System administrator responsibilities: 9 critical tasks
System administrators are critical to the reliable and successful operation of an organization and its network operations center and data center. A sysadmin must have expertise with the system's underlying platform (i.e., Windows, Linux) as well as be familiar with multiple areas including networking, backup, data restoration, IT security, database operations, middleware basics, load balancing, and more. Sysadmin tasks are not limited to server management, maintenance, and repair, but also any functions that support a smoothly running production environment with minimal (or no) complaints from customers and end users.
Although sysadmins have a seemingly endless list of responsibilities, some are more critical than others. If you work in a sysadmin role (or hope to one day), make sure you are ready to follow these best practices.
