Problem

My 2 hours work is lost because I have a bad computer or something (it just turned off). My Natron file I was working on is 0 kb now.

Expected behavior:

I expected to find any of a previous versions in a cache or somewhere.

Actual behavior:

I don't find any way to recover any part of my work.
I guess Natron should have something like this (screenshot from Blender Preferences > File & Load. It makes Blender to save a copies of the current file in the same directory with the original file):

Versions

• Natron version/commit (they can be retrieved from the About Window): Natron version 2.3.15 Release.
• OS version: Ubuntu 20.04
