Magento doesn't rotate logs like you seem to be implying. However, you've likely seen logs get rotated on some servers in locations like /var/log/ where those are rotated by the OS itself. On many Linux servers you'll find a folder called /etc/logrotate.d/ that contains definitions of what files/logs you'd like to rotate. Here's an example one I use to rotate logs for Magento.

File: /etc/logrotate.d/magento

/path/to/magento/var/log/*.log {
    su www-data www-data
    create 640 www-data www-data
    daily
    compress
    missingok
    notifempty
    rotate 50
}

This runs logrotate each night, compressing and renaming log files to only keep single day increments of the logs up to 50 days. The username www-data should be substituted for whichever user your webserver is running as.
