After the 2021.12.0 update something has changed. I don’t know what, but anyway, I’m happy with it 
The disk space usage stabilized.
The first growing part is with standard recorder from fresh install. Data grows.
By point 1. I did install MariaDB and excluded a lot of things, but it did not helped anyhow. Disk usage did grow again.
By point 2. I installed 2021.12.0. And see, the line now looks good.
So, I don’t know, who you are, I don’t know, what did you change, but I do know, that I want to applause for you very loudly. You are my hero
