Storage , System 25.3 G

Configuration
1

Hi,
I’m using Home Assistant OS 16.3 with HA Core 2026.1.1, running on Proxmox.

In Storage, I see that System is very large (about 25.3 GB). Is there any way to find out which files or folders are using all this space?

I’m using MariaDB as an add-on. My config.yaml recorder configuration is:

recorder:
  db_url: mysql://xxxxxxx:xxxxxxxx@core-mariadb/homeassistant?charset=utf8
  purge_keep_days: 7
  auto_purge: true

If I try to create a full backup and upload it to Google Drive, there isn’t enough space.
Of course, I’ve searched for answers on the internet and tried everything I found, but I still can’t figure out where this 25 GB of data is coming from.

Any help would be appreciated. Thank you!

Isn’t Google default limit 15Gb?

Yes, but this is not a question. I’m trying here to find out which files and where they are stored—what is making the system use 25 GB of space—so I can check why and what exactly is taking those 25 GB.
