@d19dotca totally agree on this point of view.
I tryed to run:mysql -uroot -ppassword PURGE BINARY LOGS BEFORE '2021-02-21 23:00:00';
and I saved around 2,5 GB...
I think Cloudron have two missing two things:Control of logs amounts and cleaning function; Control of logs to understand potentially threat and give ability to eg. block IP or block login attempts.
