What does a remote Unix administrator do?

System administrators are responsible for maintaining computer systems to ensure the availability of data and applications. As a remote UNIX administrator, you maintain and monitor a UNIX-based server to guarantee optimum performance, perform upgrades and repair the system, and assist users with issues related to system access. Many administrators work from home and perform their duties via remote access protocols, utilizing skills in hardware and software maintenance, networking, and even information security to provide technical support, vet, install, and maintain software applications, perform routine data backups, and tune one or more servers to improve their performance.
