- Save your stuff before a “dangerous” operation. If it turns out badly and [Ctrl + Z] does not work, you can always still just exit KiCad without saving (But making a backup beforehand is a better option).
- If you make a backup every now and then, it gives you ease of mind, and you have more incentive to do a “dangerous” operation. The worst that can happen is that you lost your time between the last backup and when *&^%$#@! happens.
