Deleting @_backup subvolumes

General system Applications
#1

In btrfs-assistant i don’t usually keep backups of a restore. Is there supposed to be one there that is permanent? I tried deleting it and it won’t let me.

I have these 3 entries and i don’t think these should be there as i did a restore to an earlier point before messing with distrobox and docker and podman.

ID 957 gen 87297 top level 788 path @_backup_20220607194105797/var/lib/docker/btrfs/subvolumes/2dc6592f7b5a60811881011685711bd0dfc29b090ac7ea251dc8b318fb63c03a
ID 958 gen 87298 top level 788 path @_backup_20220607194105797/var/lib/docker/btrfs/subvolumes/26c639ccb76cf1f504fb0af4b91738f0478e1be985ab8b9102c287a36444598a-init

So i was trying to delete the @backup shown in the image and i wasn’t sure if this is actually the subvolume that it saves the backups to? Also how do i get rid of the 3 entries as i’m not sure where they are but looks like this is the backup that had them?

You can’t delete the parent until you delete the children.

Check the box below that reads “Include container subvolumes”

#3

I never had this problem before? Hmm… Which boxes are you referring to?

Edit: Okay i see at the bottom right but i have never done this before and i have deleted them lots of times?

sigh I need to see the screenshot with “Include container subvolumes” checked.

#9

The thing is the files and folder i don’t think exist as i restored to an earlier point?

Edit: Image is in the above post i edited.

You still haven’t deleted or moved those children subvolumes. They are inside your backup somehow. If you need them, mount the partition root and move them into the @ subvolume. If you don’t need them, just delete them.

#11

That’s what i want to do is delete them but i don’t know how to do it?

#12

Highlight them and click the delete button.

#13

I’m not sure where you mean?

Edit: Okay i did that but will i be able to delete the backup now?

Edi2: Okay that worked.

Thanks @dalto

If you delete those, you should be able to delete the backup now.
