Where is the database stored in Linux/Fedora?

[parasiteoflife]

I followed the steps in the wiki to setup the qbtuser and the service, I want to backup the data because I'm going to upgrade the system to 40 but I can't find the location where the database is stored, all I can find is the logs and some .conf files, where is the queue stored? Is not in a db? All I need to backup is the .config/qbitorrent directory?

This is all that directory contains:

categories.json
qBittorrent.conf
qBittorrent-data.conf
rss
watched_folders.json

Thanks

Also all .local/share/qBittorrent/ contains is:

BT_backup
GeoDB
logs
rss
