understand archives folder

[NicolasT29]

Hi
I regulary emtpy the archives foldes, because it take all the empty space (70Go)

I search to understant why it take so much place and where i can trigger option to empty after a certain time or modify the logs doneIf

For me 70Go after less than 1à days is not normal ...;

I send pictures of the diffrents type of file, if someone can explain which they are

master.tar.gz
mysql.date xxxx.sql.bz2 (may be automatic backup of the database ?)
loc-nagiosbp.datexxx.sql.bz2 (may be automatic backup of old logs ?)
eonweb.20200715.sql.bz2
ged.20200715.sql.bz2

thanks
