Craig Sanders je v nekem intervjuju zapisal:
What are your fundamental tasks as a sysadmin?
- To keep the systems running.
- To plan and implement upgrades and new services.
- To plan for disaster, minimising the risk and the potential damage, including backups and disaster recovery planning.
- To resolve any systems problems that crop up or, better yet, to see the warning signs and head them off before they become a problem.
- To keep my skills up-to-date.
- To be a knowledge resource for the company.
What qualities do you rate as essential for a good sysadmin?
In rough order of importance:
- Ability to learn and understand complex subjects quickly.
- Ability to hold a mental model of How Things Work.
- Caution and knowing how to make changes in a way that you can quickly and easily undo if you need to i.e. revision management skills.
- Communications skills – you need to not only know something, you need to be able to explain it to others in plain English so that reasonably intelligent non-experts can understand it.
Note that training and formal qualifications aren’t on that list. They’re useful, but only in addition to the above traits, not as a substitute for them.
Sysadmins are often accused of being control freaks. They are also accused of being vengeful people, who use their technical knowledge to harass users and keep upper management in check.
