I'm on 2.93.2 LTS, working on a large Archviz scene.
Autosave is set to 1 minute, which is probably why that darn thing is so badly responsive, plus my prior lack of knowledge & thought about externally linking files instead of appending everything.
BUT: many times, when Blender crashes, there is no autosave file. And if there is, it's frequently causing a crash upon saving, maybe because I'm active doing something in the meanwhile, but never within 1 minute intervals - luckily, as the darn thing is 5 GB in size due to my n00bness.
What would be the wisest way to prevent such behaviour?
