The Tasks of a System Administrator

System administrators are responsible for overseeing the operation of networks along with making sure that information technology is operating efficiently. A system administrator will typically oversee the operation of a network, which can include making sure that users are able to access necessary information, as well as the backups, are scheduled. The time that it takes for these back-ups to occur can vary based on what data is being backed up and how important this data is.

On top of overseeing the operation of a network, system administrators also have to make sure that the hardware and software used remain up-to-date. This is typically done by creating a schedule for upgrades to occur or by making sure that any software or hardware issues are fixed as soon as possible. Some of the tasks a system administrator may perform every day include backing up systems, installing patches, and updating system documentation.

The Work Environment

System administrators typically work in an office with other IT professionals. This is due to the fact that all of the software and hardware used to run a network have to be maintained by trained professionals so as not to cause any problems within the system or company itself. In addition, many companies often face legal obligations when it comes to data. This is why many system administrators work with a team of other professionals in order to ensure that all legal requirements are met and that the company follows any industry-specific regulations.   


In order to become a system administrator, you typically have to be educated at the university level or have a degree from an IT trade school. Many employers are looking for system administrators with degrees in computer science. Throughout your education, it is important to take courses that will allow you to obtain the experience needed to become a system administrator (i.e., computer networking classes). Many entry-level system administrator jobs require at least one year of previous work experience; however, this can vary based on the level of education completed.

It is important to note that system administrators can specialize in certain fields such as security, storage, cloud computing, and network operations. Specializations may require additional training or certifications that go beyond basic system administrator job skills.

In Conclusion

So in conclusion, a system administrator typically takes care of the day-to-day operation of a network. They make sure that the company follows legal requirements and that all backups are scheduled. In addition, system administrators have to keep up-to-date with software and hardware updates as well as work with a team of other IT professionals.
