impermanence VS aconfmgr

I would not call these projects unbelievable, but they are neat.

- Opt-in state: https://github.com/nix-community/impermanence and https://grahamc.com/blog/erase-your-darlings/

That way will work - I use the impermanence module which works similarly but allows to hide mounts.

This is indeed a blind spot. Thanks for pointing that out! Silverblue -to my knowledge- doesn't do a lot to address this. Though, 3rd-party tools like Home Manager and the suite of applications developed by the folks over at uBlue might be able to limit this to a minimum. Though I'm not sure if it surpasses NixOS in this regard; for the uninitiated. Though, to my knowledge, this requires special attention and depends on the specifics of the NixOS system in question.

I have recently stumbled upon Impermanence - modules to help you handle persistent state on systems with ephemeral root storage, and the concept seems quite nice.

I haven't used it yet but nix-community/impermanence has a home-manager module that might be useful.

Some files in /etc (like saved networks) will still not be managed by NixOS, if you want to have full control over them use Impermanence

{ imports = [ (modulesPath + "/installer/scan/not-detected.nix") "${builtins.fetchGit { url = "https://github.com/NixOS/nixos-hardware.git"; }}/system76" "${builtins.fetchGit { url = "https://github.com/nix-community/impermanence.git"; }}/nixos.nix" ];

There is a maintained collection of modules for running this kind of NixOS setup. It's called impermanence.

Establishing a backup strategy. I'm using BTRFS with snapper and a pacman hook that creates a new snapshot before each upgrade. With ext4 I used timeshift. Besides that, I save my arch configuration with aconfmgr and my files with borg

Since my last cloning I've setup aconfmgr and and systemd-homed. I've also been playing around with archinstall configs to partition the system with encryption how I like. In the future I'm planning to use archinstall and aconfmgr to setup a new system for me and then I'll copy over the backup of my home directory.

Have you tried aconfmgr? In addition to installing packages, it also tracks configurations in /etc and modified files.

For my backup I keep files in my home directory synced with my NAS via syncthing. For my system backup I don't actually backup up my system, I configure my system via aconfmgr and that config is stored in my home directory and synced to my NAS. Using aconfmgr to "backup" my system is extremely space effecient, my aconfmgr config is only 1.7 MB.

aconfmgr (in AUR) can be used to save and restore system configurations and installed packages. For user configuration you can use a dotfile manager like chezmoi (in repo).

I know you prefer backing up manually, but aconfmgr might be for you.

To get something closer to nix on arch I like to use aconfmgr.

For those who are not familiar with Arch's aconfmgr, well I have not used it before but just saw it in a post. But it seems to be a configuration manager for Arch. It tracks, manages, and restores your Arch Linux OS configuration.
