They are in root so do i put / in front of it or needs a space? It isn’t working.
They are not in the root of the filesystem, they in the root of the device. If you click near the area in dolphin at the top where it says root it should show you where it is mounted. Probably /run/timeshift/backup
Okay I see. I didn’t realize that. So would it be like
sudo btrfs subvolume delete /run/timeshift/backup/@-0gyqxf
Yes, something like that. Just be careful not to delete the other ones.
Okay… that worked but I’m still not understanding why it created them?
I don’t know why they were created. I don’t use timeshift personally. I prefer to have more control over my snapshots.
Well i don’t know much about this stuff so I’m just trying. How do you use it without timeshift then?
Edit: So i guess then when it makes a snapshot it is actually a snapshot of a subvolume?
What does this mean?
Edit: I didn’t set this? It was automatic.
The interesting thing about btrfs is that snapshots are also subvolumes themselves. That is why when you list subvolumes you see all your snapshots.
In /etc/fstab
, all those lines end with 0 2
. The 2
part of that tells it to fsck the filesystem in the second pass. However, btrfs filesystems don’t need to be fsck’d so they should be 0 0
. It won’t hurt anything because fsck.btrfs
basically does nothing. It is calamares that sets those wrong.
Yes i used the secret sauce ISO. So efi is set 0, 2 and / is 0, 1 the rest are 0, 2
Should they alll be 0, 0?
All the btrfs lines should be 0 0
, yes.
If it is a throw-away install I wouldn’t worry about it but if it is something you are planning to keep around might as well change it.
I’ll change it just because it helps to remember stuff. Thanks a lot i couldn’t have done it without your help! I learned a little although this was a lot really. Every little bit is a step forward. I would have just started over and given up.
this is how i’ve set mine when followed @2000 howto

Yes, i also have a set up from the wiki on another system. But this one i tried to setup myself without knowing how it’s supposed to be exactly and somehow my time shift created snapshots of / twice? So i was confused as i don’t really understand the whole set up but I’m starting to.
Edit: I think it probably happened because as @dalto said it doesn’t open dolphin on kde because time shift is running in root. So i probably was clicking on the buttons thinking it wasn’t working.
I know exactly what you mean, as i don’t understand anything ^^
Especially regarding timeshift… i’ve been thru issues that i didn’t succeed to comprehend…
and this is exactly what I need to do…
Apparently, as per the wiki, you wouldn’t need to specify the tmpfs entry for /tmp in your fstab
