I've been trying to figure out how to use snapper, it's scary.
I read I need to make a Btrfs subvolume, how, I couldn't get a clear info on that, other than it's a subvolume.
What is a subvolume?
Is it created inside the Btrfs Volume?
The information say I should use a snapper command to do it?
I bet I read it wrong, but after 20min's reading the info over and over again, I'm getting more and more confused.
Am I just a bit slow (yes, I know I am, don't confirm it :stuck_out_tongue: )
I really would like to get a snapshot up, possible a schedule, like timeshift does it.

Where you read?

Use snapper helper. :slight_smile:

Yeah, that's one of them.
also

and
https://www.thegeekstuff.com/2014/03/snapper-command/

I'm fairly confused

Also searched for Snapper Helper, same sites, redhat, Arch Wiki comes up, but no snapper helper

I do not use snapper and can't help with this crash log.

If you include terminal outputs in your post please
use the proper output format in your post.
Using "~" 3 times above and "~" 3 times below the text block
will provide a readable, raw look.

Please edit your post.

Is there an alternative that might suit me better?

Sorry, but there were no terminal output, only a window with a crash report

Why, Garuda makes this for you before new update.

So if you want to learn Btrfs you must study it.
But we are here to help with Garuda Linux "problems", not to teach every programm that exist.

How to use snapper?

Do you open the garuda-assistent?
There must be all, you require/need.

Sorry about my English :smiley:

No worries, I understand what you write. All I wanted was a snapshot of my system :relaxed:
Another reason Garuda is awsome

It's all there, in Garuda Assistant, I'm so releaved, thanks SGS :relaxed:

Note that @home (/home) isn't snapped. If you'd like that to also be done, you'll need to set up a second snapper profile for it.

BTW, it is right, to be safe, that is not a backup solution.
Use other ssd/hdd/cloud for backups, please :slight_smile:

I always got 3 other backups, second partition, local server and cloud. :slight_smile: that's for home.
I don't see snapshot as critical as my documents, pictures and settings.
