Update (2026-03-12): After hearing good things about restic, I added it to my backup strategy.
Prior to Omarchy, I was a Mac user for 15 years. I used Time Machine to back up my system to an external drive and, every few years when I got a new Mac, I would do a fresh install and download and reconfigure all my apps.
But as time went by, it became more and more tedious to configure new machines as I accumulated all sorts of undocumented little tweaks and settings. So I ended up relying exclusively on Time Machine and felt my setup was accumulating cruft.
With Omarchy, I was inspired by DHH’s philosophy of a stateless, disposable machine (see No backup, no cry). Instead of relying on a full-disk backup, I wanted to set things up so that I could spin up a new machine and have it ready within an hour.
This is the first of a series of two posts where I cover my backup strategy. It relies on Dropbox, Git, yadm, restic, and a few Bash install scripts.
1. Syncing documents with Dropbox
Dropbox is one of the few big syncing providers that has native support for Linux. In fact, it’s the solution DHH uses himself and it can easily be installed from the Install > Service > Dropbox menu.
I use it to back up all my personal files and documents that are not Git projects.
I assume Linux users don’t need a tutorial on how to configure Dropbox. But a small tweak that I find quite useful is to create symlinks from my Dropbox folders to my home directory.
For example, if you have a Documents folder in Dropbox, you can symlink it this way:
ln -s ~/Dropbox/Documents ~/Documents2. Syncing projects with Git
Well, this is another one that does not need explaining. All my Git projects are in the ~/Work directory and are synced as long as I don’t forget to push the latest changes to GitHub!
3. Syncing config files with yadm
When it comes to syncing config files, the three popular solutions I came across are stow, yadm and chezmoi.
I first tried stow after watching Typecraft’s YouTube video raving about it. I just could not make it work the way I wanted. I would get tangled in all these symlink files and the commands did not feel intuitive.
I read about chezmoi but it felt a bit too much for what I needed. I didn’t give it a proper shot and I know plenty of Linux users are happy with this solution.
I ended up choosing yadm, which is lightweight and works with plain Git commands. It treats your home folder like a Git repository and adds some niceties on top of it. You can encrypt files and use per-machine configurations. Overall it’s just like managing a Git repository that you can push to GitHub, except that you use the yadm command instead of git.
My main use case for yadm is syncing config files across my two laptops. I have a few dotfiles that I want to keep in sync, and yadm makes it easy to do so.
Another use case is to keep track files affected by Omarchy updates. Technically, Omarchy should leave your dotfiles alone, but that’s not always the case and I want to know what changed.
I use yadm so much that I ended up creating a y alias in my .bashrc file to not have to type the full 4 characters!
alias y=yadm~/.bashrc4. Backing up my .config with restic
After hearing good things about restic, I added it to my backup strategy as well.
I use it for a complete backup of my .config directory to an S3 bucket. That gives me an extra layer of protection beyond yadm, since it also covers config files and application state that I do not explicitly track in Git.
The backup runs automatically every day through a systemd timer unit, so once it is set up I do not need to think about it.
I found it was easy to set up using codex but any agentic AI would work.
5. Owning a secondary machine
Since I contribute to Omarchy’s development, I’m running my laptop on the dev channel. So far, everything has been running smoothly.
But Arch Linux being a rolling release distro, you need to understand that things could go bad. That’s one reason why I have a secondary machine just in case. This machine runs on the stable channel and is kept in sync with my primary machine.
Part 2 - Apps and services
In Part 2, I’ll show you how I manage setting up a new machine in just a few minutes with Bash scripts. I was heavily inspired by the way Omarchy works under the hood.
