I once heard a speaker who worked as a Linux system administrator on Wall Street state:
"You should be able to pick any computer at random, throw it out a 7th story window, and have a replacement in operation within 2 hours".
The key is disaster preparedness and disaster recovery. Expect that your computer(s) will break, and prepare for it with backups. Verify your backups by doing recoveries and comparing the source against the recovery. [1] is dated, but will get you thinking in the right direction. A related technique is disk imaging. Another is archiving. Learn them all.
Learn how to write shell scripts (or Perl, Python, etc.), so that you can automate repetitive tasks and get consistent results.
Do not be afraid to spend money on a spare computer, spare parts, and bigger HDD's.
Keep records of anything and everything that matters. Use a version control system.
