Airlines, trucking companies, and other large organizations devote much more time, money, and effort to cleaning and preventative maintenance than they do to repairs. That’s because cleaning and regular system maintenance repay their costs many times over by reducing the frequency and cost of repairs.
It’s almost always cheaper to prevent something from breaking than it is to fix it after it’s broken. The same is true for your systems like UPS and PCs. The best way to deal with problems is to stop them from happening in the first place. That’s where preventative maintenance comes in.
A good preventative maintenance program incorporates a comprehensive backup plan, measures to secure the system against malicious exploits, periodic hardware and software maintenance, and steps to maintain general system tidiness.
The goals of preventative maintenance are to reduce the likelihood of hardware failures, extend the useful life of the system, minimize system crashes caused by outdated drivers and other software problems, secure the system against viruses and other malware, and prevent data loss.
