Backup folder taking hundreds of GB of space even though I eliminated all backups

I deleted all backups using the UI, but when I ssh into home assistant (on a Proxmox VM using Home Assistant OS) the /backup folder is huge (over 500GB and contains tar files dating back to 2022. How is this possible? Is there a problem with my installation? Or is something else? Thanks

They could just be relics of bygone backup systems. What do you use for your backups, just native HA or are you using something like Samba backup to send it to another server? If you use Samba backup it will auto prune for you.

I use Google Drive backups
