- 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.
So I am thinking about this some more.

It seems Kindles think they are in London. Download something and it displays creation time that's in future with respect to local time (+8h for me).

So maybe to restore previous version you need to change the modify time(s) (mtime) so it is greater than create time (ctime)? So it thinks you have an update? I'll try it.

I also tried changing the folder guid to see if Scribe would at least open it. That alone is not enough, but maybe it is again issue with timestamp.

It would be nice to have some way to have a 'local', non-cloud backup that would allow restore of a specific version, and if it would let you supply your own guid's you could effectively side load notebooks that would not be in cloud.

But I suspect the guid has to be one associated with your account.

Even if that's the case, if it's possible to execute scenario #2 by mucking with mtime, it might be useful for people with privacy concerns: you generate as many empty notebooks as you like (in the folders you want them to reside in), work with those with WiFi off, and if you need to go online just move them off kindle so they never sync to cloud, restore after going offline. A PITA but some automation could help with it.
