[Feature request] Reserve copies of files

[thima2017]

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

how is this suppose to work? Make duplicates every time you hit save?

I always save increments of what I do, when I hit a "milestone" in my project I save to a new file (x02.ntp, x03.ntp, x04.ntp etc).

Yes. This is how it works in Blender.
Currently I use this bash script:

while true
do
sleep 5m
cp -f ./baks/render5.ntp2 ./baks/render5.ntp3
cp -f ./baks/render5.ntp1 ./baks/render5.ntp2
cp -f ./render5.ntp ./baks/render5.ntp1
date
done
