Emacs Numbered Backup Strategy

Emacs produces a backup of each file by default. It does this by appending a tilde to the file's name. For example, Myfile.txt is backed up to Myfile.txt~. It's a reasonable strategy, assuming that a Version Control system is in place.

But in the absence of version control, you're limited to restoring just the previous version; older versions need to be restored from backup.

I use git for coding projects that I share to the public. But I didn't create a repository for my home directory. So when C-c a m TAG¹ generated an error instead of a list of TAGged items, I hoped fervently that the latest init file change was to blame.

After finding and fixing the problem quickly, (and realizing I was lucky this time), I resolved to be more diligent about disaster recovery. I looked into what backup schemes Emacs already provides.

Emacs can create unique backups for a file rather than overwriting the previous backup. When Emacs sees a numbered backup for a given file, it will make a new, sequentially-named file for each backup of that file, while continuing to use the "append tilde" method for other files.

Once I renamed (or copied) .emacs~ to .emacs.~1~, Emacs created backups named .emacs.~2~, .emacs.~3~ (and so on). I didn't even need to change a variable -- when Emacs detected .emacs.~1~, it knew that backups of .emacs needed to be numeric, so it acted accordingly. Emacs continues to use bills.org~ as the backup for bills.org. Until I tell it otherwise.

Read the Emacs Manual to learn more about numbered backups.

The default values for the pertinent backup variables are:

• make-backup-files is t
• backup-by-copying is nil
• version-control is nil

How Much Management Does Knowledge Need?

The topic of this month's Emacs Carnival interests me, even though I "dump ... notes into a directory and simply grep for information ...."⁰ Org does not work the way my brain works,¹ or rather, my brain doesn't work the way Org works.

I do use Org. At first I created a few Org files (work.org and home.org, and maybe todo.org) thinking I could rigidly dedicate all my topics to them.

Over time I had about dozen files, one for nearly every major facet of my life until I gave up. Why? Because it really doesn't matter where I put Org TODOs and their notes. When I need to locate something, Org provides a way to search entries for a regular expression, which is what grep does, sans all that Unixy CLI stuff.

So faced with the task of paying one of my wife's medical bills, I could agonize over whether to put the task into wife.org or bills.org or medical.org.² Or I could just:

• establish the task somewhere,
• act on it
• link to a receipt
• mark it done³

I created a special template for org-capture, which places these one-off tasks into todo.org. And it clocks into the task, too.

A topic with even greater complexity is "education." I'm a lifelong learner; my edu.org file has (only) 29 headings, all of which have at least a few subheadings. If I learn about an Emacs feature, I might want to write about it, so I'll put a task into blog.org that links to it.

Occasionally a post will span multiple topics in edu.org, topics such as Emacs, Vivaldi, LibreOffice, HTML or LaTeX. In a year from now, which file should I look for it in? The keystroke C-c a s comes to the rescue.⁴ I might search for "Sacha" because all I remember is that I discovered an Emacs feature on Sacha's website.⁵ Incidentally, I get 13 hits when I search for "Sacha," one of which was the one I had in mind.

The question I think all Emacs users face is, "At what point does tweaking Emacs (and self-quantifying tools in general) tip the scales from aiding our progress to impeding it?" I dread going down a Knowledge Management rabbit hole,⁶ but I'm sure I'll enjoy the leap.

¹ A tree works like your brain.

² Don't even get me started on insurance.

³ All of this occurs while clocked in to the task.

⁴ In this case, C-c a is bound to org-agenda.

⁶ Can one gain knowledge of Knowledge Management Systems without having a Knowledge Management System in which to record that knowledge? That may be a Zen koan for someone.

Vakana -- Sneak a Peek

I installed Donovan Ratefison's brand-new Vakana app¹ on my Android device this morning. After following the tutorial, I exported the thread as an Org-mode-compatible package in a ZIP and emailed it to myself in order to transfer it to my desktop.

After opening the Org file that Vakana generated, I exported the entire buffer to HTML. The result is shown below. The only change I wanted to make was to scale the bead of each heading 25%.²

It's fortuitous that Donovan Ratefison released Vakana in a month whose Emacs Carnival theme is "The Search for Knowledge," because Vakana provides a unique way to manage one's knowledge. I'll need to become proficient in it before adding it to my workflow. So my eventual Emacs Carnival submission will be more pedestrian.

Welcome — and if this is all new, that’s perfectly fine. We’ll go gently.

Vakana is the Malagasy word for beads — there’s no other word for them in the language, and it’s where this app takes its name. The idea is old and simple: you turn a moment into a small bead — a little coloured token — and beads you keep together form a thread you can walk back along, like beads on a string. (These six notes are already a thread — “Your first thread.”)

That’s the whole shape of it. What a bead means is always yours — the app never decides that for you.

This is a short, hands-on tour: five steps, each one a thing you try yourself.

Next → 1/5 · Tap the bead.

3. 1/5 · Tap the bead

[2026-08-08 Sat]

,*Tap the bead* at the top of this note — the composer opens. That’s where you pick a bead’s shape, pattern, mood-colour and a tiny glyph (this one’s is the number 1️⃣).

Eight shapes, eight patterns, eight moods — small enough to learn, wide enough for anything. There’s no legend: a circle isn’t “an encounter” unless you decide it is.

How does the user navigate the beads? Now I see "< Prev" and "Next >" so it's obvious.

Next → 2/5 · Open the thread.

4. 2/5 · Open the thread

[2026-08-07 Fri]

You’re on a thread right now — a chain of beads strung together on purpose. Open “Your first thread” (tap its chip here, or find it in the Threads view) and you’ll see all six beads in a row you can walk, bead by bead.

The app also keeps a quiet thread for every day you write, under Days in the Threads view — built for you, no effort.

Next → 3/5 · Comment.

5. 3/5 · Comment — swipe me right

[2026-08-06 Thu]

Some thoughts arrive after the moment. Instead of rewriting a note, leave a comment in its margin.

Try it: tap the 💬 at the top of this note — or, back in your list, swipe this row to the right. Either opens the margin, where you can jot a thought or even set it to remind you later.

(The next bead, 4️⃣, already has a comment — spot the 💬 on its row.)

Next → 4/5 · Long-press the bead.

5.1. Comments

5.1.1. Comment — [2026-08-09 Sun 18:50]

The tutorial shows an icon for comment as a white-filled rectangular balloon with three dots. However the actual icon is a balloon that's an empty circle

6. 4/5 · Long-press a bead in the list

[2026-08-05 Wed]

Beads repeat, and you’ll want to find a bead’s kin. This is a thing you do from your list, not from inside a note — so head back to the list first.

There, press and hold any bead: the list instantly filters to every bead like it. (Long-press is the move most people miss.)

Want finer control? Tap the funnel at the top of the list to filter by shape, mood, pattern or glyph, then gather the results into a brand-new thread.

Next → 5/5 · Make it yours.

6.1. Comments

6.1.1. Comment — [2026-08-09 Sun 18:22]

I keep coming back to this one — long-pressing a bead is the move most people miss.

6.1.2. Comment — [2026-08-09 Sun 19:14]

The alarm clock icon next to the note field is for a reminder, not a timestamp. It puts it on the next business day at 9:00 a.m., perhaps. I pressed it at 3:00 p.m. on Sunday August 9th, and then entered the reminder for the next day at 9:00 a.m..

7. 5/5 · Close it, then make it yours

[2026-08-04 Tue]

This thread is closed — notice the clasp. Closing marks a loop that finished; you can reopen it anytime.

A finished thread can leave the app: open it and Export to turn it into a web page or a slide deck.

That’s the whole grammar — bead, thread, comment, close, export. Now make it yours:

• Delete this tour — swipe any note left, or remove it in one tap from Settings → Pro Tips → Interactive tutorial. • Want it back later? Reload from the same place.

Now write your first real moment, and bead it however you like.
