Re: Auto-generated backup files: are they useful?


JP, I agree that true backups are useful.

Maybe even it is a good idea for KiCad to have a built-in backup function.

I just don't think the current backup function is actually useful
because of my first point (backups are overwritten on each save).

I would propose:

1) Remove the current backup file generation

2) Create a spec (in GitLab issue) for a better backup system that:

- Can be turned on or off
- Backs up the whole project in a zip file
- Can keep the last N backups
- Runs on a schedule, not necessarily every time you click Save.

Anyone opposed to this?
