SketchUp > Preferences > General

1. Create Backup

SketchUp creates a backup file every time you have saved your SketchUp file successfully. This file is an exact copy of the previously saved version of the file. The backup file uses the same name ("NAME.skb" on Windows and "NAME~.skp" on Mac macOS) and is in the same folder as the original file..

2. Auto-save

SketchUp automatically saves you files every five minutes. If your file is called MyDrawing.skp, then SketchUp saves a file named MyDrawing.skp in the folder 'working'. This auto save file is different from the backup file from 1. above.

So while working on a model, you can have three files: .skp (the original file), the backup file (.skb or ~ .skp), and the auto-save file (.skp), in the 'working' folder.

The auto-save files are saved until you successfully save your original file yourself. So if SketchUp crashes while you're working, your auto save file will not be deleted. You can therefore continue working from the point of the last auto-save.

You will find the autosave files here:
