Arch Linux is an RPG. You bite the bullet and install it, despite your friends warning you that it's going to eat SO MUCH of your free time. Your girlfriend is confused by it, but she's glad you're enjoying yourself...at least when you're not yelling at the screen. Character creation is insane. You spend your first day customizing and don't actually do anything productive. Your coworkers are tired of you talking about it. They run Ubuntu. Casuals. Your boss is tired of losing productivity hours to it. And, periodically, you fight a big boss called "Oh shoot, this update did something bad, I should have paid attention". Pretty sure that's a callback to a world boss in Guild Wars 2, but I could be wrong.

@@driden1987 It really is a rabbit hole. I realized that snapper works flawless on openSUSE and other distros have some problems with it, so I get why ppl use Timeshift instead of snapper.

Timeshift-autosnap does the same. I have automatic snapshots every time I do yay -Syu. What do you prefer about snapper? I’m a beginner Linux user and timeshift does all I need from it, so I’m curious what else is there.

[@nico1337]

Small correction: At 16:38 you said grub-btrfsd picked up the change but in fact the grub reconfiguration here is done by the pacman hook from timeshift-autosnap. As you can see at 15:40 you have set updateGrub=true

[@HowToLinux]

I hate to admit it, but I noticed a very big speed difference in pacman between btrfs and ext4. Some time ago I was setting up Arch on WSL, and it was just blazing fast. With BTRFS it is like 2-3x slower even when no snapshots are made and the FS is balanced.

[@MrVampify]

It has a really steep learning curve but nixos would solve this forever and give you magic sysadmin powers should you keep a pure config.

[@dr_regularlove]

Lots of people have already mentioned it, but last year I switched to NixOS after having broke my Arch install for the last time. There's a learning curve, it's quite different from any other Linux distro, but the benefits are absolutely worth it. And you can use it like a rolling release when you want the latest packages, or pin packages to specific versions when you want, you are in complete control.

[@dr_regularlove]

Oh and one thing I might add, if you do look into NixOS, also look into a thing called Snowfall, which provides a set of conventions for writing your NixOS config, which is otherwise very open-ended which makes things a little harder to learn IMO, since you can organize your config into modules a thousand different ways and every other NixOS config you come across will be doing things its own way. I intend to rewrite my NixOS config using Snowfall lib at some point in the future.

[@giovannimazzocco499]

Amazing tutorial. That basically enables NixOS-like rollback capabilities on any Linux system. Great stuff!

[@typecraft_dev]

Hey thanks!

[@stephenbelikoff2185]

Why not just set up a crontab for checking for new snapshots and updating GRUB? The easiest way to do this is if the timeshift --check command returns true in a root crontab, also update the grub-btrfs snapshot registry. No need for an additional service or some seedy package that's able to view the file system.

[@ml_serenity]

The more control you have - the easier it's to step on your own tail. That's especially true with Arch.

[@wcrb15]

Time shift is a lifesaver. At my previous job they let me use Arch and my computer shut down in the middle of an update and it screwed everything 😂 I ended up having to reinstall everything. That was the day I became diligent about using time shift

Why would i schedule a daily snapshot if ive hooked up the 'take snapshot before update'? The only time ive ever broken my install was after an update. Also i used to update daily.

[@oalfodr]

Why were you doing partial upgrade?

[@yurtlew2280]

Exactly the reason why i just install Garuda since it has BTRFS and grub snapshots out of the box..snapshots with Arch is must for me, just in case something weird happens. I usually only update on the frist of the month as well.

[@anix3923]

I prefer to use the cli for rollback, because GUIs can be unreliable (although I don't mind them). I mainly use this bundle: Snapper + grub-btrfs + snapper-rollback (which works for the recommended layout of the btrfs file system on Arch Linux) + snap-pac

[@donaldmickunas8552]

FYI timeshift also has a terminal version. I've rolled by to a previous snapshot many times using it. It goes to show how many times I have screwed it up. Not so much any more.

[@liteflow10]

I tried to test this system and got super confused. I setup new arch. Installed a bunch of soft like in vid, configured it. Finally when i wanted to test i snapshoted system without neofetch, and after installed it. I booted with my created snapshot but it still was there. I tried to do thing like that to understand why do snapshots changes with the main system but got nothing. At the end i got a problem that system couldnt mount my home dir for some reason. Still cant resolve it

[@ygvanz]

Ran into the same issue. Had to reinstall Arch again...

[@liteflow10]

@@ygvanz you need to NOT include home dir to snapshots because @home's id change every time u backup. Thats why system cant mount it. I got 1 more issue that after first backup u will be forced to use one of your snapshots. But what will happen if your snap will automatically deleted by for example limit of snaps? So i just switched to nixos

[@StefanReddig]

Hi, I ran in the same issue! Here is a little fix: - in emergency mode enter your password - open your fstab file with your prefered editor and delete the entries with "subvolid=xxx" - reboot I don't know if it's a clean solution, but it works for me. there is also the possibility to mount your /home directory manually: - in emergency mode enter your password - identify your Btrfs device-/partitionname with "lsblk -f" - mount your subvolume with "mount -o subvol=@home /dev/"your device- or partitionname" /home" I think it is because timeshift ID's are distributed and these are not included in the fstab file. For more details see also the command “btrfs subvolume list /mnt” first entries.

[@leanghok120]

[@ranahussain8599]

These settings are great and you explained very well, but I want to say here there is one Linux OS which comes with all the setting to do the snapshot for your system out of the box. It is OpenSuse Tumbleweed. Great video though. Keep up the good work nerd.

[@RockTheCage55]

Just curious do you use any of the redundancy features of BTRFS. I have mostly stayed away from BTRFS because of the write-hole bug but i guess if you strear clear of Raid 56 you should be fine. Anyways this setup was cool & very helpful thanks (& you need it with Arch BTW 😝)

[@SashikaSandeepa]

Oh... Then what are the options come when I press shift key while booting . it shows different kernal versions to boot from I through they are enough for the system. Please someone explain

[@donaldmickunas8552]

Every time the kernel is updated on your system, the record of the previous version still exists on your system. That press shift while booting feature is probably provided by your computer manufacturer. It's purpose is for the rare chance that a new kernel doesn't work at intended. This makes it easier to change to an older kernel.

[@SashikaSandeepa]

@@donaldmickunas8552 appreciate man. But shift key thing isn't from computer manufacturer, it is from grub

[@Barakatic]

That will not work if your kernel update is generated on /boot partition on non Btrfs (e.g, an ESP). To recover from the previous snapshot, you should also have backup for /boot partition. Otherwise, you will have panic kernel after recovery.

[@frydac]

You didn't explain about btrfs subvolumes, which is quite confusing to me atm, also do you need to have created the volymes during arch install?

[@nickdick2]

This is more related to the btrfs configuration, than to operating e recovering the snapshots themselves... You can take and recover snapshots even with other filesystems (ext4, etc). The making of the snapshot may take a bit longer than with btrfs...

[@jesse7631]

Interestingly, OpenSUSE implements this configuration perfectly when you select a BTRFS installation.

[@tolgayenici]

Imagine, I use Debian stable with btrfs format and timeshift. I can go back 20 different snaps during boot. After so many failures with many distros, I have settled with the Debian. I love all the distros of GNU/Linux but the Debian is the one for me.

[@richardbennett4365]

Just rewind to the checkpoint or snapshot that was created before doing the risky work. Gosh. Run Tieshift on btrfs and make hourly snapshots. Hell be fine, because he did these things. Other people who don't know will be 😭😭😭 crying.

If you had time shift on that system, you could have used a live USB stick for something like Linux Mint which includes timeshift. Then use time shift to access the location where your snapshots were stored and have hit restore your system.

This is a big reason why I'm not using Linux on Desktop. I want the latest packages, so Arch seems like a perfect choice, but the fact that a simple upgrade can break the OS is a huge no. On my home server is a different story, I don't need the latest software since most of it is using Docker so I use Debian and never worry about any of this. Immutable distros are the closest thing to my current setup (macOS), where the system is separate from the software installed.
