our server is gathering log files. it is occupying our spaces vainly. how we can make it stop and not to gather again.we want to have offsite back up and don`t want to send unusefull data and pay for log files....
Log files are generated by several parts of your system, i.e. the mail server, webserver, login routines, security cron jobs etc. You have to consult the man pages of each of these daemons to find out how to stop logging.
Probably easier is to exclude /var/log from the backup routines.
I personally make daily off-line backups of my log files in order to be able to trace back hacking attempts in case my server gets compromised.
I think it is better for me to have managed service from data center.I have someone for doing these items... but it seems he is not qualified. I reported your advice to my server manager but he could not solved the problem.
