-* Introduction
+* Basic Configuration
 New way to display line-numbers. I set mine to =relative= so that I can easily jump up and down by that value. Set this to =nil= to turn off, or =t= to be absolute.

-As [[https://tecosaur.github.io/emacs-config/config.html][tec wrote]], I want to use =~/.authsource.gpg= as I don’t want to accidentaly purge this file cleaning =~/.emacs.d=, and let's cache as much as possible, as my home machine is pretty safe, and my laptop is shutdown a lot.
+As [[https://philjackson.github.io//emacs/backups/2022/01/31/keeping-backups-of-every-edited-file/][Phil Jackson]] mentioned, Emacs has a lot of file backup strategy, and either change the [[help:backup-directory-alist][backup-directory-alist]] to put individual file backups elsewhere, e.g.
+
+#+BEGIN_SRC emacs-lisp :tangle no
+  (setq backup-directory-alist `(("." . "~/.backups")))
+#+END_SRC
+
+Or leave them in the current directory, but create an alias to =ls= to normally not see them, e.g.
+
+#+BEGIN_SRC sh
+  alias ls="ls --color=auto --hide='*~'"
+#+END_SRC
+
+I'm leaving them side-by-side, but I am keeping some extra copies:
+#+BEGIN_SRC emacs-lisp
+  (setq auto-save-default t
+        delete-old-versions t
+        kept-new-versions 6
+        kept-old-versions 2
+        version-control t)
+#+END_SRC
+The [[help:version-control][version-control]] variable affect backups (not some sort of global VC setting), this makes numeric backups.

Also, as [[https://www.bytedude.com/gpg-in-emacs/][bytedude]] mentions, I need to se the =epa-pineentry-mode= to =loopback= to actually get a prompt for the password, instead of an error.
