Some important thoughts for system administrators

Full original in:

General System Administration Overview

  • Never do something you can't undo.
  • Always check the backups, never assume they are working. Make sure you can restore from them, too.
  • Write down what you did, even if you know you will never forget it, you will.
  • If you do it more than once, write a script.
  • Get to know your users before there is a problem, then when there is, they will know who you are and maybe have a little understanding.
  • Remember you are performing a service for your users, you don't own the system, you just get to play with it.
  • Check your backups.
  • Never stop learning, there is always something you should know to make your job easier and your system more stable and secure.
  • Check your backups, again.
