In many companies, the IT department operates on an agenda driven by incidents and emergencies. But if you want your infrastructure to be stable, secure, and ready for growth, there’s a non-negotiable practice: periodic reviews.
A well-crafted quarterly checklist prevents costly surprises, optimizes resources, and gives you the peace of mind that everything is under control. The problem is that many organizations don’t have one… or they only do it “when there’s time” (which means, almost never).
At Sosmatic, we know that preventive maintenance is far cheaper than emergency recovery. That’s why we’ve prepared a guide to the key checks your IT infrastructure should undergo at least every three months.
1. Backup and Restore Testing
Having backups is crucial, but it’s just as important to verify that they actually work. Perform test restorations to ensure you can recover your data without issues when you need it most.
2. Access and Permission Audit
Review which users have access to which resources. Staff changes, promotions, or transfers often leave unnecessary access rights open. Reducing privileges to the minimum required (the principle of least privilege) minimizes insider risks and enhances security.
3. Disaster Recovery (DR) and Contingency Testing
Simulate a critical failure (server crash, ransomware attack, network outage) and measure how your infrastructure and team respond. The more realistic the test, the better prepared you’ll be for a real incident.
4. Hardware and Software Obsolescence Check
Unsupported equipment and applications are an open door to performance issues and vulnerabilities. Keep an updated inventory and plan for renewals and upgrades before they become emergencies.
5. Performance and Bottleneck Evaluation
Analyze CPU, memory, storage, and network usage to detect overloads or underutilized resources. This not only prevents downtime but also helps optimize costs and plan for future expansions.
✅ Final Tip: Document Every Review.
This will provide you with a clear history, allow you to anticipate problems, and demonstrate that your infrastructure is well-managed.
