Please read the Emacs manual: when you make a drastic change, Emacs
disables auto-save (and tell you about that), until you re-enable it.

Please read the manual: Emacs places the auto-save files in the same
directory where the original file lives, so it won't be erased by
cleanup jobs. Emacs also automatically finds the auto-save file when
you visit the original file again, and suggests to recover the edits
from there.
