Hello Everyone,
I have a question regarding the btrfs subvolumes in Garuda. Particularly regarding the 2 "_backup_..."
subvolumes you can see in the following screenshot:
As you can see they use a lot of space, that's why I wanted to know where they come from and if it would be safe to delete them as I am really short on free storage.
Thanks a lot for your help :))
