I have frequent kernel crashes (which I haven't solved, but that's another story) that absolutely destroy my Blender save files. If I have a file open in Blender, even if I'm not doing anything to it, it will be corrupted when I try to open it again after rebooting. I'll get the infamous "file format not supported" error and when I check the size of the .blend file, it's 0B.
I also have auto backups turned on, but when I went to check if they were any better, they were also 0B.
I'm not expecting to solve my kernel crashes, but is there a way to make sure these corruptions don't occur, outside of manually backing up my files every 5 minutes?
