Proper server administration is a critical piece to any successful business operation. Servers require observant technicians that can take appropriate actions based on information received from the client/server environment.
Backups not only need to be setup and properly maintained but also need to be restored in a test environment from time to time to verify their validity.
Techs need to monitor the availability of security updates and patches for production servers and update accordingly. Continuously monitoring the status of any raid array or redundant hard drive system is necessary to make sure the server is not at risk of hard drive or other type of hardware failure which could lead to data loss.
