Preventive server maintenance: cheaper than emergency repair
Do you know this situation: the server goes down on Monday morning, 15 people can't work, and every hour costs more? Painfully familiar to many managers and business owners.
But here's the truth: almost every server failure has warning signs — days or weeks before it happens. Disks reporting errors. Temperatures slightly above normal. Logs full of warnings. Systems running slowly.
These signs are only visible if someone is watching for them. That's exactly what preventive maintenance is.
What does 1 hour without a working server cost?
Let's do the maths realistically. A company with 15 employees, an average salary of €920/month:
- Labour cost per hour: ~15 × 920 / 160 = €86/hour
- For 4 hours of downtime: ~€345 in lost productivity alone
- Plus an emergency IT specialist out of hours: €100–250
- Plus potential data loss, delayed clients, stress
Total: €450–600 for a single outage. Without counting lost revenue and reputation.
The emergency repair is only the visible cost. The hidden ones — lost productivity, delayed deliveries, unhappy clients — are larger.
What does preventive maintenance include?
1. Disk health
HDDs and SSDs have SMART diagnostics that warn before a failure. With regular checks we can replace a disk before it crashes and you lose data. The disk is the most common cause of server failures.
2. Update management
Windows Server and Linux need regular security updates. An unpatched server is vulnerable to ransomware and breaches. We manage updates on a schedule — no surprises and no interruption to your work.
3. Temperatures and hardware load
An overheating server runs unstably and wears out faster. We track CPU, RAM and disk temperatures and react to anomalies.
4. System logs
Logs are the server's "diary". Errors, warnings, failed logins — it's all recorded. Regular review catches problems before they affect operations.
5. Backup testing
A backup that hasn't been tested isn't a backup. We regularly restore data from the backup and verify everything is fine.
The real cost comparison
- Without preventive maintenance: 2–3 outages a year × €500 = €1,000–1,500/year + stress + downtime
- With preventive maintenance: a monthly fee + zero or one small incident a year
The difference isn't only financial. Predictability has enormous value for a business.
Which companies need it most?
- Companies without an in-house IT specialist
- Companies with 1–3 critical servers (file, AD, email)
- Companies where IT going down means work going down
- Companies with important data (accounting, customer databases, documentation)
If your company falls into these categories, ask yourself: when was the server last diagnosed? If the answer is "I don't know" or "more than 6 months ago" — now is the time.
