Exactly so.
My backup files look as these:
-rw-r--r-- 1 19K Feb 7 19:36 double-opt-in.el
-rw-r--r-- 1 19K Aug 11 2021 double-opt-in.el~
In reality I almost never use them.

Good idea.
I got tired of it all and made
Emacs: RCD Version Control system with PostgreSQL backend:
https://hyperscope.link/3/6/7/9/6/Emacs-RCD-Version-Control-system-with-PostgreSQL-backend-36796.html
And now it is all without thinking and my backup files I just recall
by using a function. Not as sophisticated, though very automatic.
A version of file is in the database. If I need it, I get it
back. Sometimes I do need to repair functions from past. If the file
name location change, I will still be able to find the file in the
database, or save it to file system from there.
