Sketchup not making backups

SU Pro 2019 on windows 10 Pro.
Backups are set, path is set, time interval is set. it just doesn’t do anything.
Ideas?

The time interval is for auto-save (aka, recovered) files. Backup and auto-save are different. When you have backup checked, it copies the current file to a back up file and then saves. Autosave saves every (choose your timeframe) specified timeframe.

Right. thanks for the clarification. But if I crash, there should be an autosave. And there isnt.

Auto-saved files are not saved in same directory as your original SketchUp model.

In SU 19.3 and 2020, auto-save files are stored in the following locations.

Mac
~/Library/Application Support/SketchUp (2019 or 2020)/working/SKETCHUP/RecoveredFiles

Win
C:\Users\YourUserName\AppData\Local\SketchUp\SketchUp 20xx\SketchUp\working\SKETCHUP\RecoveredFiles
