One thing that comes very handy is usage of cron to make scheduled job to delete old files so that you can free up some space on your hard drive
# Delete Apache logs older than 60 days find /var/log/apache2/ -mtime +60 -exec rm {} \;
With this simple script you will search through Apache logs in folder /var/log/apache2, select the ones with access time older than +60 (60 days) and execute delete with rm command.
