As a Home Assistant noob, there’s some things that I’m just destined not to learn until I experience them and one such thing is that I should disable things I don’t use on devices I use. I have a bunch of presence sensors in my house and they were essentially spamming my logs with the motion state, something I never need as I only ever need to know whether a room is occupied or not.
Anyway, I didn’t think anything of the log spam until I did a backup, in two weeks my backup went from 5mb to 0.5gb I was like WTF? I digress… a quick search said it was safe to delete and it would be recreated automatically, so I did and now it’s back to 5mb and obviously I disabled all of the extraneous logging elements disabled. Since disabling wasn’t enough.
Just sharing what I learned.

Just out of curiosity: is it that bad if the database is larger? I love to have some history especially for my temperature sensors.
I have two temperature sensors and keep their data, but I was getting a tonne of spam from my presence sensors which meant that my database was 2GB and growing. That level of IO would quickly kill my SD.
For those devices that are very chatty you can specifically exclude them from being stored in the database. I then created template sensors that let me filter the results so I’m not spamming the database, only storing data I want. I do find the mm-wave sensors to be particularly bad, but I’ve also found Tuya-based air quality sensors to spam the logs too.
Ooh, how do you exclude from the db?
Recorder integration: https://www.home-assistant.io/integrations/recorder/
The simplest way in configuration.yaml is something like:
recorder: exclude: entities: - sensor.chatty1 - sensor.chatty2Thank you
