It appears you cannot back up and restore older notebook versions using computer.

This worked:
- copy notebook folder to computer
- remove notebook folder from Scribe
- disconnect usb and sync (download is gone)
- connect usb and copy notebook folder back
- disconnect usb
- download is restored

This didn't work:
- copy notebook folder
- disconnect usb
- make a change to notebook and sync
- remove download
- connect usb
- copy previous notebook folder to scribe
- disconnect usb
- no download shown, it ignores older version

So to backup a version, it looks like you need to make a copy that also gets saved to cloud.
