This guide outlines key dos and don'ts to help senior system administrators maintain robust systems, maximize uptime, and enhance efficiency.

Understanding the Role of System Maintenance

System maintenance encompasses all the tasks and processes needed to keep computer systems operating smoothly. This includes routine inspections, updates, security checks, and repairs. The goal is to prevent glitches before they disrupt business processes. As a senior system administrator, you are at the forefront ensuring that these activities align with organizational goals.

The Dos of System Maintenance
