The server logs store useful information about your visitors and accesses, our server mainly stores two types of logs:
The FTP logs. Logs that store login information to your ftp account (This must not be deleted in compliance with the LSSI).
This information is accessible through your plesk control panel, you can download and delete them once they have been processed.
Our panel also allows you to activate rotation features ie delete the older ones and classify them by size and date, due to the large amount of information that can be contained if your website is very visited.
